Full bath

My room here at Durham is a collegiate dorm room. Literally. But it includes a private bathroom, which is quite small, and consists of a toilet, a sink, and a shower. The shower isn't separated from the rest of the room by anything. There is a curtain, but the floor is on the same level and there's no drain near it. When you need to shower, you pull the curtain around as best as you are able, and then go for it. The entire bathroom floods. Apparently the floor is declined towards the toilet, and there must be a drain under that somewhere, but it's still very strange. And then the floor of the entire bathroom is wet for hours. Someone please explain to me why the Europeans can't figure out how to make normal showers!!
