I like the way you talk to the camera you (actually talk) it feels like we're having a real conversation. You're sharing your wisdom with us. Great teacher

[@johnbotirius9897]

Nice! Got to give it away to keep it. Giving Builds the soul

This!!!

[@tomtimor9789]

Agree with you. Good stuff.

[@matthewlococo3554]

well said

[@FractalPterodactyl]

Sir, where did you come from, you majestic KZbin unicorn? I've been digging through DIY youtube for months, just, like, piles of trendy videos about how to build a mid century inspired marble effect vinyl kitchen open shelving with hairpin legs, and here you are, very accurately describing to me the best way to keep my bathroom from turning into a rotten pile of mush. You have personally and directly saved me from the worst of my home renovation impulses. Thank you, so very very much.

[@HomeRenoVisionDIY]

Happy to help. Cheers|! BTW I have been here for 3 years.

[@randiehorton4535]

OMG, I'm a DYI weekend warrior. Have just ripped my bathroom apart to build in a walk in shower, new floors, sink, toilet, everything. I've been watching your videos for 3 days, cant get enough, and can't wait to really get started.

[@dawbxyooj1608]

Jeff the way you're doing and talking at the same time and thing. You are very professional. You must be a teacher because the way you handle your job seem so easy

[@wrightwster]

I like the way you show us the way to do the work in simple words and demonstration. You also explain why and how to do it.

[@HomeRenoVisionDIY]

Cheers William!

[@JSLEnterprises]

Redguard Pro Tip: You're note supposed to lay on RedGuard thick. its supposed to be laid on thin initially. You need to prime it. Thick right off the bat will crack as it cures from red to pink. especially at any seam or changes of plane. Also, changes of plane should be reinforced with either a mesh or fiberglass felt for full shower (wall to floor). Cracks = Water penetration = failure of the waterproofing. Jeff is doing wall to wall seams only.

[@jimpost1086]

My son and I are doing our second DIY dry bed shower using durock board on the wall . We watched all the videos and the best info on this video is using Red Guard. Tape you joint real good and RED GUARD till it bleeds . Jeff does a great job explaining all the system you can use.

[@HomeRenoVisionDIY]

Cheers jim, thanks!

[@daveeznyc]

Just bought a home in the states and I’m a retired carpenter.... I love how relaxed you are in explaining everything. Your videos are great 👍

[@robertokelley3236]

it's nice to see and hear someone go thru thoroughly..never heard of this system.but will try

[@danpenabad6350]

Big Diy guy here in the middle of my first master shower remodel. Your compilation video is amazing! First one I've seen that really explained the different ways and how they work. Definitely a member now and thank you so much for your hard work! Off to see how you do your shower base. Mainly scary part for me.

[@10aciousK]

You are a Godsend. I had to tear out a shower surround and the wallboard beneath it due to mold in a 110-year-old house. I do not have the resources to hire someone. I even took some bids from local workers and I knew their plan was to rip me off because they just weren't charging me enough. I know what the materials cost. I did my own research and decided to do it myself with the help of my son and use RedGard. At the end of this video, I lit up when I saw you using it. And you recommended using it in just the manner I was planning on using it. Thank you for your great videos and advice. We hang the drywall tomorrow.

[@najmehgriffin6478]

whenever I watch your show you give us much more information than other shows, and tell us more practical and lower costs, I like it, and learn more, thank you.

[@HomeRenoVisionDIY]

Glad to help! Cheers!

[@dfzurichch]

Fine job on all your videos. You explain it clear, and if I missed something I just play it back. Make it easy.....

[@656SM]

I have actually avoided costly mistakes because of your videos. Thank you. I am a lot more proficient in a lot of home construction areas. Keep up the awesome vids.

[@kennyhernandez5622]

thank you sir for showing people all the possible ways and the types of waterproofing one can execute using various products the right way without mickey mousing it through.The work speaks for itself the way you do it guy. Thanks again.

[@BrentWalterSmith]

You're the Bob Ross of renovations.

[@stolentoilet]

This video was super helpful! We are planning on remodeling our bathroom, full concrete walls and floors with a walk in shower, no lip or door. I think our plan would be to use cement board, a liquid membrane and then the concrete skim coat or 2. I am trying to do as much research as possible, but there are not a lot of resources for non-traditional bathrooms. Would love some advice!

[@HomeRenoVisionDIY]

if you have a slop that heads to the drain then a roll on membrane should suffice.

