Details
Bring understated beauty and everyday versatility to the heart of your home with the Kohler Riverby undermount workstation kitchen sink. Offset double-bowls provide ample room to soak and wash cookware, while a sloped bottom directs water toward offset drains to minimize pooling and keep your workspace clean. Crafted from enameled cast iron, this undermount kitchen sink resists chipping, cracking, and burning, so it holds its beauty and reliable performance for years. The offset drains also increase storage space in the cabinet below, making the most of every inch. A thoughtful set of accessories, including a wood cutting board, a dishwasher-safe drain board, a colander and drying rack, a soaking wash bin, and a stainless steel sink rack, turns this workstation sink into a true prep hub for busy home cooks. With generous depth for real workspace and a design that answers the needs of daily life, the Riverby workstation sink makes cooking, cleaning, and gathering feel effortless.
