Since I liked the tiles for the bathroom basement so much, I decided to do the same in my bedroom. Only $10 for a box of 20 tiles at Family Dollar. This bathroom is much smaller, but due to the confined space and more complex fitting of tiles I think it took me about as long to do.
The gray works well too because I already had a gray rug and towels. I did buy a new shower curtain to replace a white one.
