SCHLUTER KERDI SHOWER KIT - TUTORIAL (LIFETIME WARRANTY)

Schluter Systems Kerdi Shower Kit is one of the most popular ways to prepare and waterproof a shower for tile installation. Using a foam shower pan tray, membrane, foam curb, preformed niche, and triangular foam curb I show how to properly install the components to achieve a lifetime warranty. This was the first time I have installed a schluter kerdi shower kit using ALL-SET thinset mortar. This specialized, modified thinset mortar dries without the presence of air to cure it, making it great for in between layers of waterproofing. This is the only way to achieve a lifetime warranty using Schluter Kerdi systems.

Cool story about Schluter: I called the store where I bought some pebble mosaic for our shower floor. No spec sheet so just wanted to see what trowel size they recommended. A “manager” ended up taking my call and told me I should really have a professional do the install. “Lady, I took work off tomorrow to lay this floor. I called to talk to someone competent, not be told I can’t do it.” Then I remembered I had the regional Schluter guy’s number. Texted him and got a response within 5 minutes. Not only that but he said he happened to be in town and could swing by tomorrow to show me a knockdown method that’s helpful for laying pebble mosaic. This guy showed up, showed how to mix All Set, gave me a trowel to keep, some tshirts, a hat, profile gauge, etc. Even gave me a seal I still needed to pick up. Outstanding!

Pebbles on a foam pan😬

[@JaykUS354]

Cody, I thought the same thing but the newer pans hold up just fine. Maybe not the first ones they came out with so much. Also, using pretty much flat cut so no worries at all. You’re right maybe actual river rock could be worrisome because of pressure points.

[@codyrobison6817]

@Matt The Builder. I understand how they work I build showers everyday theres a thing called load point I've tore out plenty of foam pans with penny rounds and even a couple with river rock that's why I said somthing tile work and shower work isnt a race so to build a whole bathroom in 2 hours means nothing to me

[@TileCoach]

Foam pans are really sketchy for small tile like pebbles. May work, but if a ladder gets placed on the edge of one, or a lady in high heels (you never know) tiles will punch through the foam . Not sure you noticed but we we did a large format with a envelope cut on this one. Stay tuned for that video! Love the discussions guys and thank you for keeping it civil.

[@codyrobison6817]

@Matt The Builder. I would care less about a day less honestly I build my pans out of deck mud and can GARENTEE you theres no issues with load points the tile game isnt a race in my oppinion it's about quality and a long lasting job that's never going to fail I would never use pebbles penny rounds or anything smaller than a 2x2 on any foam pan its foam dude dont care how strong you think the pans are what if someone puts a ladder on it when your not there that's just asking for a failure then who has to fix it you do. Another thing is the subfloor has to be perfectly level to use those pans which is hardly ever the case there is to many variables that come into play when using foam when a deck mud pan is much much better

I would wrap the corners of the pan before adding the angle bench seat to prevent any leakage. I like how you decided to lay on top of the shower pan instead of cutting back the pan.

Best way tile walls n shower pan then do the corner bench on top of tile

[@cohenkevinloriqueen818]

@@marcopoulin1897interesting.. I’m getting ready to do this exact same layout in my shower at home.. why tile all first before the bench ?

[@JB-wx1mz]

I have done these a few times, one trick I like is cut off an extra 2" then take your scrap and cut 2" off that, then put the 2" scrap piece against the wall for a nice flat perimeter. Eliminates the bowl effect at the edges. Sheet membrane over top.

[@ImmortalWrekcage]

Going to be doing my shower here in the next month. Wish me luck. I am planning on using the kerdi kit because making my own pan seems out of my comfort zone.

[@seanmellows1348]

I’ve done several dozen of these at minimum, and I approve of this. I like a lower, narrower curb, I use k-board for custom specs. Often as narrow as 7 cm. And 7-10 cm high. I always float over the finished pan with at least a skim. You can use a small notch over that and fill next day to make pressure point resistant under smaller mosaic, but for 2” just a skim is sufficient. Thanks

[@LosDog14]

The most time consuming process. I still use this system but I'm getting my company to switch. I had a Schluter rep do a demo shower in our show room. You cannot avoid the buildup of fabric over fabric. I had to shave and thin out the back of the tile to get it to look decent.