[@mandiebonilla-ortiz4059]

Can I do the version with Schulter Kerri-boards boards right to the floor. I have a claw tub and want to put tile on floor and wall. Also, I am feeling more and more confident the more of your videos I watch. Thank you sooo much! My father passed-away a year ago and we just bought our first house. The moments of struggle I will undoubtedly have while embarking on our DIY bathroom remodel make me feel comfort that I now have someone to “call” virtually (which would have been my father) for my questions. Thank you.

[@madipaysam4075]

I love your videos! You are like the Bob Ross of home renovations! You make every project seem simple and fun!

[@deloneyelda1159]

Hello, First off I want to compliment you for having by far the best DIY channel on the web. You Deserve a TV Show. Which type of water proofing do you suggest for a steam shower?

[@andrewrussell9034]

I have watched many of your videos and I really don't think there is someone out there who takes the time to not only talk about a specific aspect of building/ renovation but to talk and teach your viewers multiple ways in which to go about it ! Im a carpenter from Scotland and I could watch your videos all day ! I really don't think there would be a difference from learning in person or to watch you on the screen, you are very thorough and I never have to go back and "watch that bit again" its very easy viewing and Im sure everyone would agree we can tell the methods you use have been tried and tested which gives us confidence In applying them. Thanks again and keep up the good work ! I look forward to your next video. P.S you can tell your son is the brains behind the operation haha

[@CyndiLH]

You are bang on about using modified mortar...I just learned the hard way....luckily the cement board wasn't properly primed so it was easy to peel off the red guard that was applied...LOL...or maybe not...

[@siqwithit]

I really liked the third system in this video, do you have a complete start to finish video on that install? The custom shower pan seems like what I would have to do. Great Video and thanks again.

[@dkeever]

How about using cement board and RedGuard? I have used all the systems that you've showed for waterproofing showers. I have found that I usually have to demo drywall anyway behind old shower walls, so i just replace with 1/2 Durock, tape the seams and install RedGuard. Seems to be the fastest most cost effective way for my area here in Charlotte, NC. I really love your channel, you are always very thorough, and you explain your process very well. Thanks. Casey K

[@djinconroe]

I very much appreciate how much detail you go into in these videos. I'm about to start a bathroom remodel and I chose the KERI-BOARD over their liner because it seemed to be a better fit for my abilities and I'd rather spend a little more on something that's going to get me tiling in fewer steps.

[@bobbyfischer7609]

We are doing our whole bathroom and we are doing the Redgard option in the shower. This made us both feel 100% confident. Thank you.

[@HomeRenoVisionDIY]

Cheers Bobby, sounds like you have a good plan there!

[@shanehb]

You have some helpful videos on certain things. Showing products that work with the Kerdi system when the Schluter products you need aren't available. If you are using these products while being a contractor is a no-no. Using these products can void the Schluter warranty if you end up having a problem. I take pictures of all processes while installing this system to protect myself. I am Schluter certified. I do a lot of high end custom showers. I occasionally take my Schluter book out or watch my DVD as a refresher course. Honestly I think you should do the same. I know you are trying to help people and that's great but I do see some things you could brush up on. I'm not trying to offend you I'm just trying to help a fellow tile brother out. Keep up the good work. I enjoy the videos.

[@embecmom5863]

as he said, if the shops dont sell it you are already buying a product thats warranty is basically a waste of time.

[@fabrenocon02]

Excellent tip for the installation of the Schluter Niche. I have done it before and I got awesome feedback from my customer.

[@HomeRenoVisionDIY]

Thank you! Cheers!

[@suep.3334]

Hi Jeff. Great videos! I am in the U.S. Can't seem to find the LePage 2 in 1 seal and Bond. Is there another brand you can recommend? Thanks.

[@markchristensen9524]

Great videos. When installing the Kerdiboard, I noticed that you went to the top of the tub lip and then ceiled the gap with the caulk. But the tub lip sticks out beyond the Kerdiboard so how will the tile (which would overlap the Kerdiboard and tub lip) be flush?

[@fattony123082]

Does anyone else feel like they can concur any project after watching this guy??? 🤔👏🏻👏🏻👏🏻

[@jesswyatt2511]

You sir are one if not "The" best DIY construction video host I have seen yet on here. You are very clear, knowledgeable, and very thorough with your videos as well as adding little tips and things to watch out for to the point that you provide a lot of information in a short time and makes for a much more enjoyable video to watch. Thank you very much for your videos and for sharing informative views and ideas.

[@HomeRenoVisionDIY]

Cheers Jess!

