English says bathroom even if they're not showers on them

That would be a toilet.

I know English does, but e.g. German doesn't, that's why I'm interested. A "Badezimmer" (literally "bathroom" or "bathing room") is very much a room in private homes (or hotel rooms) where you take a shower or a bath. That's usually also where the ~~loo~~ toilet is, for convenience reasons. A communal / public room with the single purpose of using the toilet (like in a shop) is "the toilet(s)", one with the purpose of taking a shower (like at a gym) is "the shower(s)". (This probably says something about Germans in general)

And now I'm waiting for some compatriot to rip me a new one because in their dialect it's perfectly normal to look for the "Badezimmer" at Kaufhof and wtf am I talking about.
