Crossville's WeatherStone for indoor and outdoor use
XT is slip-resistant and able to brave the weather outdoors. UPS is smoother and easy to clean for indoor use, Crossville says. The tiles are offered in five rustic hues, and in multiple sizes and trims. Sizes include 3-by-3-, 3-by-6-, 6-by-6-, 6-by-12-, 12-by-12-, 12-by-18- and 18-by-18-inch formats.
