I suppose that depends on levels of clumsiness, damp and whether anyone's habitually weeing on the floor. (As you can imagine, we have quite a lot of the former, and not very much of the latter.) The carpeted bathroom we had in the Sheffield house wasn't too bad.
OTOH, never share a carpeted kitchen with students.
Now I think about it, don't share a bathroom with them either, regardless of floor covering. Actually, just don't live with students.