[@jpcool3000]

Great Vid! Thanks for all the info! I would love to see a video of do's and dont's for durock/cement board backing on shower installations. A more detailed video going into things to know when installing the board at the shower pan. What to know and how to install the board on over shower pan pvc liner. I've seen many different techniques with basic explanation, but not found one that is detailed from absolute start to finish. Could you give some advice in this regards please?

[@MrSaul2fl]

A homeowner here. I thank you for your informative videos. Very much appreciated. God be with you :)

[@HomeRenoVisionDIY]

Thank you very kindly!

[@woodysranch2690]

Jeff, at 37 min into this video you installed the shower valve seal backwards. I did the same thing by mistake. The theory is the slope on the rubber seal is supposed to channel the water to the shower side, not to the inside of the wall. Very insidious detail, and unlikely to be an issue.

[@Rebollozo247]

Great video. Im getting ready to redo my home shower because the previous owner didn't water proof the walls and the tile is starting to fall. Those were some great ideas. Just gained another subscriber.

[@HomeRenoVisionDIY]

Hi Jesse, in most cases the shower comes without waterproofing from the builder as well. Cheers!

[@kmonk7853]

Awesome videos Jeff! I've been a contractor for years and you have a really nice way of explaining things, very practical and flexible. There's always a different way to do something that is right and doesn't break the bank.

[@HomeRenoVisionDIY]

Cheers, we like to cover best practices and best options so folks have choices based on budget restraint.

[@danielmaclellan7003]

I like the realism and honesty!

[@marcellomastroianni6725]

Well done....very informative , well rounded, and nice to see different methods/options. One comment, while I think the Schluter system and products are awesome and as you pointed out a costly option. I'm not sure mentioning the warranty of that system is warranted given that there is no warranty from the instant you introduce your Lepage seal and bond product in place of the shluter caulking that is not readily available. My only concern is that the better part of your audience is DIYers that will follow you procedure to the letter and in the event somewhere along the way they slip up and it results in a failure of some sort, they might think, no problem , i paid the top dollar for the high end product and Jeff said it had a 10 yr warranty, which will be voided. As you clearly stated, it is warrantied providing it is installed per spec. IMO, even if you can't get the shluter caulking/sealant at the major big box stores, if you're going to spend that kind of money, it would be advisable to order it online ....find it and buy it from whereever you must......otherwise, you're probably far better off with the more cost effective red guard option.....just my 2 cents

[@jasonbusse5025]

Best Bath remodel channel on the internet. Really helped me plan my remodel. Now, I feel really confident. Thanks for sharing the knowledge.

[@dans8086]

Thanks for being so thorough with the how's and why's while keeping it simple. Awesome video.

[@thomasnorthcastle4130]

I have used Schluter for 19 years and it is a superior product!!!

[@HomeRenoVisionDIY]

Cheers and have a great Christmas!

[@scotty4899]

Really like these compilation videos! Would be great if you had more details in the video description outlining the materials used and when in the video the material is shown. That way it makes it easier to skip to the specific products/materials we're interested in

[@JohnDenverized]

Love your videos Jeff. We need your help though.... I've seen video after video where you are cutting out the old drywall and then installing cement board, or kerdi, or Mold Resistant Drywall and then you leave a gap where the old drywall meets the new product. See 49:14 in the above video. How do you finish that transition between the old and the new? And who do you do it so it doesn't look like a transition?

[@bobnewman1810]

Mud job tiled surrounds commonly last 50 years or more without mold or rot issues, and are often torn out only because the tile is out of style. They last because there is no paper in the surround, and any moisture that does weep in can dry out without issue. Durrock is the modern equivalent to that time proven system; same approach, but less labor intensive. It's also inexpensive. Other than Durock being heavy, I see few advantages for the DIYer in paying the high material costs for Schluter's system, especially the variant that uses paper faced drywall in the surround. No matter how loudly they claim it's waterproof, no installation is perfect. The important thing is how the system handles small amounts of moisture that eventually will penetrate, and for that, a cement based substrate is better. If you actually read their warranty, you'll see it covers only the failed portion of the assembly, and there are other limitations...don't expect your shower to be rebuilt for free. For the pro, Schluter's system may reduce labor costs enough to offset it's high material cost; I don't know about that. Whatever the case, it's silly to pick any system that has paper in the shower when other equal or lower cost alternatives are readily available. My 2 cents.

