I also put up these "faux" tiles in the bath room of my 2013 Columbus last year. My only concern was the very step price of $40 for a pack of 6 tiles. I will say that it really makes it look elegant and they have held up well in a damp environment. I thought about re-doing the backsplash behind the sink from countertop to the underside of the cabinets but it would have required a minimum of 4 packs of tiles and I would also have to do the area behind the stove, an additional 3 packs so it would match, so I decided to leave that area the way it came from the factory.
