Infinity Drain, a manufacturer of architectural and decorative drains, has introduced a clamping floor drain that has been redesigned to a more compact size. The new design allows for easier installation of a linear drain against the shower wall, eliminating the need of flooring material between the drain and the wall tile. Measuring just 3-1/4-in. in diameter at its narrowest part (compared to the traditional 6-1/2-in. diameter), this compact floor drain is available in three materials, including cast iron, PVC and ABS.
