Hi. About 11 years ago I renovated a powder room. I installed a black granite floor and insisted on a black toilet. We converted an antique dresser into a sink. I loved it at the time. Now it looks dated to me. My question is: Can I keep the black granite floor and replace the toilet with a white one? The walls are a red toile wallpaper, which I would take down. Can a white toilet work on a solid black floor? Thanks!
