I’m sure a pro will weigh in, but I can tell you that our ceiling slopes 2” per linear foot towards the back wall of the shower. But I’m concerned that maybe your tile professional doesn’t know how to build a steam shower based on what he’s saying to you. Our tiles are 12” x 24” and they were installed one row at a time over about 4 days and supported by poles for a few days. Steam showers are special and require an expert tile pro. Probably you should pause for a meeting. Confirm the vapor proofing that was done and what the tilling plan is for the ceiling. Something seems off. I can’t tell what your pictures show; can you post some better ones? I’m not a pro. Hopefully one will weigh in.

I think the shower head you've selected is not appropriate for this application. I suggest a rain shower head with a shower arm to avoid interference with the sloped ceiling.

This is in no way a steam shower install and you better stop now anf get someone who knows how to build one. This whole space needs to be completely waterproof I don’t see the shower head but that is the least of the issues . If this is to be satem shower begin again.

Hi Charles - thanks for sharing your thoughts but I can’t really change the shower head now. It was a major investment and wifey loved it (I did too a little).

This is a pic of the shower head.lm covered in cardboard.

Thanks

Hi everyone thanks for sharing your very helpful thoughts. They used orange schluter kerdi board (pic below) everywhere inside the shower. They then added mud on the ceiling that covered it up (not sure why - level?)

One thing that bothers me is that they added these 2 inch screws to hold up the tile and I thought that was weird. Those screws must be penetrating the vapor barrier, no?

I can’t change the shower head.

Is this orange board okay?

What to do at this point? I think they need to replace the kerdi board that’s penetrated. But then again, how to tile it while maintaining a 2” slope per foot? Should they tile from the shower head away to the surrounding margins of the shower?

Thanks!

Kerdi does not meet the steam shower vapor proofing requirement of .5 perms or less Kerdi is 8-mil thick and has a water vapor perm of 0.90 perm when tested according to ASTM E96. Penetrations into that membrane create further issues. That is not an acceptable method of creating the required ceiling slope. It’s like they forgot that needed to happen during the framing stage. This will have issues with moisture vapor passing through and condensing behind your walls. It is a redo. With a different, more knowledgeable, tile professional.
