okay for curbless shower to use a shower pan with regular drain?
Comments (8)With a curbless shower, I see two issues you may be facing. If he is planning on using a traditional rubber liner, a pre-slope under the liner is required. This slope is a minimum if 1/4" per foot from the drain to the farthest wall. In this case, I assume that to be the entry. I fugure that to be about 2 3/4" higher at the entry than at the drain. The rubber or vinyl liner sits on this and a FINAL mudbed is then formed over the liner. As you can see, there will be issues with no curb and how you'll terminate the slope to a feather edge at the entry. I don't see how that can be done. The other issue is with the liner itself. I see no way to attach it to a mudbed that would have to end at a feather edge. These liners are designed to go UP the vertical walls about 6-8" and nailed into place. Having built these before, scrap the liner and use the Kerdi. It's a bulletproof install, you only need ONE mudbed as the material is bonded directly to the mud and you can generally extend the Kerdi six or eight inches into the bathroom for a bit more insurance. On one hand, yes...it's a bit more cost, but realistically, it's also a shower you'll probably never need to repair or replace. The Kerdi is under $1.40 sq/ft. Their drain will run about a hundred bucks. On the other hand, you only have the cost of one mudbed, you eleminate the vinyl liner, as Kerdi is completely waterproof, you can save by using standard drywall in the shower as opposed to cement board. This is what Schluter recommends. Bottom line is that you'll pay a little more but get a far superior shower. If your tile installer isn't comfortable or familiar with Kerdi, find one that is.

Comments (2)That's what it probably is...3/16". Only thing I can think of is to put the thinset down very generously to give myself 1/16" or 1/8". I certainly down want the drain sticking up....See MoreKerdi shower pan - drain not centered; is it really a problem?
Comments (8)Thanks Mongo, You've made my night! I was awake until 1:00 this morning, going around in circles in my head planning my tile layout and how to best deal with the drain, so I'm happy this idea is sound. I actually was considering your second suggestion of floating the tiles up a bit to get a better match, but I like your suggestion of feathering out the thinset below the membrane. I have a hard enough time with the thinset squeezing out with mosaics. I don't need to make it even harder on myself. Now that that is figured out, I'm sure I'll find many other things to obsess about in the three weeks until we have time to do this project! Actually, I do have one other question (for now!): the shower will have two full walls and two curbs at right angles. I have two Kerdi curbs (the gray ones that are reinforced inside) and felt fine about those until I saw someone on a forum somewhere worrying about whether those would be able to support their frameless glass walls. We are planning frameless glass walls too, so I started researching that and couldn't find anyone who had actually talked about combining the two. Kerdi says they are strong enough (and I have an email in to the glass dealer to check), but just wondering if anyone has actual experience putting frameless glass walls on the Kerdi curbs? I checked the glass doors/walls we're getting and it looks like most of the support will come from the anchors set into the walls and there aren't any holes that need to be drilled into the curb (the walls rest on silicone shims), so it seems like it should be fine?...See MoreSchulter kerdi shower drain too tall, help!
Comments (5)Tundra- the answer to my inquiry might help the original poster as well. I don't want to divert this thread from the main question of the shower drain height but I have questions related to Schulter systems...and it seems the original poster might encounter similar issues. .. We're using a contractor's plumber to install a Schulter system and he's installed many of them. I wonder about the flood test you mentioned . Is that the overnight test to check for leaks? I was assured that " this isn't necesssry" and there is "no leaking" with Schiller unless the tile guy messes up. Should I be concerned? Insist on a flood test- if it is what I assume it is? ....See Morebill_vincent
