The BLANCO DIAMOND 40/60 REVERSE DOUBLE BOWL UNDERMOUNT KITCHEN SINK with LOW DIVIDE features a 40/60 bowl design, offering plenty of room for rinsing, washing, soaking, spraying and straining operations. The 40/60 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.
