The BLANCO Diamond double bowl 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 still leaving the smaller bowl open. 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. Beautiful and highly functional with its non-porous, hygienic surface, it pushes away liquids and residue resulting in a low maintenance, easy to clean, long-lasting material. Combine the DIAMOND Double Bowl with a BLANCO faucet and accessories to create a BLANCO UNIT; a seamless, fully-integrated kitchen solution designed to transform kitchen chores into joyful experiences. Everything you need to drink, prep and clean, all in one place.
