BLANCO DIAMOND 1-3/4 Low Divide Double Bowl SILGRANIT® Sink

The BLANCO DIAMOND 1-3/4 Low Divide Sink is a premium double-bowl undermount kitchen sink designed for function, durability, and easy maintenance. Part of BLANCO’s DIAMOND collection, it is crafted from SILGRANIT® quartz composite — a patented blend of approximately 80% natural quartz — offering outstanding resistance to heat, scratches, stains, chips, and impact. Its low divide design provides a smoother transition between basins, allowing flexible handling of large cookware and bakeware while reducing splashing. Rear-positioned drains maximize usable interior space and under-sink storage, and the non-porous surface repels liquids and debris for effortless cleaning. Backed by BLANCO’s limited lifetime warranty, this sink is ideal for busy kitchens and everyday use.
