Lay a timeless patterned patio with the Philadelphia Tumbled Roman Pattern Travertine Paver. Each set combines three sizes, 6x6, 6x12 and 12x12, that fit together in a repeating Roman pattern, and tumbled edges give these travertine pavers a worn, old-world feel. Quarried in Turkey and 1 1/4 inch (3 cm) thick, the stone shifts between beige, gray and brown, so the pattern gains depth across a large area. Besides outdoor paving, it is rated for residential and commercial floors, walls, shower walls and shower floors. Natural variation is part of travertine's character; we recommend sealing after installation. Edge a pool with the Philadelphia Tumbled 12x24 Extra Thick Bullnose Coping or the squarer 16x24 Extra Thick Eased Edge Coping. For a larger-scale pattern, compare the Philadelphia Tumbled 8 Inch Versailles Paver, and finish a wall nearby with the Philadelphia Splitface Ledger Panel. See the Philadelphia travertine collection.
