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)
Just print off any picture you want, then spray paint a piece of wood black, cut the picture to match the size of the wood. Using Mod podge coat the wood then lay the picture on top. Once it dries, put a layer of mod podge over the top of the picture.
