+1 for Smart Tiles from Home Depot.
A few on here have done it, and I've read about it on a few different RV blogs. They are a little pricey IMO, but for what you get, I think it's worth it. The projects I've looked at have looked great, like that's the way they should come from the factory. I even watched a video where a guy installed them in a residential kitchen and it turned out really nice for the money and effort. I always thought the tile printed wall paper was kind of cheesy, and these tiles give it a much better look and much better functionality. They are smooth too, so cleanup is easy.
