The KOHLER Billings 29-1/2” undermount workstation kitchen sink raises the bar on functionality and professional styling with custom accessories that integrate seamlessly within the bowl’s ledge. With an eye toward food preparation as well as cleanup and storage, the included accessories are both thoughtful and practical. The Billings sink is made of KOHLER Neoroc, a matte-finish composite material designed for extreme durability and unmatched beauty. Richly colored to complement any countertop, Neoroc resists scratches, stains, and fading and is highly heat- and impact-resistant. The sink’s large, deep bowl allows you to soak and clean large cookware and bakeware and has easy-to-clean rounded corners.
