If you have a tight bathroom it's still possible to create a larger shower space. This project used a wet room system. Learn how to design a larger shower in this article http://blog.innovatebuildingsolutions.com/2015/05/09/large-shower-making-bathroom-bigger/
Tile Ideas This bathroom is mostly unadorned, apart from one striking design element—the tile. The black linear tile ascends from the floor up the back wall of the shower, creating a streamlined, modern look.
Wetrooms—a luxurious and clever idea for a small bathroom. I lock the whole bathroom while taking a shower, so why not use the whole bathroom? Why spend so much time and money trying to make shower enclosures look good? (They're hideous.) Do away with them and have clean, beautifully-tiled, waterproof zen space in your bath for the same budget as sprucing up a shower and bathroom.
