Riverby 33" x 22" x 9-5/8" Under-Mount Single-Bowl Kitchen Sink with Accessories

The understated beauty of this Riverby sink makes it an elegant and versatile addition to the kitchen. A single, large bowl provides ample space to soak and wash cookware, while a sloped base to a single offset drain minimizes water pooling. Crafted from enameled cast iron, this sink resists chipping, cracking, or burning for years of beauty and reliable performance. It comes with a custom-fit colander with integral cutting board, a utility rack with soaking cup, and a left-hand, stainless-steel bottom sink rack.
