We are thinking of putting one in an attic bathroom, and having a bathtub under. I would have gone for a normal velux, but think the pitch of the roof makes it a bit tight for a tall person (fine for me).
It is not the main bathroom, so it is not essential to make it easily usable by all (I think mainly I'll be using it) but wonder if that is being short-sighted.
Also, not sure how it would look in an old farmhouse. Pros, cons, cost?
