The use of a photographic mural makes a small space like this look huge. These images come on a roll and are hung like wallpaper, so they make a straightforward DIY task. Just ensure you centre the image and work outwards if the positioning is important, as in this example. 

You can make a bathroom look as if it’s in a forest, on a beach, at the end of a pier or in any of numerous other beautiful places. Lots of wallpaper companies offer this option now, so shop around."