Do the tile first and then silicone the foam bench in. You can use foam sheets and silicone them together to get your height. Then silicone underlayment to it and tile. Then if your bench fails it fails inside the shower and goes into the pan.

[@markgrumke2193]

Loved the shared details on types of mortar, trowels etc. 2 questions, what is a reasonable post mix "bucket time" for the mortar used in this video?

Schluter makes modified (all set) and unmodified (set). They specifically market Set for adhering membranes, and All set for over and under membranes and setting tile. The marketing material I read doesn’t differentiate when to use one or the other.

If you hadn’t trimmed the bottom of the bench, it would have had the same slope as the floor (which could be a good thing). It might have been better to trim the vertical pieces, but maybe the build-up from thin set is Shluter’s reason for recommending it there.

Thanks for all your videos Isaac! I’m looking into remodeling a bathroom and I’m curious, how do you decide between using a kerdi kit like this or floating the pan like I see in a lot of your videos? I’ve been planning on floating it as you make it look so doable, but I’m curious to know how you decide between different approaches!

[@tileguru7807]

I see that you've not received a reply. The difference between using the foam pan from a mud bed is in your skill level. If you've never done a mud bed before you'll probably struggle with it and be better off doing the foam pan. If you're good with your hands you can most likely pull it off, but if you're newer to this and aren't used to the tools, or unsure when the mud is mixed correctly, you're going to wish you had used the foam. Pro's who do this for a living have likely done hundreds of showers and therefore make it look doable by anyone. Don't be deceived by the ease of which it looks. In my 35 plus years of experience the industry has changed dramatically, more so in the last decade than in the previous 5. Do it yourself shows and do it centers have driven the shift to do-it-yourselfer products which require less skill but generally deliver a more difficult or poorer installation. If you've never done this before it would be far better to hire a pro, but if your confident you can succeed then by all means give it a shot - the mud pan with Kerdi membrane over it is the better product. I don't however recommend the Kerdi drain. I prefer the flofx drain. Wish you the best!

[@frankgorgone6679]

I agree with everything the tile guru said. The one important thing he left out is that if you are going to use a foam pan! YOUR FLOOR MUST BE PERFECTLY LEVEL! If it is not you can have pooling and as we all know that’s failure just waiting to happen.

[@LosDog14]

I love what the Schluter Shower System does. I'm just tired of using it. Way too many steps and fabric over fabric = bumps period.

[@mrunner7671]

I am going to tackle a shower renovation at home and use the Schluter Kerdi Board. I have a few questions I was hoping you could answer. I was thinking of using the Schluter Dilex AHK in the corners and along the floor where the wall tile meets the shower floor tile. Would that work since it is made of aluminum? Also, after installing the Schluter shower pan, do you tile the walls first or the shower floor first?

[@mikesacco8457]

I have a ton of calls this year about this kind of install. They were done correctly but didn’t hold up. I just can’t agree it’s a great product. I do have customers who want this and I put my 2 cents in. But when I do my install I always run wires in key areas so I can come back 6 months 1 year later and check with a meter so I can see if anything is leaking. 1 area always do inside is the bench. I’ll admit a few guys I know are scared to run wire because if they check it and there’s water then there on the hook.

Question on overlapping the kerdi band to seams....it seems it would be better to first kerdi membrane the pan, then overlap band and corners to the pan and wall board, then last apply kerdi wall membrane and overlap that over the kerdi band at pan perimeter. This way everything is overlapped in a way that water never flows directly into a seam. I dont get why they seam together the membrane in a way where water directly flows towards a seam joint. I get the technology of kerdi how in bonds between thinset during the curing process but its too risky for me considering thinset isnt waterproof.

You talked about Schluter using modified thinset but Doesn't Schluter specifically recommend unmodified thin set for kerdi membrane?

