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 left and the narrow one is on the right. The three-quarter inch radius corners of the 3160L provide maximum interior space. This model is made of 304-grade, cold rolled steel and is available in three thicknesses: standard 18, heavy-duty 16, and a hefty 14 gauge. This sink contains 3 1/2" drains, is fully insulated and comes with sound dampening pads. 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.
