I'm in rented accommodation and on a limited budget. My bathroom is fairly small with black flooring and beige tiles, walk in shower. I'd like to brighten it up without spending too much. Any suggestions? The only things in there are a narrow wooden drawer unit, on the wall there's a blue abstract picture of the sea and a white framed mirror. Painted walls are white and the shower curtain is white. I've looked at coloured shower curtains but not sure what would go with the beige.
