The Blanco diamond 60/40 double bowl dual mount kitchen sink features a 60/40 bowl design, offering plenty of room for rinsing, washing, soaking, spraying, and straining operations. The 60/40 bowl split allows for washing larger items while leaving the smaller bowl open. The diamond 60/40 can be installed as a drop-in or under-mount sink. This kitchen sink is made of silgranit, a patented, certified granite composite material that is engineered to take on the toughest kitchen tasks. Silgranit is heat, scratch, stain, chip, and impact-resistant, making it stronger and more durable than other sink materials. It will not blister, burn, melt, or discolor from hot pots, pans, or baking sheets straight from the oven. Beautiful and highly functional with its non-porous, hygienic surface, it pushes away liquids and residue resulting in low maintenance, easy-to-clean, long-lasting material. The diamond double-bowl kitchen sink easily conquers the demands of everyday life.
