The PL1213 Kitchen Ensemble features an undermount sink in an offset design, with a D-shaped bowl on the left and a smaller shallower rectangular bowl on the right. It is constructed of premium 304-grade stainless steel, 16-gauge and the surface has a brushed-satin finish to help mask small scratches that occur over time. Measuring 31½'' x 20¾'' x 9"(L) x 7"(R) it is fully insulated and comes with sound dampening pads. The ensemble includes five accessories: a beautiful wood cutting board, custom-cut to fit the larger sink perfectly; a pair of stainless steel grids, and a pair of durable strainers. The Polaris limited lifetime warranty applies. See the 3121R Kitchen Ensemble in which the basins are reversed.
