I have 2 completely different designs in mind! One is tiles, one is wallpaper.
Tiles would go on 2 walls - behind sink and loo and behind shower (big walk in shower, no bath). Painted white walls elsewhere. White floor.
Wallpaper would go behind sink and loo and then would have to think of something else for shower area. Would it be possible to wallpaper it and then stick one of those clear Perspex panels over it? Or would it just peel straight off?
