I currently have 4x4 off-white matte finish wall tiles in my full bath. It's on the 3 walls above the tub and on all the other walls in the bathroom as wainscoting. I really like the tile because of it's flexibility for decorating. Unfortunately, the grout on 2 of the walls above the tub and the wall board behind it is in bad shape and needs to be replaced. I would just replace it with the same tile, but I can't find a match anywhere (it's probably 20 years old). Is there a way to design the new tile around the tub, so that I can keep the current wainscoting and have the room look cohesive and not like a hodge podge?
