You can see on the picture above how much a wallpaper cut can be charming when used in a bathroom. If you opt for more natural textures, as in the photo above, neutral color wallpaper can be an attractive option.
This idea also shows how much the wallpaper can set a theme, as in this nautical style. And by placing the wallpaper on an upper part of the wall, you can set this theme without overloading the rest of the bathroom. The picture above shows how different sections of wallpaper placed opposite each other in the room can also help to reinforce the cohesion of the space.
