You wouldn't want the walls to get all mildewy from the moisture now would you?
When you need a room that does one thing and does it right.
Always make sure someone is around when you're taking a bath so you don't accidentally drown.
Sure, I'd love to knowingly trap myself in a plastic bubble full of many many gallons of water within which I could easily slip and drown. Oh it has a safety latch inside? So I can also destroy my floor in the process? I'll take three!
I want to feel like I'm being laid to rest in the funeral dream sequence in "Heathers" every time I take a bath.
