Kohler Cairn Smart Divide 33-1/2" Undermount Kitchen Sink & Reviews

With soft curves, the Cairn sink offers transitional style to suit contemporary and traditional kitchens alike. The Cairn 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.

Love the Koehler quality and the two sized sink. I can get a large roasting pan in the larger sink easily and use the second sink as my drain, keeping my counter space less cluttered.

This sink is exactly what i wanted. Best of both worlds - divided low but still able to wash all the big things, yet also still able to wash my produce, thaw things, etc. the surface is not completely smooth, a bit of a rough texture. I did notice some grey scuff if a pan hits it a bit harder or rubs, however i went into it knowing this would happen with any white sink. Overall, it’s beautiful. Did not come with the drains, but DID come with the bottom graits.

Finish:Black

Black surface shows ingrained soap scum. Saw hack to use vegetable oil for longer lasting shine.
