I'm thinking I paid about $900 for the 3x12 marble subway tile for my backsplash on 4 walls. I got a good deal - was told that it's usually about $1500.

Here is a link for calculating tiling cost based on zip code:

I live in a HCOL area. For the contractor to remove my old kitchen backsplash, repair the drywall and install the new backsplash, I believe it was $1,200 (for about 40 sq ft). There were a lot of cuts that needed to be made because I have a bump out behind my sink with 2 casement windows and he tiled in that area as well. My subway tiles are 3x9. The cost was just for the labor.
