The S024 stainless steel undermount or topmount vanity sink is made from 304 grade stainless steel and is available in 18 gauge thickness. 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 S024 are 16 1/4″ x 16 1/4″ x 7″ and a 18″ 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.
