This is probably a stupid question... I have a granite countertops and the same granite flows up the wall. I would like to install different backsplash, but don't want to do it if I'm going to have to remove the existing granite on the wall. That sounds expensive and not easy to do. to Is that even possible? Would it looks funny to put tile backsplash on top of granite backsplash? Thank you in advance for any insight!
