Pebbles are individually sorted to insure only using pebbles displaying the highest quality, size, color and flatness. These small, medium, and large premium pebbles are placed in an interlocking shape to create a pebble tile of unmatched consistency and quality. On a bathroom or shower floor, pebbles provide a subtle massage for the feet. Available in full sized sheets or as a border, the Mediterranean vignette displays show the versatility of this wonderful natural stone.
