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

The BLANCO DIAMOND 1-3/4 Low Divide Reverse Sink is a premium double-bowl undermount kitchen sink engineered for flexibility and efficiency. Its low internal divide and reverse bowl orientation (larger bowl on the right) allow easy handling of large cookware and bakeware while maintaining two functional bowls. Constructed from BLANCO’s SILGRANIT® quartz composite, the sink offers exceptional durability, resisting heat, scratches, stains, chips, and impact. The non-porous, hygienic surface ensures easy cleaning and long-lasting performance, and the rear-positioned drains maximize usable interior space and under-sink storage. Backed by BLANCO’s limited lifetime warranty, this sink is ideal for modern kitchens with demanding workflow needs.

Key Features

• SILGRANIT® Quartz Composite Construction – Premium granite composite (~80% natural quartz) engineered to withstand heat, scratches, stains, chips, and impact.

• Low Divide Double Bowl Design – Two unequal bowls separated by a low-profile divider for easier handling of large pots and pans.

• Reverse Orientation – Larger bowl on the right side for preferred workflow.

• Rear Drain Location – Maximizes usable interior space and efficient under-sink storage.

• Undermount Installation – Sleek, seamless integration with countertops.

• Hygienic, Non-Porous Surface – Smooth surface repels liquids, grime, and food particles for fast, easy cleaning.

• Limited Lifetime Warranty – Backed by BLANCO for manufacturing defects under normal use.

Available Colors / Finishes

• Coal Black – A rich, deep dark pitch-black finish with a bold, dramatic presence. Coal Black delivers a sleek, modern look that anchors the kitchen with confidence and pairs beautifully with contemporary cabinetry and metallic accents.

• Anthracite – A deep charcoal-black tone with subtle granite flecking that adds depth and texture. Anthracite offers the sophistication of black with a softer, more dimensional stone appearance.

• Cinder – A dark slate gray inspired by natural stone. Cinder strikes the perfect balance between black and gray, offering a refined, grounded neutral that complements both modern and transitional spaces.

• White – A crisp, clean white with a timeless appeal. Bright and versatile, this classic finish enhances light and contrast, making it an effortless choice for both kitchens and laundry rooms.

• Truffle – A soft, earthy taupe blending warm brown and gentle gray tones. Truffle brings subtle warmth and organic elegance, creating a refined neutral that pairs beautifully with natural materials and layered finishes.

• Café Brown – A warm, medium brown reminiscent of milk chocolate. Café Brown adds richness and comfort to the space, offering a welcoming, grounded look with understated sophistication.

• Soft White – A creamy, warm white designed to complement quartz and stone surfaces. Soft White delivers a gentle, inviting tone that feels refined and cohesive rather than stark. Blanco’s newest color has been an immediate success, answering the industry’s demand for a perfectly balanced, in-between tone.

• Volcano Gray – A rich mid-tone medium gray with warm undertones and a smooth, stone-inspired finish. Deeper than light gray but lighter than charcoal, Volcano Gray offers a substantial, modern look and pairs exceptionally well with stainless steel and dark metal appliances.

Featured Throughout the Entire Color Collection: All Blanco Silgranit sinks are finished with a sophisticated eggshell sheen, offering a matte appearance enhanced by a gentle, light-reflecting glow
