Where is the bathroom? / Var ligger badrummet?
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?.
