Is my contractor right?
Comments (4)The floor drain should normally be centered to allow for symmetrical pitch on the floor. The valve assembly and shower head? It's part functional and part aesthetics. They don't necessarily have to be centered, but the shower head should at least be in a reasonable enough position so you're not banging your elbows on the wall when standing in the spray. The valve and head should be set so that they don't look awkward. If they are off by 1-2", it might be because there was a framing stud dead-center in the wall and they attached it to the side of that same stud.

Comments (1)I use one of the Delta combo heads. Large outer ring, smaller handheld in center. http://www.amazon.com/Faucet-58469-PK-In2ition-Shower-Chrome/dp/B006FYB4D2/ You can select center plus outer ring, or center only. Best shower head I've ever used, and it's not very expensive. (Mine looks like the one in the link, but was only around $75 at Lowes.)...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 Morestlouie
