I watched tons of your videos before I did my bathroom it came out great,3x6 curbless shower a soaking tub with a schluter heated floor in the entire bath plus the shower and bench after watching your videos I used the Flo-fx drain and all schluter waterproofing and all set and because I’m a beginner I hit all the exposed thin set with Hydroban THANKS for all your knowledge.

[@palmerstile9379]

Flofx membrane is the best on the market for sure, very thin and yet stronger than schluter.

Sorry for your loss, mate. It never gets easier does it.

[@HamiltonTileGA]

TileCoach, we're building a shower just like this right now. Two actually, but only one is curbless. We used white 8+9 changes it up a little bit. When you waterproof with 8+9, you gotta wait 3 days to waterproof for the pan to dry, they say. But that blue flo fx membrane and the branding they do on it, is slick. I mean, prep is fun. Try to get this stuff as tight and precision as possible then tiling is fun and turns out better.

[@tofuroshi]

Best to waterproof the entire bathroom floor for curbless showers in my opinion (looks like the crack isolation in this video also serves that function). This will protect the floor in case of water wicking vertically through the thinset/grout and offers a little insurance if the drain backs up since there is no barrier to keep the water in the shower.

[@EtreTocsin]

But the sheets are 78 inches wide. So do you tape / band the joints?

[@tofuroshi]

@@EtreTocsin you can transition to a roll on membrane or use Ditra with banding to waterproof the room

[@MakesCache]

I had a lady who left a wash cloth on the drain for what she claimed was a few mins but sent water all over the bathroom. It definitely can happen lol.

[@mankatovalleyseed8557]

Thank you for all the work and effort you put into your videos, tests, and tips. You are make me and the industry better! You have also inspired me to start doing my own testing and improve my efficiency. I have a question regular 😮installing waterproof membrane instalation and lapping. It seems to me it would make more sense to install the membrane on the shower floor first, then do the linear corner strips onto the floor, followed by the corner prices and finally, the shower walls. If the wall membranes were installed last, the water shed would be better. It always bothers me that the overlap invites water in if the linear strips and corners are installed last. Am I overly worried about this? Is the bond and seal of the membrane on membrane overlap so good, this is a non-issue? My other question on membrane is; when installing them on shower walls, can I use the NoFlo large sheet, start at one corner, and work the sheet into the corner without cutting it and continue on to the other walls without cutting the corners? Just thought it would prevent a lot of potential failure points and eliminate vertical corner strips. Am I missing something?

[@nastynateyj]

Great video! It's nice to see the products you sell on your site in use. If you were doing a curbed shower, what style/method/brand of curb would you use with the FlowFX membrane system? FlowFX doesn't offer curbs from what I can see. Would an RSS or Kerdi curb be compatible, or is it not recommended to mix and match brands like that? Thanks Isaac!

[@jt5747]

What does the lifetime warranty actually cover?

[@johnwhite2576]

[@gallardo360]

[@joedime1]

Another great video Isaac. I've watched a lot of your videos and notice you use a lot of different products. Is it because of different styles of showers, or are you just always testing new products that you think are the best? As of now, what system would you recommend to a DIYer with some tile experience to use for a walk in shower? You mentioned in this video how the tile redi system is good for DIYers, but I'm wondering why you wouldn't always use that? Is it a price difference for your clients? Thanks for the great and helpful videos!

[@smilesnow4593]

How does the Flox FX membrane compare to the Oatey liner?

[@DR-um2bv]

Was my question too. Looking like new fabric stuff is taking over. But how could fabric be better that vinyl. But was wondering how the vinyl could lay flat on floor for curbless shower and be able to tile over

[@jamalothmanRN]

[@eltonnoway7864]

Although not mentioned in this video, Isaac frequently mention in other videos his preferred thinset for this type of application is to use LATICRETE MULTIMAX LITE because it has a smooth creamy texture with no sand making it easy to spread and work with.

[@RhondaPerdew]

[@pigseye2]

Could you please tell us more about the crack isolation? What is the brand? Is it just a liquid or is it a liquid and a membrane? Thank you!

[@1bottlefed]

Did I miss the brand of thinset mortar? I am guessing its Versabond by Custom?

[@eltonnoway7864]

Versabond by Custom is good stuff but even though he doesn't mention it by name I don't think that's what hes using based on his other videos . In this video he mentions he doesn't use it for setting tile because its expensive. NOTE: Versabond only runs about $30 for a 50lb a bag whereas Laticrete Multimax Lite (that he promotes in a lot of his videos) runs $50 for a 25lb bag. FYI: Check out his video "Installing a FloFX Drain in a SCHLUTER KERDI FOAM PAN!!!" In that video he states: Laticrete Multimax Lite has no sand in it, its highly modified and Multimax Lite is what I use for all of my sheet membrane installations. Also... two other "hints" that its Multimax Lite... at 4:56 he states: "its so strong and so expensive... its hard to clean off your tools". BINGO: Multimax Lite is about twice the price of the more widely available thinsets from the big box stores... and no argument, even before it fully sets, cleaning Multimax off your hands and tools is a lot of work! Gets sticky!

[@DR-um2bv]

HEY Could a vinyl liner be used for curbless shower . & Will tile pop up where it ends and meet let's say crack protection mat. Since dry pack goes ontop of vinyl right?

[@rugerdogg5316]

I purchased densshield for my shower walls and ceiling . Should I tape and waterproof each seam and screw or will thinset over these areas be sufficient?

[@thetmyers3881]

Isaac , do you put the membrane over the foam shower pans , or can you ?

