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 M19 are 19 1/4" x 16 1/4" x 7" and a 21" minimum cabinet size is required. This sink requires a pop-up drain. As always, our stainless steel sinks are covered under a limited lifetime warranty for as long as you own the sink.
