Description Saltillo Mexican Tile, from the Saltillo region of Coahuila, Mexico is a time-honored classic look of the South West. Proline has combined the look into an 18″ x 18″ square tile pattern. The tiles are surrounded by a sand grout line for a more realistic quality. Looking for an accent piece, check out our Spanish Flair Border Art tool. This tool is also available in a 6″ X 6″  & 12″ x 12″ tile.
