I went out to purchase a small lot of uncoupling membrane for a new series of test yesterday and stumbled upon Schluter System's new shower niche's on display. The shower niches are made from Kerdi Board and what looks like a type of silicone. I was surprised to see that Schluter did not think to design a slope into the niche. I think this is a huge oversight but something that can easily be fixed.
Just in case I was mistaken I used my wife's Air Miles Card to check to see if the niche had a slope.
This is a view of the back side. Total square to the Air Miles Card.
Inside of the niche. Again no slope here.
I do not like building any shower niche without a slope to the bottom. If I where to install one (No real chance of that happening since I do not work with foam based backer boards, curbs or shower pans) I would first make a little grade for the bottom. Most likely with some Ardex X32.
The instructions show just banding the face of the shower niche - the Kerdi Board Niche but I would wrap the face and bring it into the niche. I would not trust soley the silicone (if that is what it is) by itself at the face miter edge.
All in all they are a nice shape and size and will for sure save loads of time.
However I think this type of niche is a much better design and the same price.
This is a Private Label Niche. The sides and bottom are sloped so they can be installed any direction and have a sloped bottom. This is much smarter and a much better design. My camera died so I never finished getting some pictures. I'll snap a few next time I'm out in Burnaby.
UPDATE: In January 2014 I tested the Kerdi Board Shower Niche to see if it would hold water. It leaked day four. These niches are total crap. Jump to page six to see more.
