With its curved corners, the TR26 is a square, single basin, designed to provide a softer look. As with all 3/4" radius sinks, the walls are straight and the corners tight; but slightly rounded for cleaning convenience and high style. Made from one piece of 304-grade stainless steel, its brushed satin finish hides minor scratches that could occur over time. It's available in three thicknesses: standard 18, heavy-duty 16, and a hefty 14 gauge. The overall dimensions of the TR26 are 26" x 18" x 9" and a 27" minimum cabinet size is required. Covered by our limited lifetime warranty, your satisfaction is guaranteed. All our stainless steel sinks are completely insulated and come with sound dampening pads to prevent condensation and reduce noise.
