Travertine bathroom floor tiles are a popular building material used in bathroom areas. Travertine is an excellent material for bathroom floors. Since the surface of travertine is so often filled with holes, this natural texture helps travertine floors to be slip resistant when they are wet. Travertine bathroom floor tiles are available in multiple colors and finishes. Consider using travertine in a tumbled finish for a warm, soft and rustic look throughout the bathroom. Shower floors of the same material sized to 2-inches or smaller are the perfect complement.
