door-free shower; what kind of bathroom walls?
I am newly considering a tiled shower (instead of cultured granite/solid panels/etc). My tile-setter is very good, but I have no idea about the under-sides of tiling needs. I've been trying to do research and am getting a little lost in all the "right" ways to do things.
Anyway, for now a simple question--if we choose to do an open shower (no door), what kind of material needs to be used for the walls of the bathroom? Greenboard or regular sheetrock? (I am assuming more steam on the walls if no shower door).
As a bonus: if I go for a tiled shower floor (something I didn't think I'd do), how do I make sure I get a really great install so that I don't end up with a rotten huge structural beam underneath (second floor is held up by this beam).
My guy really likes to do mud pans. And, he said he could epoxy grout (spectralock) the base if I wanted to be really sure. He also has mentioned redguard, and liners. So, he may be more old school? He also said he really like wonderboard over hardi--and from what I've read, that is fine.
Any help is hugely appreciated. I have read through many old posts, including the one from Mongo where all the pictures on how to do a kerdi shower have disappeared but seems like it'd be a great tutorial...