[@HomeRenoVisionDIY]

Hi Bob, I agree in principle that no install is perfect. That is why I love Schluter. It is engineered so beyond perfect that anyone trying to do a good job cannot possibly screw it up unless they do it on purpose. In the world of DIY I trust homeowners to do a great job with good information. I don't trust contractors to have as much integrity!

[@anon31415]

I am a total amateur DIYer. I have done two showers and will do two more in my new house. All the DIYers that I know are doing it to save money. They don't have money to burn. They also want to go to home depot or lowes and get the material. Cement backer board, backer board screws and finished off with red guard are all in stock and the big construction stores.

[@TileNation]

Bob, I must take issue with one of your claims. "The important thing is how the system handles small amounts of moisture that eventually will penetrate, and for that, a cement based substrate is better." Just to understand your claim Are you referring to a Water in/ water out pan with a durock wall substructure as being superior to a topically applied sheet membrane utilizing a bonded flange drain assembly? NOTE: you didn't mention a vapor barrier behind the CBU? (TCNA B-415, ANSI A108 02 3-8) which is necessary if you are not using a topical waterproofing membrane (ANSI A118-10). While both systems are approved there are many disadvantages to the traditional method in a modern home. The two most relevant are The traditional method does not handle changes in plane (Niches, Benches, curbless, and many curbs. This is a primary cause of residential shower installation Failures in the US. The surface membranes solve this inadequacy of the traditional mudbed/CBU. The second issue. Modern homes are very air tight to meet energy effency standards. When a shower leaks into a cavity where it used to evaporate today a small leak will wet rot and mold, this becomes a health hazard. Because CBU / vapor barrier behind (let alone CBU only, which you seem to suggest) installs are much more likely to leak when the above details are included than with a topical waterproofing system even if the competency of installation is marginal (Schluter in this case) It would be wise to to use a topical membrane.

[@seephor]

I disagree. The problem is not that water will eventually dry if it gets into the mud, it's that if the shower is use daily (if it's the only shower in the house that's pretty much a guarantee), there's not enough time for the moisture to dry out so it just collects and collects and mold eventually grows behind the mud and you get all sorts of issues. Waterproofing is really the best way to go. Prevent water penetration from the beginning.

[@jeffpowell8308]

Bob the problem with cement boards is that they do not have the same thickness or more importantly the density of the old mud set systems of days gone by. My experiences inform me that you are correct about the old mud set system. I've never Once found rot or mold behind those old assemblies. I have found lots of rot behind cement boards installations where it was the only thing installed on the wood substrate. Cement boards are not water proof. No exceptions. They are water resistant only. Meaning they are not affected by water but they do not stop the migration of water into the substrate. I installed that system for many years but I recognized the limitations of it so I developed work arounds. I always installed self adhesive and self sealing flashing on the face of studs so that water could not be absorbed into the studs. This was before I researched and then attended both of schluters 2 day seminars/ workshops. What they explain in great scientific detail is that their membrane is completely water and vapor Proof! When installed properly, water in any form cannot find a way through their system. That's why it's fine to use paper faced drywall. I was skeptical of the system the first time I encountered it but after having the science explained to me I use it with total confidence. Not because of the warranty (I quote the late great Chris Farley "I'll take a dump in a box and mark it guaranteed, I've got spare time, but what are you gonna have? A estranged piece of shit") I trust it because it makes scientific sense, that it will perform better over the long haul than my augmented cement boards assembles ever could. While I remain confident that those showers don't leak water (I've yet to get a call back in 15 years) but those could never be moisture vapor proof so they are susceptible to mold. Since the schluter is so much lighter, easier and tremendously better at its intended purpose it's foolish not to use it.

[@leeboriack8054]

Appreciate your sharing the positives and negatives of different techniques.

[@OriginalNameNick]

I don't know how anyone could give these videos a thumbs down. Such a treasure trove of info. I'm about to use the Redgard since that's what the tile installer recommended. I'm way more confident on how to do it now. But now i'm way less confident that it will last the lifetime of the tub! Thank you again! I am tackling things around the house I never thought I could!

[@jerrybobteasdale]

Good demo and instruction. Consider throwing a rubber backed little bathroom rug into the tub or shower while working in there. It protects from scratches and dings.

[@danielcraig7225]

ive been installing tile for 12 yrs and we always used du-rock and tape and thin-set, never had any problems!

[@Eastbaypisces]

so you don't need a waterproofing membrane?

