Kohler’s Cairn is crafted from a proprietary new material called Neoroc — a rock-hard composite material that is designed to withstand years of use in the kitchen. Impact-, stain-, fade- and heat-resistant, it won’t chip or scratch and can handle heat up to 750° F. The sink is available in three configurations: a single bowl, a double-equal sink, and a large/medium double-bowl sink. Each design comes with one sink rack for surface protection and dish-cleaning convenience. On all three models, the dimensions measure to the popular 33” sink for typical 36” cabinet installations.
