I am planning on finishing a basement at a hunting property and really love the feature of steam shower like at my gym which can fit 5 people.

Anyone have one of these in their home or seen it done in person? I'm imagining it would be similar to building an enclosed shower space just with extra vapor barrier.

Thanks in advance for the insight.

It's the same EXACT thing, and the same techniques will apply.

The only difference is you want size/shape "X" instead of whatever everyone else has done.

I was thinking folding benches might work well. But I'm not sure if I should install permanent benches.

Also, I was planning on doing some sort of illumination wall using a stone or corian. Has anyone done that type of thing?

Never heard of em. :-)

Other than the sloping of the ceiling, the only other thing, and this one is much more important-- is that the entire room must be one giant membrane envelope, and it goes further than that-- it must be vapor proof, as well as waterproof. Most roll-on membranes (including my beloved Hydroban) require the use of an additional vapor barrier behind the cement board (either poly or tar paper), and in my way of thinking, that negates all the pluses of using a topical waterproofing. The only roll-on/ trowel-on membrane that has enough of a perm rating that it can be used alone is Hydroment's Ultraset urethane waterproofing, which is a trowel applied membrane. Hands down, the best membrane (for MY money) for a steam shower or steam room is Kerdi. In fact, I'm doing a steam shower right now and that's the membrane being used. It's even going in curbless.