[@robgreenough1164]

Still need red guard,durock is not waterproof

[@AshPagelsdorf42]

you are an amazing teachers and builder. i commend you on all the videos on here. i am planning on a remodel of my bathroom to convert it into a walk-in floor to ceiling tile. coming across you channel was a blessing, i have now been researching all the products you recommend. once i am ready i will also be taking many before and after photos and videos and i will share with you what i accomplished due to your tutorials. also another shout out for using perfect low background music !

Thanks Ash, best of success in your project. If you have any questions feel free to drop them in the comment section. I will get back to you. Cheers!

[@Teaganderry]

Thank you, Jeff, for making this look simple enough for me to try myself. Previous homeowners used drywall and luan! Now I have mold behind the shower. With this and your video on replacing plumbing with PEX, I'm ready to do it right! I appreciate your videos. I always lean so much.

[@tonybruce1863]

I bought a old house that home owner or someone had installed a tub/shower system from one of the big box stores. As time has went by the sheet rock above the wall. Which is about 5 ft has stated to fall apart. What can I do to repair this? By the way your channel is super good. Thanks for taking time to help out Johnny home owner.

[@HomeRenoVisionDIY]

Simply cut it out and replace. use a paint for bathrooms to avoid this problem in the future. and seal the edge to the shower with a silicone bead caulking. Cheers!

[@rodneysmith1750]

I love to to see the "old tried and true" methods and you are an excellent guide and teacher, thank you for your dedication to the crafts you are a pure joy to watch!

[@kalemburns4205]

Great video. Any videos that have a window in the shower area? Trying to figure out the best way to tackle this. Thank you.

[@espy0008]

You should always use a damp sponge over your drywall before applying thinset for the kerdi system. Same goes with any tile installation, you dont want your walls to get its first drink of water from your mortar. This is extremely important when installing tile over Hardie board. A dry wall or floor will draw too much moisture out of the mortar, reducing its bond strength. In the case of very dry underlayments like Hardie board so much moisture can be drawn out of the mortar that it can cause it to break bond with the tile itself.

[@dmithsmith5880]

Actually a concrete bonding agent should be rolled over any drywall or plaster to avoid any bonding issues.

[@chrisj197438]

dmith smith Water works fine if you keep it wet ahead of you

[@Cris5598]

Paranoid much?

[@dmithsmith5880]

@@chrisj197438 It does, but the bonding agent really works good at keeping it wetted. Nothing sucks worse then a dry bond on sheetrock.

[@rugman1970]

He skipped the the most important step. He failed to give the Sheetrock a drink.

Hey Jeff thanks for the video love how you showed the different ways of WATERPROOFING a shower. My wife and I just purchased a home that was built in 1956 that needs a lot of updating guess what I'm doing in spring lol The shower and I need it to last so again THANKS FOR THE VID

[@HomeRenoVisionDIY]

My pleasure, cheers!

[@cwhiseant]

I just replaced a shower with a jetted tub in our master bathroom, used James Hardie hydrodefence "waterproof" cementboard backing, then used Kerdieband on all the seams. I'm not a contractor, but I've done about 4 showers this way and it seems to work. I've been tempted to try the redguard method, but so far the idea of putting it directly over drywall has made me too nervous. Lol.

[@sentientarc]

GREAT CHANNEL! I am DIYer building whole house of just over 400 sq. - your vids REALLY help. Will be older soon, want it right and lasting for years. Q: The Kerdi Gasket you used in Vid 3 for piping and fixture thru holes: The gasket had two depths and you inserted the thicker depth into the wall. Is the gasket thickness for different tile thickness or does the thicker side ALWAYS go inside (why)? If 2 allowed, Unmodified Concrete for Kerdi was made clear but regular thinset with adhesive still used on top for tile mounting (Yes/No)? Very Grateful, Thank You!

[@HomeRenoVisionDIY]

non modified for eveything. Cheers!

[@bestmom4hb]

Thanks very much. I’m getting ready to do our daughter’s’ bathroom. And this video helped tremendously. I feel comfortable now not using cement board or messing w/a complicated membrane system.

[@njneer7511]

Love all your videos Jeff. Thanks. I am curious about the roll-on waterproof membrane. Now that you've created a new surface of membrane over the drywall, that's what the thinset for the tile is going to stick to. Does that have enough integrity so that the weight of the tile wont just pull the membrane off the drywall? Thanks

[@powersonic6255]

You are a awesome teacher , you have made me quite confident that I can do my own bathroom .... Thumb Up you and your channel .

[@bobmccutcheon7398]

Great hints one thing that drives be crazy after fourty years in the trade is setters who don't protect the tubs a peace of scrap carpeting makes a perfect cushion for both walking on and dropping tools if you have to replace a tub there's your day wrecked. Home Depot used to carry the notched trowel for kerdi may wanna check.

