A 12-inch linear drain with a tile-in option offers a sleek and functional design for modern showers. These drains are typically made of stainless steel for durability and corrosion resistance. The tile-in feature allows for a seamless look, as the tile from the shower floor can be inserted into the drain, making it almost invisible. This type of drain is engineered to provide efficient water flow and can be a stylish addition to any bathroom renovation or new construction.
