Details
Bring understated beauty and effortless versatility to your kitchen with the Kohler Riverby undermount single-bowl workstation kitchen sink. A single, large bowl gives you generous room to soak pots, wash produce, and clean oversized cookware, while a bottom that gently slopes toward the offset drain keeps water from pooling and frees up workspace and storage beneath. Crafted from enameled cast iron, this undermount kitchen sink resists chipping, cracking, and burning, so it stays beautiful and dependable through years of daily use. A complete set of accessories transforms it into a true workstation, including a wood cutting board, a dishwasher-safe drain board, a colander and drying rack, a soaking bin, and a stainless steel sink rack that protects the surface. Five oversized faucet holes make it easy to add the faucet and accessories you want, so you can tailor the space to fit how you cook, clean, and gather.