[@HomeRenoVisionDIY]

I prefer a thick moving blanket instead of an old carpet.

[@PrinceCbass]

I use painters tape along the top edge of the tub. I use 2" tape and tape over the lip into the vertical section of tub. It can stay there until you have installed the grout. Then you just peel it up and throw it out. Maybe $1 in blue tape and the tub edge is protected. I use cardboard for the base of the tub and an old drop cloth or my old grout cleanup towels to give me some padding in case I drop a tile or tool or anything. I chipped the porcelain on a tub once and I almost cried. Not again.

As soon as the tub is installed I box it in with plywood, leaving enough gap around the edges for backerboard and tile. I can walk on it, dance on it, drop tools on it, park my truck on it... After seeing another contractor have to replace a $1500 porcelain tub, I don't mess around when it comes to protecting them. Blue tape the gap to keep out dust and granules, cut the tape back as needed when tiling, grouting and caulking.

[@johnlee7085]

@@tedspens Similar to my thought except to just make it a flat platform. I couple padded 2by's at the edges keeps it in place. Would seem especially beneficial if doing multiple tubs. They're all the same size to you move a partial sheet of plywood that's a few inches thick from job to job with a little tape to seal the edge each time. $0.02

We're planning to use mold resistant drywall and paint on a membrane (AquaDefense, or RedGard) in our basement apartment's tub/shower. We are going to be installing a tub/shower surround that is only 58" high and is the "glue to wall" type. We're trying to figure out what to do from the 58" mark to the ceiling and the ceiling itself. Should we paint on this membrane all the way to the ceiling? If we do that, can we paint over it with regular kitchen/bathroom paint? Could we get away with only putting the membrane behind the surround and using regular kitchen bathroom paint, directly on mold resistant drywall, from the 58" mark up and on ceiling? What type of glue will be sure to adhere to the membrane? Or, will our plan be completely foiled because the glue may pull the membrane off? Thanks in advance! We love your videos!!

I've watched soo many of your videos and it has helped me tremendously! Thank you for sharing your skills in a easy, straight forward way. I will be using the kerdie board system this weekend. Thanks a bunch!

Jeff love your stuff buddy👍 I'm renovating a rental property that is a duplex.Im keeping the cast iron tubs as they are in decent condition. I have gutted the one bath and installed new faucet and drain and stop. I put new green board drywall around the tub. I already taped and mudded the entire thing. I was going to use a glue on shower surround. Do you recommend putting the red guard water proofing on before using this type of shower surround? Maybe I should red guard it and just tile it? Watching this video I guess I did not need to tape and coat the joints? I guess I won't on the second bathroom in this duplex. These shower surrounds do not go all the way to the ceiling either so should I red guard to the ceiling or just behind the surround? Can I paint regular white paint over the red guard at the top? One last thing will the wall surround adhesive stick good to the red guard? Do you recommend a different way to tackle this? Its a rental so I want it to last but not break the bank. Thank you for your time Bondo

Thank you Jeff. You are an outstanding teacher who inspires confidence and teaches the Why's. Love your videos.

Jeff, I've been watching all your shower video's. Thanks, I've ran my installed the valves, shower pan and ran the pex as you demonstrated. I intend to use the Schluter Kerdi board/system for my shower walls. What I've missed is what's needed for the ceiling? I will have a rain shower head from the center of the shower, plus the usual shower head. I know I can use the Kerdi board for the ceiling but at $100 for a 4x8 sheet, maybe I"m wasting my money where I don't need that level of waterproofing protection. Should I use mold resistant drywall, etc. Please advise. Thanks!

[@costaschionidis7098]

Thank you for the wonderful tips truly nice to see somebody who gives more than just one way of doing things but my question is what do you use to seal the grout what kind of sealer’s there is available.

[@cainKuri]

45:50 the most useful information for me... amazing... is what I was missing... thank you so much.

[@rickgogo96]

Thank you very much. I am about to do my bathroom shower and tub. All these information will help.

[@erickarobinson3981]

Hey Jeff can you do a video on taking a tub out and doing a walk in shower. Shower pan/shower curb etc

[@thomasnorthcastle4130]

Ericka Robinson go to Schluter site

[@joycecalderon5888]

I second this !

