Our collection of US made stainless steel kitchen sinks is made from 300-series stainless steel. The surface has a brushed satin finish to help mask small scratches that occur over time and keep your sink looking beautiful for years. The overall dimensions of the P0301US are 30 1/2" x 18 1/8" x 9" and a 33" minimum cabinet size is required. This sink contains a 3 1/2" Centered drain, is fully insulated and comes with sound-dampening pads. As always, our stainless steel sinks are covered under a limited lifetime warranty for as long as you own the sink.
