I've got that wallpaper in there that you can just paint a new colour on and the bottom half is wood panelling so you can paint that too. It's not a massive bathroom so I tend to give it a new coat of paint once every 3-4 months and change the colour scheme in there with different accessories etc.
That's downstairs. The bathroom upstairs is bigger but it's tiled so I don't have to keep redecorating it.