[@ek9772]

Great summary of different bathroom waterproofing techniques. I did get a bit confused in the installation differences between # 1 & # 3. They both use the Schluter membrane. So what is the difference? Is the difference in installing it over a bathtub in the first and a walk-in shower in the second? With regards to # 4, could you provide information on a couple of other liquid membranes you might recommend for bathroom waterproofing?

[@shanehb]

TEC makes a liquid membrane.

[@puppet022]

Well done, Jeff! I liked your comment about being able to create a shower niche at the right height after some of the tile has been placed. Maybe you can demonstrate that further in a later video. Cheers!

[@HomeRenoVisionDIY]

definitely. Cheers!

[@johndiaco7825]

Your video are great you exactly explain what best for each job your video on loved retile over old tile was awesome

[@ronebakuwel5353]

Thank you so much for making the time and effort to produce these fantastic videos. Although I am from Australia and we have different products available, your content is really informative. One "HUGE" thumbs up for your great work. Please keep it up. Cheers :)

[@stefanboedeker2694]

Is the roll on membrane good enough for a steam shower if it is done dry well? If not, what do you recommend also considering there will be a rain shower and 2 LED lights. Thanks much, very informative videos.

[@onpointa1]

Awesome demos for sealing systems! Have removed a tub and building a shower enclosure which is being built on existing concrete floor, single story residence in Arizona. Just grateful for the best advice to properly seal the entire system correctly. Thank for all the video instructions! Absolutely needed and hoping I don't screw it up!

[@HomeRenoVisionDIY]

Hi Jim, I hope all is going well. If you have any questions feel free to ask in the comment son any video. Cheers!

[@johnbotirius9897]

your statements are true about tile installation. mortar base adhesive for stone tile is the best way to go. Personally I have repaired 100 year old shower surrounds an they were made to last. Also Installed from scratch , the want it now install and custom. you speak Truth.

[@HomeRenoVisionDIY]

Cheers John!

[@nezayork1133]

Hello for obvious reasons I like the last water proofing method but what kind of material I need to attach the tile to that type of drywall? I will really appreciate if I got an answer thank you

[@CrosshairLunchbox]

Did I miss cement board? I see that more in your newer videos. How does cement board compare to mold resistant drywall? Based on what I have seen on your channel I think I would choose cement board.

[@iLikeC00kieDough]

How does it compare in terms of what?

[@chrisgraham2904]

I agree and cement board is still a common and economical product. Not sure why Jeff didn't address this. The only problem I'm aware of with cement boards, like Durock, is that they are heavy to work with and take a little more effort to cut.

[@markleblanc6974]

Your compilation video is great. And I really appreciate the concise to the point format. You don't waste any time getting your point across.

[@dmithsmith5880]

IMHO The best system is #30 felt paper directly stapled to the wall studs, lapping inside corners both directions and lapped properly from the pan up to the ceiling then a fat bead of silicone applied on top of the felt over the staples on each stud then 1/2" cement board screwed directly to the studs. Then mesh tape all the joints before tiling. ..that's how I have built them for a long time and never had 1 issue. Nothing bonds a tile down better then good old fashioned cement board. Easy to install, easy to build custom boxes, shelves, seats, the entire system is the cost of a roll of felt and a couple tubes of silicone $20 👍

[@picklerix6162]

I am wondering if you could also use a lightweight synthetic polymer underlayment instead of the the felt paper. The synthetic underlayment has replaced felt in roofing applications and most roofers recommend it now over felt. I suspect that the underlayment is much easier to install than felt but would probably be more expensive than felt.

[@dmithsmith5880]

@@picklerix6162 You could use anything waterproof really. You could use Tyvek, 6mil poly, etc.etc. but I would still keep it 3ft tall pieces lapped like 8 inches from the bottom up, it provides a small amount of air exchange into the wall cavity and would keep it from getting mouldy.

[@brianlawrence9493]

Your video are so informative I love watching all of them and I learn so much each and every time. This video has made up my mind on which water proofing method I'm going to use in my shower this year. I feel the mold resistant with the RedGard is just hands down the best for the price. Thank you! Keep the videos coming!Lawrence

[@HomeRenoVisionDIY]

Great choice Brian, You will be very happy with that product. Cheers!

[@johnk815]

I using Hardi backer and red guard with large format porcelain tiles on top. What type of thinset do you recommend? I wish I had a contractor in my area like you.

[@HerrBag1]

I would stick with non-modified.. You are essentially the same as Kerdi, AFA moisture sealing. Modified thinset doesn't cure properly when between 2 impervious surfaces.

[@colleentettleton5309]

Thank you for this information. I truly appreciate it.

