Water can leak at the transition piece going from the wall to the floor. It would be better to install the transition piece before the wall so it is overlapped from the top. Like doing shingles you want to do all u can to keep water on top. You would not install flashing on top of a shingle because it can leak even if sealant was applied. So why would you take the chance here. Have experienced leaks caused by doing this in this application already. On this video during water test that the thunder is already wicking the water. This is what causes water leaks later after tile install. Best solution I have found is to use a water proofing method over all joints prior to tile installation

[@jonathansuarez9990]

I was thinking the same exact thing

[@deflamrek]

Could you just roll the kerdi-membrane 2 inches over the floor too? or would that be too much material...?

[@traviswalker007]

over priced garbage IMO!!

[@nickschwab1063]

why is the long corners schluter put on prior to the wall? Will not the water go behind the tile seeping behind the bottom corner put on last. I have done this several times with this system and I still always put down in this order. Floor, corners and then the walls so there is no "natural drainage" down behind something. Or is there still a chance of capillary action ? I would like some feedback on this

[@schlutersystems1]

Hi Nick! When KERDI is installed with a 2" overlap, water will not be able to penetrate and cause any issues, regardless of the order in which the KERDI and KERDI-BAND are applied, whether "shingled" or not. Hope this helps!

[@buckmclean8391]

Why do people still torture themselves with these multi-step jigsaw puzzles? I have used several tile-ready custom fiberglass pans and wall panels. Whole thing goes in in a couple hours, and far fewer potential failure points. Kerdi seems laborious and archaic in comparison.

I have one of these and it is made out of foam..when it is laid down how does the foam not break to a persons weight ...and the foam curb looks like if some put any type of weight on it would break it I can only imaging a kid stepping on the curb

[@brotherbill1000]

Weird that they have you doing the wall first! As someone who has done a lot of roofing and almost every other home exterior, and for the past 15 years flooring and showers exclusively, I have to say that I always work from bottom up when waterproofing, meaning that I do the pan waterproofing then put the wall waterproofing on top of that, an would advise everyone to do the same. Never trust a joint lapped the wrong way to be water tight just because it is sealed, I don't care how much the overlap is.

[@TennantBuilds]

I’m of the same thought process… it does say that alternative methods may be used as long as the suggested installation method of the membrane is used…. Meaning v notch trowel etc etc…

[@JLFLC24]

First time I seen this video exactly my thoughts. Do floor first then continue with walls and overlap water proof membrane.

[@brianhegedus440]

I’ve installed everything and planning to do a water test tomorrow night but I just can’t understand one step and how it creates a waterproof barrier. When doing the shower pan I put in each of the corners. I’ve cut the Kerri band to put between but I don’t understand how it is waterproof without overlapping. Looks like there is a small gap between the corners and the band in your video. Is this correct? Aren’t those areas where water can travel? Do I need to overlap it or use the Kerdi caulk? There is thin set but that’s not waterproof.

[@schlutersystems1]

Hi Brian, all of the connections should have a minimum 2" overlap of Kerdi or Kerdi-Band. If you would like to talk through this installation please give our team a call at US:800-472-4588 or CA: 800-667-8746 they would be more than happy to discuss the details with you.

[@trollnapf1670]

Would it not make more sense to install the wall membranes last?

[@think41c]

Why use a butt-seam at 5:30 when you could just overlap the two full sheets of Kerdi-membrane like you did on the other wall? Are you just demonstrating the use of the band if for some reason it's impossible to just easily/simply overlap the full sheets upon one another and skip the whole need for the kerdi-band process?

[@schlutersystems1]

Hi there, yes, we are just showing the two options in this video. Since the KERDI-BAND is thinner than KERDI, the butt-joint method might be preferred when installing smaller tiles, such as mosaics, because there will be a little less build-up. Hope that helps!

[@amattson6578]

Why not overlap and join the seams together with kerdi band in a process that water never runs directly into a seam? For example..first membrane the shower pan. Then apply kerdi band and corners to the pan and wall board. Then membrane the wall over the kerdi band so the seams are never in direct contact with the direction of water flow. The schluter method is putting too much faith in the technology of how the kerdi band adheres to the membrane through the thinset during the curing process. This process could result in failure given the fact that thinset isnt waterproof and its possible theres not a 100% connection of the overlapping membranes. Installing it in the overlap method I stated in beginning of this post takes out any possibility of water flowing directly into any seam.

[@OriginalBabyBoi]

I was thinking the same exact thing. Wouldn't that be a safer way to go?

[@patrickwooten2649]

U are absolutely 💯 correct and Idk y shluter doesn't not apply the proper water shedding techniques and they need some kind of closed cell product to water proof 100% or it will leak after a few years this shit is crazy stupid and only a small amount of us have enough sense to see this.

