I once stayed in a hotel where the bathroom was one big open room, with a slightly slanted floor. The shower nozzle stuck out of the one wall, but the entire bathroom was the shower. The whole room was tiled. It was awesome. Someday I would love to build a bathroom just like that.
I can't stand glass doors. It's too hard to remove built up soap scum unless you (or previous residents) have been cleaning them regularly. We currently have glass doors in our condo right now. The condo is 25+ years old and it looks like no one has ever seriously tried to clean off the soap scum I've tried everything at this point. I'd rather have a plastic shower curtain liner that I can replace every few months.
I have a plasticy curtain that goes on the inside, but the outside is a decorative one with pearls, rhinestones & that feather boa material. Very cute. It matches the theme of my bathroom & has little dresses and lipsticks on it & says stuff, but I can't think of what it says! LOL. Funny because I was literally just in there showering less than 10 minutes ago. I think it says "Some Like It Hot" and other foxy-ish stuff. Lol. I love decorations . . . and rhinestones & pearls! & it happened to match my theme perfectly.
For decor I'd prefer some type of cool looking plastic or cloth curtain, but those tend to be annoying to me. We have two bathrooms, an upstairs and downstairs. The downstairs has glass sliding doors, which I prefer because they don't stick to me while I shower. The one upstairs has plastic on the inside with a nice cloth on the outside, but it's annoying. The tub/shower is entirely too small for me to have them and I wish we could replace them with sliding doors too. I'm a tiny person, but because I have shoulder issues, I have to maneuver in a wide area especially for hair washing, so it can be a pain when my arms stick to the plastic. It's not that it really does anything other that just irritate me to have that feeling, but I just don't like it. At my old house, we had a much wider tub, so I didn't mind the plastic liner then.