[@basira.s9412]

Hi Jeff I have three kids they take shower everyday and sometimes they even spray water on bathroom ceiling Do I need to waterproof the ceiling? Look forward to hear from you Thanks

[@triciarobertson1455]

Hey Jeff, having trouble finding a solid answer to this question, I just got our shower hot mopped and I want to use Kerdi Board on the walls, but I'm wondering if I can use the concrete and Kerdi tape method to seal the Kerdi Board to the actual hot mop tar flooring or if there's a better way to seal it to the tar? Thanks so much!

[@orrphism]

Which of these are the best bang for your buck? How does Kerdi membrane method compare to the Redgard method? Will be doing this soon in my bathroom. Thanks for your videos!

[@HomeRenoVisionDIY]

depends on the level of paranoia you are dealing with. For a tub/shower the redgaurd will last longer than the design. If you are doing a custom shower with tile base I would recommend using the schluter system. That is a life time build.

[@rangerfan75]

I’m using redgard for my tub/shower walls. Want to know what type of mortor I can use over the redgard. Thank you

[@tjnor23]

What did u end up using? Im trying to find out what thinset is recommended for over redgard

[@colleentettleton5309]

Has anyone found this answer?

[@jasontian9450]

Hi Sir, you are so good at these things. Can I ask you a question? I have my contractor put on cement board without putting waterproof membrane for standup shower. Is there a way that I can just put another layer of red waterproof sheet from your first option on top of my cement board? at the bottom of the sheet, I will cover the waterproof membrane with red sheet to install tiles. please tell me what the right way is to put the membrane in my situation. getting really stressed here. :(

[@jeadie8131]

I was always told that the place most likely to fail was where the lower edge of the wall met the top lip of the shower. When the tile came down over the lip, water could wick up behind the tile and start molding or tile failure. This seems to be glossed over in this video. What am I missing? You mentioned that the cement in the corner in the segment on the Schluter tape is supposed to expend below the corner and is cemented in. BUT, nothing seems to be done for the rest of the length where the tub joins the wall. Is there a time in the video you could mention that explains this? Cement is much stronger in compression than in tension. So, don't try to stretch or bend the cement if you want to avoid cracking it. One of the ways to avoid weakining the seal between wall and tub was to put weight in the tub while it set up. When the water was drained, the cement would relax and be slightly compressed. When the tub was used, the load on the cement would not be any greater than what it was when the cement first set. Is this still good advice? Thanks for the videos. PS Thanks, too for pointing out the differences in product availability between the Canadian and US markets!

[@DancesWithPen]

He mentions this aspect in another bathroom renovation video. Guess you gotta watch them all and take notes

[@JEESSZZOO1]

I thought the Kerdi bd in 2nd video should come down to overlap lip of tub not quit touching on bottom, leave a small 1/4" or so gap?

hi Jeff, I am a lady and and I am in Canada. I 've been watching your videos for quite a while and I 've never seen you to work on concrete. My driveway is 2.5 years old and the expansion joint in cracking and getting bigger. Do you work on that type of field? I would love to watch a video about it. Thank you

[@spencerlinke7033]

If I would use durarock with the last way will it last longer and have better results?

[@lostinmyspace4910]

If you're talking about water resistant liners, could you consider a liner that is rubber, and thick which is used for making water features like fish ponds, and the like for landscaping. I think it's made by Goodyear Rubber. I can buy it and have used it against foundations to waterproof an area that otherwise would absorb groundwater, and also for water features. I can buy it in bulk off a 12 foot roll any size I need. Can there be a way to adhere it to a wall evenly and assure it will stick? It is rubbery, and supple, but will cement stick to it? If there's a question about length of time a product would be waterproof, I feel this might give a 50 year assurance or greater. This is just me thinking about durability, and longevity. I cannot live with the idea of redoing a bathroom after 10 years or so, and believe in overkill for the sake of the home, the house that shelters us in comfort for generations to come. I don't believe in cheap floors, MDF cabinets, cheap windows, and 20 year shingles. Pay good even if it hurts because down the road, you'll be kicking yourself in the butt for not doing the right thing out of the gate. Yet, if you need to camouflage a problem for the sake of selling the house to an unsuspecting new buyer, by all means screw them into thinking they're getting a new bathroom, and shame on you. This is just my opinion. Thumbs up for your review, and double thumbs up for a response. Thanks!

[@HomeRenoVisionDIY]

the pvc liner has a few defects in thew install technique that allow for major problems and smells down the road. This is a much superior system.
