The understated beauty of this KOHLER 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 top-mount kitchen sink resists chipping, cracking, or burning for years of beauty and reliable performance. It comes with a custom-fit colander with integral cutting board and a left-hand, stainless-steel bottom sink rack.
