like tiles on shower floor and walls of shower.check out these bathroom tiles. I think it would be good in a small bath to use same floor & wall tile. This is a great example (though I won't be tiling shower)
I see a lot of "almost" bookshelves. They hold books and look "design-y" but they waste energy and space. If you are really into books, it's not about the cute shelves. It's about the books. Make that space hold as many as it can.
