Details
Bring understated beauty and effortless function to the heart of your home with the Kohler Riverby 33" undermount single-bowl workstation kitchen sink. A single, generous bowl gives you ample room to soak and wash even your largest cookware, while the bottom gently slopes toward an offset drain to prevent water from pooling and increases workspace above and storage below. Crafted from enameled cast iron, this undermount kitchen sink resists chipping, cracking, and burning, so it holds its beauty and performs reliably for years. Everything you need to prep and clean is included, a custom-fit colander with an integral cutting board, a utility rack with soaking cup, and a left-hand stainless steel sink rack. Five oversized faucet holes make it easy to add the faucet and accessories you prefer, and the 9" depth offers a workspace built for real cooking. Ideal for anyone who would like a durable, versatile kitchen sink that turns everyday tasks into something a little more streamlined.