[@michaelhartman851]

In my opinion the waterproofing should be throughout the bathroom if it's curbless, the big problem that no contractors explain to customers is when you have a toilet backup it's going to flood the lowest points first, so the curbless shower makes a guaranteed flood any time the drain backs up even a little bit, which I've found almost none of my customers snake their drains preventatively they wait till the flood to fix the problem, pretty stupid if you ask me...

[@donniebrown4368]

Hello I'm Donnie and I really appreciate your video's. I have question about curbless showers. Do you have to have fall in the whole bathroom or just the shower itself? Thanks again Donnie

[@eltonnoway7864]

You would only need to concern yourself with "fall or slope" of the whole bathroom if you were building a "wet room" ...i.e., where the entire bathroom floor area is designed to be flooded with water or get wet. For example having a shower with no doors, walls or curtains and maybe a free standing soaker tub, and a drain located in the center of the room to catch all errant water so it will drain away. If your shower is its own area, contained with walls, partitions, doors etc, then you only have to address the fall or slope of the shower floor to insure it has adequate draining. In regards to a "curbless shower", as Isaac mentions in the comments: "Tile showers that have a curbless entrance need to have the waterproofing extended out 12" past the threshold of the shower." NET: The "sloped area" of your shower should start 1 foot outside the main shower floor area. Other than that the rest of your floor would be level and flat.

[@iFortold]

Looks like a lot of work, I'll stick to tile redi pans and goboard. Both of which are readily available.

[@eltonnoway7864]

True enough... as long as cost is not an option. GoBoard is three times the cost of cement board and a Tile Redi pan (with prices pushing $1000) is a whole lot more than a $10 bag of dry pack mortar.

[@Pepe-dq2ib]

@@eltonnoway7864 tile redi is clearly overpriced, but if you factor in the labor, it's not too bad. With Goboard, you have to factor in cement board and waterproof membrane or redguard. It comes out about even, but Goboard is quick and very hard to mess up.

[@stevemullen8457]

How do you water test a curbless shower?

[@eltonnoway7864]

By design, if the slope is correct (2% or 1/4" per foot) water will migrate to the drain. In a curbless with the drain plugged you simply fill the shower pan up to the point where it would be just short of overflowing into the bathroom. Granted, with a curbless system the water level might not be 2 or 3 inches deep like it might be in a curbed shower but that's not an issue. After filling the pan area, just measure the depth of the water over the drain at the start of your flood test and check it again in 24 hours. e.g. At start of testing, if you start measure 3/4" of water over the drain... and still have 3/4" of water 24 hours later... you're golden.

[@justinkulow7872]

Are you running the wp membrane around the room perimiter?? It doesn't take much for water to roll to the edge if the room....

Why can't you use an extra 4 inches of the floor membrane to put on the wall instead of the band?

[@Ryan-hu7or]

Hey coach can this be used with hydroban board?

[@ct9040]

Wouldn't sheet membrane first then bands and corners running on top of it be a better system? You mentioned it briefly. It might be easier ( nicer to your floor) if you do the corners and bands first, but that system seems like it could fail with all the gravity feed water running down the walls. Any thoughts??

[@eltonnoway7864]

I was wondering about that as well until I got found an answer. Check out KZbin content provider "Sal DiBlasi" and look for his video titled: "Shower waterproofing, step by step", once you find his video, jump to 34;46 where he goes into detail about what to do first.

What do you use on irregular angle corners that aren’t 90’s?

[@eltonnoway7864]

If you made a custom, non conforming angle then you will have to either piece-meal it or use a liquid water proofing membrane like Laticrete Hydro Ban

[@turboflush]

curious about the flood test on this? how?

[@EtreTocsin]

Wouldn’t it be better to add the banding then the corner pieces on top of the banding?

[@MakesCache]

I don't think they specify, only that you have 2" overlap or the like.

[@jefffarago8282]

I thought that non-mod thinset is used between 2 impervious layers because the mod thinset won't get enough air to dry/cure. Whereas the non-mod thinset uses the trapped moisture to cure. But you are using the mod-thinset to do the corners and the banding which is membrane on membrane??? Thanks

[@MakesCache]

The opposite, only use non modified if it's open to air. Like laying the tiles onto a water proof membrane. modified dries through chemical cure.

All of these companies will deny a claim if they find evidence you married, mixed or matched their product with another brand.

@tilecoach can you tile over tile.. I'm extremely concerned.. I don't have the money to hire another contractor to redo the shower.. I just hired a contractor and its costing me 12k to convert the tub into a shower and they used kerdi board and then "water proofed" it... the mosaic tiles on it look like a roller coaster and they are saying the mortar will fix it.. but I know its not pitched properly. 1 foot around the drain looks like a huge valley to where the drain is, but the drain is actually like 1/4 to 1/3 inch higher than the tiles.. and the floor mosaic tiles by the walls look like they are on angles.. They say I'm not a contractor and don't know what I'm talking about.. just to trust them which I don't.. I know they don't have 95% coverage behind the shower tile as I'm able to see behind it as well.. Not sure what to do.. I contacted another contractor who stated it would be 10-20k to redo the job. I wasn't sure if I could cover their floor tile and tile myself with a proper pitch to fix it? I have no idea what to do and a 10-15k job is now going to cost like 30k if I have to a pay a second contractor to redo the work of the first one who still hasn't finished.

The correct term is "linear foot." This term is used to measure length in a straight line. For example, if you are measuring the length of a piece of lumber, you would measure it in linear feet. "Lineal" is a term typically used in genealogical contexts to refer to direct descent or ancestry, such as in "lineal descendants." Therefore, when measuring length, "linear foot" is the appropriate term to use.
