Badrummet is the place where you take a shower or a bath, which may or may not also have a toilet seat in it. So in a restaurant etc, they will be very surprised if you ask for the location of the badrum. Even in a private home, we are not so prude as to ask for the badrum, we just ask Var ligger toaletten? or (more colloquially) Var är toan?.
Awesome, had no idea, it's important to know how people really speak in their language. Tack så mycket!
