We are struggling to come up with a suitable work surface for our bathroom. It's in a little cottage and we have a simple white suite and the tiles are as the photo and we have white painted floor boards. What can we use for our counter top? We had thought white marble but it stains so easily. The counter top is about a foot above the wash hand basin so won't get splashed but will need to be moisture proof. It's about a foot deep and four feet long.
