This functional and attractive, undermount, stainless steel sink is comprised of two unequal-sized basins. Both have the same length front to back and the same depth, but vary in width. The wide basin is on the right and the narrow one is on the left. The three-quarter inch radius corners of the TR31R provide maximum interior space. This model is 304-grade, cold rolled steel, at the industry standard 18-gauge thickness. The surface is given a brushed-satin finish which adds to its luster and masks minor scratches which could occur over time. Dense, sound-dampening pads and an insulation coating are applied to the underside. With an overall measurement of 31 1/8" x 18" x 9 5/8", it will require a minimum-width cabinet of 33". It is cUPC certified.