[@nickroussain317]

so your saying do the shower pan first, connecting all the corners and membranes to the board then do the walls over that so the wall membrane is the “front” piece of membrane showing and not the corners? sorry just having trouble envisioning it. the way you stated makes more sense, no seam contact with water. just wanna clarify.

[@amattson6578]

@@nickroussain317 yes no direct seam contact. I call it the shingle method. Shingles overlap so water sheds over the shingles. Same principle here. Obviously the technology guarantees full waterproof either way but for me as the installer I like having extra piece of mind knowing that any water moving towards the drain will not run directly into a seam but rather flow over the seams since they overlap from the top down like shingles. Its still the same technology so the manufacturer should still warranty the product as long as youre still using the mortar they recommend and doing the manufacter recommended overlap which is usually like 2"

Because if the a schluter is installed properly, the drywall won’t get wet. I’d like to think this drywall is glued on this application but who knows

[@schlutersystems1]

Not to worry; drywall can be used because KERDI is a waterproofing membrane and will therefore not allow any water to penetrate and damage the drywall. We generally install drywall screws every 12" o.c., which is standard.

[@AmosMosesJr]

Schluter-Systems North America as a plumber things can and will go wrong. I've seen it. This is not a perfect world and I am not necessarily asserting that the Kerdi will fail. Other issues from behind the wall can cause water damage too. I am just saying it is an unwise practice if trying to save money. Plus depending on tile selection there will be a lot of weight hanging from those screws. Ordinary drywall screws are not known for their shear strength.

@@schlutersystems1 I will say this is an amazing product but it is scary what is being recommended to non-professionals who are probably doing this for their first time and don't know better. Some old time inspectors I know would not approve this despite your claims, and I don't blame them either.

@@AmosMosesJr We had this done in our walk in shower 11 years ago. Huge shower tiled to the ceiling. The shower had standard drywall screwed to the studs. No glue. We had zero issues.

Hi there! Yes, you can shorten each side of the shower tray. First, place your shower tray so it's aligned with the drain. To keep the perimeter height even on all sides, you will need first to cut 5" off both sides of the tray. Then, trim off and re-install the 1'' edge on both sides of the tray.

Schluter products are overrated and overpriced. Also followed mixture procedure of their All set cement and found out that the wall membrane did not adhere to the mold resistant drywall consistently.

[@ronquiring7796]

Water leaks are inevitable and evil. Why not reverse this process. Shower pan first, overlap with edge and corner treatment, then walls. Any flooring or walls will eventually flex and crack. Let the moisture barrier in behind overlap so beads of water will flow inward to the drain not outward to the studs. Think about how shingles and valleys are treated on your roof and duplicate the logic in your beautiful shower.

[@schlutersystems1]

With KERDI waterproofing membrane, the sequence of membrane installation can vary- what's important is that a minimum 2" (50 mm) overlap is maintained at all joints and proper connection to the KERDI-DRAIN is established. It doesn't actually matter which layer of KERDI goes down first in order for a waterproof seal to be made and continue to be water tight. So, although shingle lapping of the KERDI membrane isn't necessary, it is an acceptable option for any shower installation. 🍊

[@Lunaticked]

I just finished this install, this video is so misleading, that is not thinset they’re using, it looks like joint compound. Thinset is way harder to apply over a large wall area, so hard in fact I wish I never bought this stupid system. The stress trying to cover an entire wall and apply the membrane before the thinset starts to set was not worth the meager cost savings. The tray system is good, the wall membrane is horrible, don’t use it!

What's the reasoning for installing drain first with no access...I've installed many with no access AFTER pan was installed...just curious of that thought process

Hi there! The main reason for this is if there are different contractors on a project and the plumber comes through first and installs the drain flange. Then the tile installer would come after to install the tray and the rest of the shower component. Plumbers don't usually work with thin set, they won't install the shower tray. Hope that helps!

Hi there! Close, but not quite. 🙂 We are saying that all waterproofing connections with KERDI, KERDI-BAND, KERECK corners, and/or valve seals need a 2" overlap, however, the corners are longer than 2", so the KERDI-BAND can be brought back a little in that area so the strips don't overlap each other.

What is the difference between the but seem and the 2in over lap. I don’t understand why not just do the 2 in overlap like you did where the sheets meet.

[@schlutersystems1]

Hi there, Either way is fine. It generally just depends on user preference. Some like to overlap the KERDI as the go, whereas others prefer to butt join the KERDI and then cover with the KERDI-BAND. One practical reason for using the KERDI-BAND in some instances is when a small mosaic is being installed over the seam. Since the KERDI-BAND is thinner than KERDI, the build-up at the seam would be slightly less. Hope this helps!

