Terracotta Light Ivory Concrete Effect Matt Anti Slip Porcelain Tiles are made from unglazed porcelain with a 9mm thickness and a matt finish. The light ivory colour provides soft, calm appearance, while the concrete effect adds a simple modern style suited to everyday home spaces. With an R11 slip rating. The rectified edges help each tile sit cleanly against the next, and the 20 different faces provides gentle variation so the finished surface looks more natural and less repetitive. These tiles can be used on both interior walls and floors.
