This exterior tile is 3/4″ thick. It cannot be scratched or stained. Our popular 18″ x 36″ tile is sold in three different colors (from front to back in photo below) – Zermatt, St. Moritz and Davos. We also sell the standard 24″ x 24″ size in diffferent colors. If you are looking for a clean, symmetrical paving option with a contemporary style then our outdoor porcelain is a perfect fit.