Hi there, since KERDI-BAND is half the thickness of KERDI, covering a butt joint with KERDI-BAND will a be little less build-up than a lap seam, which may be helpful when installing small mosaics. Otherwise, either method may be used and it's just a matter of preference. Hope this helps!

[@pcskier3611]

Wouldn't it be better to install the floor pan first, and then the wall sheets with a 2" overlap on the floors, so any water getting behind tile would drain down and out over the overlap, rather than relying on the band joint? Or better yet, install the floor flush to the studs/bottom plate, then drywall, then Schluter wall sheets? Then do the corners, but none of the wall to floor banding? Would this be allowable if I choose to do it that way?

[@schlutersystems1]

Hi there ! There is no rules on what to install first as long as there is always a minimum overlap of 2'' of the Kerdi membrane. The Kerdi corners are a necessity thought as the band or overlapping won't waterproof the corners to 100%. Hope that helps

[@lovera3878]

Will this membrane accept heavy tiles. i plan to use durock for my walls for that purpose. is durock an overkill since the video depicts the use of regular drywell. Thanks

[@schlutersystems1]

Hi Carlos, yes, KERDI will hold heavy tiles. Regular drywall is all that is required beneath KERDI, however cement backer board and other solid backing materials (listed in our Shower Installation Handbook) are also acceptable. Here's our Shower Installation Handbook for reference: sccpublic.s3-external-1.amazonaws.com/sys-master/images/hd1/h93/9007208038430/Shower%20System%20Installation%20Handbook.pdf

@Pat Capo durarock?banding? Do you mean drywall mud and tape? Did you prime and seal as well as do a coat of acrylic paint,or better yet mold resistant drywall,mesh tape,and coat with rubber paint before the kerdi system? Edit: oh did you mean cement backer and mesh tape? I like to give that the same treatment as mold resistant drywall. I know you've probably finished your project by now,but ive made just about every mistake you can is all.

So I just want a regukar fiberglass pan…but tile walls. Can I still use Kerdi?

[@schlutersystems1]

You can use Kerdi on the walls for sure! We do have the Kerdi-Tubkit that includes everything but the shower tray and drain: www.schluter.com/schluter-us/en_US/Shower-System/Shower-%26-Tub-Kits/Schluter%C2%AE-KERDI-TUBKIT/p/KERDI_TUBKIT?facets=false

Trash bags and duct tape work the same

Where the drywall is beveled, you just level it under the membrane with extra thinset?

[@schlutersystems1]

Any minor differences can be addressed when setting the tile. :)

[@derekotto3636]

Why not start with the pan and then transitions? Shingle effect working up to the walls.

[@schlutersystems1]

Hi Derek, Either way works as long as there is a 2" overlap 🍊

[@Stevenyoung100]

So are they just randomly adding a butt joint by choice and then not explaining why they're doing that? I don't get it they could have just easily overlapped it and not have had to put the overlayment in extra mud.

[@schlutersystems1]

Hi Steven. The reason we are showing the butt joint with KERDI-BAND over it is that there are a couple of situations where this method would be preferred over the overlap method. The main reason is that the KERDI-BAND is thinner than the KERDI membrane, so a seam like this would be beneficial in reducing build-up for cases where smaller tiles, such as mosaics are used. Another reason for using a butt joint could be if that layout works better to reduce the total with of the KERDI membrane used by maybe 6"-8" in some showers. This could come in handy if there is more KERDI-BAND on hand than there is KERDI membrane. Either way, we like to show all of the options so you can choose what works best for you in each application.

[@melvinosorto2575]

My question is is mortar waterproof, can the water go through the thinset?

[@schlutersystems1]

Hi Melvin! Good question! The thin set mortar is not waterproof. If the water penetrates the grout and get's to the thin set it will reach the KERDI membrane and go no further. And then eventually, it just evaporates back out through the grout lines. No worries!

[@davez2989]

I don't understand why all the parts that get applied in an order that seems to be backwards. If water were to get under any part it will stay under forever. you example starts from the top down basically. Why don't you start at the drain and work your way up installed the pieces so the higher pieces fall on top of the next going down.

[@schlutersystems1]

Hi Dave! The sequence of membrane installation can vary provided that a minimum 2" (50 mm) overlap is maintained at all joints and proper connection to the KERDI-DRAIN is established. Also, top-over-bottom or shingle laps of the membrane are not required. So, It does not matter which layer of KERDI goes down first in order for a waterproof seal to be made.

[@ceeIoc]

Before you lay down the tray, do you need to seal the bottom of the keri board wall with kerdi fix?

