Constructed from premium stainless steel, KOHLER® Undertone brings home the durability, quiet performance, and polished look of professional kitchens. This undermount kitchen sink features an engineered sound-absorption system that significantly reduces disposal and dishwashing noise. The sink's high/low design features a smaller disposal bowl for easier food prep and cleaning, and a larger, deeper main bowl with plenty of room for bulky items. A mirror-finish edge adds an elegant accent.
