Travertine is one of the most popular forms on tile that is chosen for modern architecture. It is commonly used as a floor tile in living rooms, kitchens, bathrooms and even exterior applications. The stone itself is characterized by pitted holes and troughs that are apparent throughout its surface. These troughs and holes occur naturally and give travertine its unique and natural look. Even though most travertine tile come with holes, most installers use grout to fill them. Travertine can be purchased in a variety of forms such as Filled, Un-Filled or Tumbled. Travertine tile is available in a multitude of sizes ranging from 1″x1″ Mosaic, 12″ x 12″ Tiles, to 24″x24″ Tiles. It is extremely important to seal travertine tile regardless of the application it is used for. Travertine Tile is a very porous stone with tiny holes as described above and needs to be sealed in order to maintain its appearance and prevent it from staining.
