The large/medium bowls allow you to keep clean and dirty dishes separate, while a sloped base 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 stainless-steel bottom sink rack.
