Made from wine bottle cork stoppers collected from factories in Spain and Portugal, Cork Mosaic tiles are mounted the same as standard glass or ceramic tiles, and their waterproof quality makes them ideal for bathrooms and kitchens, says the firm. The cork chips come in two sizes: 1-inch diameter on a 12-inch-by-24-inch sheet, and 1?3/8-inch diameter on a 24-inch-by-24-inch sheet. The cork is 1/4 inch thick. 212.426.5500. www.habitusnyc.com.
