The unit is a Steam Mist SM-11 with auto flush. So its a pretty good unit and I am able to get to and maintain the max temp the unit can do, so I think we are sized properly... the problem I am have it one of physics; hot air/steam rises, cold air/steam sinks. I don't see how this could be over come apart from a mechanical means. Just look at a steam unit, there is only one thermostat per shower and the air above must be hotter, the air below it must be colder.

Hi Jo Ann, I just had a shower finished with a 14' deep bench. Plenty of room for me to stand on it while cleaning the walls :) I just can't imagine one reason why I'd sit on it..... Anyway, the advice I was given about a corner bench was to keep the construction closed vice open under the bench because it would be a mildew nook. I hope I explained that right. I have pictures posted of the shower bench on this forum, just search on my user name, it's labeled marble and subway tile shower pics or something like that. Maybe it will help you to have a visual of the depth. Good luck!

Is there a specific slope for ceiling or just enough so water will run down sides? 2" per running foot, but it doesn't all have to be in one direction. I've done steam showers and rooms before that pitched from the center to both sides (kind of like the roof pitch on a house) and I've done one where it went from a centerpoint, and pitched to all FOUR sides. any specific type of tile to stay away from? natural stone. Other than that, while porcelain will most often be recommended due to it's almost nonexistent absorbsion rating, any kind of ceramic tile will work. Also has anyone used glass block? You really shouldn't being that there's no way to waterproof that wall (the mortar joints would not be watertight, nor would it be where the glass block hits other surfaces) as I only have one window that opens. While opening windows are discouraged in conventional showers, they're considered a no go in a steam shower, due to the fact that there's way too much chance for water intrusion into the wall. I've done one steam shower where there was a fixed window, and even that was covered in Interlux boat paint to make sure it was waterproof. Then, both the Kerdi membrane directly under the tile, as well as the tile itself was sealed to the painted surface.

Even with sealing the grout on my ceramic tile shower walls (NOT a steam shower) I can't keep the mold from developing on the wall grout. Even with a better exhaust fan installed, that runs 1/2 hour after the shower on a timer. Even with an HRV running in the house. We are in the humid southeast and that apparently is a challenge for all materials, machinery, and installations. I have a solution, but you wouldn't want it. I'd just say, you won't really know till you live with it. Other people's experiences might not be the same as yours--conditions always differing. So, be prepared to live with whatever happens and just minimize your odds as best you can of having a miserable situation to contend with. And/or have an exit strategy if you find it too miserable.
