We had tile in the first XL II along with carpet and I think I have a box of the tile in the hanger if you want to look over the style and texture. The current coach has granite entry and WC tile, but hand scraped wood in the rest of the coach. Also, the XL we had was mostly carpet with tile in the galley. Of the three, the wood wins hands down. Easier to clean, less maintenance and it looks "warmer"
We changed the tile ourselves in the first coach. Not a hard job, but the guy who laid the new carpet was sweating like a fat chick when that chore was over. Lots of cutting for such a small space. On the tile, we got several samples from a place over on Louetta, put them in place to see how it matched up and went to work.
Now the wallpaper - never again. My marriage has survived two wallpaper jobs and there won't be a third.
