ATLA reader Genevieve Haines turned us onto these unique handcrafted Standing Pebble Tiles composed of tumbled marble, pebble, polished pebbles or graveled pebble from Los Angeles architectural retailer, Zation Stone. The natural interlocking 12"x12" tiles are advertised as suitable for both interior and exterior use, and flooring, walls, ceilings, walkways, fireplaces, patios, bathrooms floors, showers, gardens, decorative accents and are available in Bali Black Grey, Maluku Tan, Taipei Green, Sumatra Black, Ocalla Berry, Panu and White Timor. Stacking Flat Stone is available in four colors: Kutu White, Merak, Yucatan Brown and Palmero Cream. No prices listed, but they're listed as available thru retailers such as The Great Indoors and Emser Tile and Natural Stone. We're already imagining the soothing and massaging feel of these pebble tiles...ahhhhhhh [blissful smile]. Rock on!