[@schlutersystems1]

You can seal all seams and joints after installing the tray. This excerpt is from our handbook: Seal inside corners by abutting adjacent sheets and installing KERDI-BAND with Schluter SET®, ALL-SET®, FAST-SET®, or unmodified thin-set mortar, centered over the joint. Install KERDIKERECK prefabricated waterproofing corners at all inside and outside corners. When using the KERDI-BOARD-SC curb, seal the curb to the base and walls using KERDI-KERECK and KERDI-BAND

[@AlanSmith-q7r]

What would you put?

[@codypridg9504]

Why would tar paper not work the same?

[@schlutersystems1]

Tar paper is not recommended to use in conjunction with the Schluter Shower System. Just like a traditional PVC or rubber liner installation, there may be alternatives to using the Schluter Shower System. Differing installation methods should not be combined with our system to create a hybrid system. Schluter Shower Systems are an integrated family of products and are designed and engineered specifically to work cohesively to create a sealed system. Hope this helps!

[@ceeIoc]

Can I install the shower tray directly on concrete the same way as shown in the video, with thinset?

[@schlutersystems1]

Hi Ceeloc, yes, you can install the tray over concrete with Schluter-SET, Schluter-ALL-SET, Schluter-FAST-SET, or unmodified thin-set mortar.

[@jdmferio08]

Could u do the shower pan before putting membrane on walls ?

[@schlutersystems1]

Hi! Yes you could install the shower tray first. As long as the 2'' overlap is achieved at every seams, with KERDI or KERDI-BAND, the order of wall and floor installation doesn't matter. Hope that helps!

[@brettbrani1716]

Can I ask why you would use corner and seems on the outside and not the inside?

[@schlutersystems1]

Hi there. Since KERDI membrane is installed over the solid backing down to the subfloor and the provided shower tray is waterproof, the seams of the outside perimeter and corner seams of the shower tray must be sealed to create a fully waterproof and vapor tight enclosure. By installing the KERDI-BAND and KERDI-KERECK inside corners over the pre-sloped shower tray, these components prevent moisture disseminating below the top of the tray; therefore, installing the KERDI-BAND and KERDI-KERECK corners underneath the tray is not necessary as moisture will not travel to the substrate. Hope that helps!

[@Stevenyoung100]

Is the bonding flange on the drain installed without PVC glue?

[@schlutersystems1]

Hi Steven, the flange outlet is connected to the drain pipe with either PVC or ABS glue, depending on which pipe material and corresponding drain you are using. The reason we don't show that in this video is because there is access below to connect the drain later. Here is different video which shows you the gluing process for a no access installation: kzbin.info/www/bejne/q169en-PfriYjpo Hope this helps!

[@Ramdinohikes]

Can I install without pan and use the wall membrane instead for the bottom of the shower and then use grout to slope to the drain?

[@schlutersystems1]

Hi there! Apologies for the delay... The options for sloping a tiled shower floor to the drain are a KERDI-SHOWER-TRAY or a Portland cement mortar bed. The sloped mortar bed would need to be installed prior to the KERDI membrane so it wall be waterproofed on top and the water would slope to the drain and not saturate the mortar bed. The KERDI on top of the mortar bed would also continue up the walls in accordance with our Shower Systems Installation Handbook to create a completely waterproofed and properly sloped installation from the shower head to the drain. Neither grout or thin-set would be appropriate materials for creating a slope for the shower floor. Here's a link the handbook: sccpublic.s3-external-1.amazonaws.com/sys-master/images/hd1/h93/9007208038430/Shower%20System%20Installation%20Handbook.pdf

I have a odd shaped wLk in shower, one valley is at a 45 degree angle. For the part of the shower are that has the angle wall, could I use a shower pan, say 48 x 48, trim to size to fit, and cut off one corner of the pan to fit the angled wall? Then for the flood where I walk into the shower, could I Juilliard the floor height up to the shower pan height by using plywood Then cement boars, and cover the cement board with Kerdi and seal the Kerri to the shower pan? Do that instead of building floor up with mortar?

[@michaelbarnes5636]

Is the curb sloped as to drain water back into the shower pan?

[@schlutersystems1]

Good question! The curb itself is not sloped. When you are setting tile on the curb, the tile must be sloped towards the shower drain using a little extra thin-set under the tile on the further edge from the drain. Hope this helps!

[@justing5477]

You should have the installer put 2x4 behind the curb when first installed to help keep it in place with a couple screws

Rather than replacing all of the tile work in the entire shower, can I demo and replace the pan, remove two feet of the old travertine and shingle the new Kerdi a few inches above and behind the old shower wall base?
