We're running bluestone from the exterior into the mudroom. The laundry room comes off of the mudroom, and it was also going to be bluestone, but there's an issue with angling the floor in there for the drain that will go in the center of the floor. So I need to pick a porcelain floor tile for the laundry room. It's a small room, and a solid color will work best. Any suggestions for what might work next to the bluestone, which will be full range thermal finish?