They say to use one of their three products (which includes "All-Set" which is in fact "modified") OR "an un-modified thin-set". So basically they are saying only THEIR modified stuff is good to use right? If lets say I was not interested in keeping the warranty, then other manufacturers modified thin-set should probably be fine?

Is this something specific for Kerdi board? I did my bathroom 15 years ago with an 1/8 in notch to cement board and I have had no problems since install, with water or anything. I also didn't do any of the fancy water proofing paint. That's the way I was taught in the 90's to do showers.

You can use any type of Sheetrock. If it makes you feel better you can use moisture resistant gypsum. The membrane is waterproof

OK , I'M A DIY'ER I'm going to be installing the rubber membrain method i like your videos i will be going on a wood floor can i put the wet mortar on the floor or I seen it you put roofing paper down first I have watched some of the other videos (starr tile) which he puts the Oatey down flat with no slope i only want to do this one time ,

[@cohenkevinloriqueen818]

Slope it !! Unless you like smelly water

[@ExtremeRecluse]

Stores don't sell the 5/8 Green Board. Only 1/2 inch.

[@davidbenson1112]

Can you use half inch kerdi board on walls then membrain over that?

[@aaronkhachigian409]

I'm no pro, but all the research I've done, which has been a lot. The kerdi boards already have the waterproof on them. No need to apply another layer of membrane.

I have the same system and putting aqua-defense on top of it. I understand it ruins the warranty but I am afraid I will have pinholes. What do you think of that idea? Do u think it will help?

[@michaelreilly3347]

I have seen a lot of people doing it with various products (including Tile Coach). My opinion, if you don't trust the system without adding something else then you probably should not use it. Secondly, I can't think of any situation where two layers of waterproofing is a good idea...it will always result in a mildew/mold sandwich.

[@jbrenes615]

Hey tile coach I have watched a lot of your videos and they are very informative. But I do notice you have been trying out a lot of different systems. Which to me seems confusing on which system is actually the best. So in a nut shell please let us know thus far of all the different shower systems out there which one do you prefer best and which one you would use in your own home when doing a complete tiled shower. I’m sure at some point you will turn to a go to system based on ease of installation and long term leak proof system. Thanks

By showing all systems, he is teaching for all who have bought into a different system.

@tilecoach, this is an excellent question. Can you please answer?

[@DeLuca101]

These systems all suck! They aren't built to stand the test of time. Especially wedi

I am installing my first Schluter Shower kit and it is an 38" x 60" offset. The plumber roughed in the drain in the concrete slab too close to the wall. It is approximately 4.5 inches from the center of the drain hole of the foam floor from Schluter. The only options I can think of are to dig out the concrete and add a fitting to create the right angle or to build a small platform to do the same thing. Is there any advice on the best way to do this? Or do I scrap the Schluter system and figure out how to form a shower floor from scratch? I am not a professional, but an experienced DIYer, (I know that is not a word). Thanks

[@michaelreilly3347]

You do not say which direction the hole is off. If it is still centered in the 38" width but is 4.5 inches too close to the plumbing wall, for example, you can cut the 4.5" off that end of the foam pan, set it over the drain location per instructions and then fill the remaining gap on the other end of the foam pan with dry-pack or concrete. In my case my shower was 6" longer than the foam pan to begin with so I took a scrap piece of the 1/2" foam I used on the walls and set it in thin-set to match the slope of the pan and sealed it together with banding. If however your misalignment puts it out of alignment with the wall fixtures etc...you may want to relocate the drain as you say.

[@homerscustoms7635]

did you even glue the drain to the pipe

[@jtltet]

Does the Kerdi Foam Pan have a weight limit?

[@michaelreilly3347]

I have a shower built 2 years ago with the foam pan from Schluter. I used 2" octagon tiles and have had 4 adults using it on a daily basis. One of said adults is just shy of 400 lbs. The joists in the room were all sistered for additional support and the subfloor is 3/4 plywood glued and screwed. I have had zero issue with any of the tile or grout joints cracking however I am seeing the caulk around the edges starting to degrade.
