I stopped by the Arizona Tile store today and they have a beautiful Calacatta polished porcelain tile for TIA :)
We bought travertine from Arizona for a backsplash in the kitchen about 2-1/2 years ago. Although we installed it ourselves, they were very helpful in determining exactly what products we needed and were generous with the advice. We even mixed some glass accent tiles in with the travertine, and they were helpful with advice on that. We've been pleased with the tile and would go back.
