A timeless bathroom backsplash idea that never goes out of style? Tile and stone in pretty much any one of the many different shades of gray. Far from boring, gray is neutral but elegant, and can range from pale and pearlescent to dark and dramatic, and a bath splash can range from teeny tiny tile to large-scale stone slabs.

2. Dark Soapstone Bathroom Backsplash
For a gray bathroom backsplash idea that's on the dark side, opt for soapstone, slate, or even concrete. (Soapstone is a particularly practical choice: In addition to looking sharp, it's extra durable and easy to clean.) Add in a little ledge above for added detailing while you're at it, as seen in this bathroom by Shea from Studio McGee.
