This is amazing. We discovered this on the blog Bookshelf.

This bath is made entirely out of books which Vanessa Mancini cut and fitted together over a metal frame to form a bath of books, which is suspended by four antique bath tub, lion-shaped feet. She intends to later cover it in layers of resin and has already applied proper taps and drain, so that it will be a utilizable, functional bath at all effects.
