With soft curves, the KOHLER Cairn sink offers transitional style to suit contemporary and traditional kitchens alike. The Cairn undermount kitchen 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 Cairn Smart Divide kitchen sink features a low barrier that divides the two bowls, making it easy to wash and rinse large items while still keeping the two bowls separate.
