I just put in 1" square tile mosaic. I called Schluter about it they said to skim coat the base first let it dry then install tile. Worked fine it has been in for about 2 months now no problems. I always call Schluter tech support when I am doing something new with there products. They always have more advice then is sent in the manuals.
He forgot to embed the shwr tray properly to a level substrate.....dumbass. This system is bulletproof. You can use whatever tile size you like and then just make sure you use an unmodified adhesive or it will never dry .
I think it's bending more because there is quite a large chunk of the tray cut out and he's standing right on the edge which is cut obviously it would be weaker there

@deddsexy Sorry Sir, but you too are wrong. The pan is pourous and so is the wood substrate he is cementing it to. A latex modified thinset would have plenty of opportunity to dry properly. Have you given any thought to the fact that the pan from Schluter is made from only a 2 lb eps? There are several other manufacturers who make the same pan in a 3 lb format that you can park a truck on. Schluter makes some great products, but they are certainly not the end all, be all.
There appears to be no Schluter Kerdi waterproofing membrane over the tray. I have never used the shower tray my self but have only heard good reviews when installed correctly. It appears that it sustained water damage from improper installation.
Even if a mortar bed was used instead of the shower tray the wood under that would have rotted out from water damage due to incorrect installation. It may have lasted longer but would have had the same outcome in the end. Do it right the first time.
That was my fear with going with the styrofoam tray when I consulted Schluter. I never got a satisfactory answer, however, they did answer by sending me tech spec sheet. My tray option was Custom mortar bed/kerdi, or manufactured tray. I went with Manufactured tray. My friend had his done using the shower tray kit, and everything perfect thus far. However, he did have his installer take care of floor and checking structural soundness.
I say ccaron is the idiot ,as previously posted BAD installation worng mortar.. if the sub floor is wrong or incorrect then everything above it is going to fail.... leave tiling to the pro's obviously your not one
@FireAce44 What is Schluters mininum size suggested? I've installed maybe 30 of these over the past 6-7 years, some with 1/2" mosaics, some with 4" X 4", (The largest I wish to use due to loosing some of the slope because the tiles are so big) Most popular is the 2" X 2", but even with the 1/2" X 1/2" jobs Ive completed, some now years old, Ive never heard report of any problems.
@vpbubbies I thought it was 1", but dont write it in stone. What just made me mad about my last tray is, I had to tile to the ceiling, so I had a 3' ladder standing on the installed pan (no tile yet) and I had to level out 4 huge holes from the ladder. Kinda disappointing, but I have never had a problem after the tile install.
When it comes to things like painting or maybe a bit of drywalling or lino sure do it yourself. I am a tile installer and it blows my mind how many people I have come across that have done there own tile work and I've had to go fix it for them. When it comes to certain things you should leave it to the professional.
@boraboy4ever You're spot on. The floor appears to be "Oil canning" probably warp from a leaking drain before and was never properly supported. And you're correct, ANY material would weaken after being subjected to continuous compression. Taking an impact hammer to the tile aint to bright either.
The pan made of expanded foam has a compressive strength of only 57psi (FAQ on Schluter website).
Standing on one's heel on a 1-inch mosaic, wearing only a sock, one's entire weight is concentrated on one square inch. If the guy weighs 200 pounds, say, he's subjecting the pan to almost four times more weight than it is designed to hold. At that weight, a 2" mosaic would be borderline spec. A 3" tile would spread the 200 pounds over 9 square inches.
This is a German engineered product and, well, the Germans are not as quite as "large" as North Americans. Perhaps Schluter needs to put ratings on their pans, like ladders have. =P
Seriously, something is amiss in the installation. I'd say subfloor or pan adhesion error. Perhaps something really heavy was dropped in the pan area? (The installer's Wife?)
Come on, I can make any tile job fail with a hammer!
hey stoop. don't go saying glass in unmodified as a rule. not so. each manufacturer specs can vary. only thing that is standard with glass is whitethinset.
I just installed this system for the first time. Although there is some flex, its nowhere near what this video shows. Something else is amiss. Also, dont go smaller then 4" tile and you will be fine
I wouldnt use it just for this reason , it compresses, there's alot of money to be made in time saving products, and I dont believe the consulted installers get the final say as to whether or not products go to market. I see no subfloor movement , i see compression
I have emailed the video to schluter. I have never seen or heard of this happening...regardless of tile size. It looks like his subfloor is moving vs the shower pan compressing
@ccaron14 sorry bud you ARE wrong. when useing the tray you cant go any smaller than 1 1/2x 1 1/2. if you want to use a smaller tile do a cement base. call schluter systems they will tell you the same thing. I have done countless showers I have never have had failure.

Bad installation, the WRONG mortar, and the glass mosaic is too small, Shluter has a limit on mosaic tile on this floor.
As said before, I see a bad installation. Do the world a favor and dont show off your messed up projects. Nice socks though

glass tile = unmodified mortar
kerdi = premium unmodified mortar
tray is a polyethelene product, not a flexible material. Installer doesn't know basics of tile setting, leading to failure.

the floor may not have been level before he started, if there's a high or low spot, sure the tray is going to flex.

Schluter doesn't have a tile size requirement on the tray, the "no tile smaller then 2x2" requirement is on Ditra, not the Kerdi tray.
Ditra:
Limitations
minimum 2"x 2" (50mm x 50mm) tile

Did you use premixed mastic or did you use thinset mortar?
rebelyellow12345 3 years ago
Where I live, you can't use 1x1 tile on the floor according to the building inspector, so we didn't.
I just think that the subfloor may not have been properly prepared prior to installation, that's why there is a weekness in the floor.
hapa642002 3 years ago
no doubt, the tray itself doesn't actually compress, so there's some play in between the tray and the floor or the floor.

I have emailed the video to schluter. I have never seen or heard of this happening...regardless of tile size. It looks like his subfloor is moving vs the shower pan compressing

Who's the idiot? It's 3/4" tile which according to Schluter is OK. In fact, they don't have a minimum size recommendation.
