The 3218C is part of our new line of economically-priced sinks. It is constructed from 18 gauge, 304 grade stainless steel with a chromium/nickel content. The surface has a brushed satin finish to help mask small scratches that occur over time and will keep this sink looking beautiful for years. The overall dimensions of the 3218C are 32 1/4” x 18” x 9” and a 33” minimum cabinet size is required. The 3218C has the same outer dimensions and cutout size as the 3218A and 3218B and a cutout template is included with purchase. Also included with this sink is a 3 1/2” offset 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.
