Karran Quartz Undermount Sink for a Black-Finish Kitchen

This Karran quartz kitchen sink is a 60/40 double-bowl undermount sink in Black, engineered for installation beneath granite, quartz, or solid surface countertops and certified to cUPC and IAPMO standards.

Key Features

• 60/40 double-bowl layout with a larger left basin for washing and a smaller right basin for prep or rinsing.
• Black quartz composite construction built from natural quartz and acrylic resin for a dense, matte surface.
• Undermount installation into granite, quartz, or solid surface countertops.
• Requires a minimum 36-inch cabinet to accommodate the 33-1/2 inch overall width.
• cUPC and IAPMO certified for plumbing code compliance.
• 3-1/2 inch drain openings in each bowl for standard basket strainer or disposal fitment.

Two Bowls Sized for Real Kitchen Workflows

The 60/40 split puts a deeper, wider basin on the left for soaking pots, rinsing large cutting boards, or handling the bulk of dishwashing, while the right basin stays available for prep tasks, draining vegetables, or holding a colander without giving up the main bowl. That separation is what makes a split-bowl sink more useful than a single basin during busy cooking sessions or cleanup. Because the sink is an undermount, the countertop surface runs directly to the bowl edge with no rim break, making it straightforward to sweep debris straight into the sink.

Black Quartz Composite That Holds Its Look

The Black finish here is part of the material itself, not a coating applied over a base. The sink body is quartz composite, a dense blend of natural quartz and acrylic resin, which gives the Black color a consistent depth and a matte texture that does not show fingerprints or water spots the way a polished surface would. The Black finish also reads as a deliberate design choice rather than a default, so it works well in kitchens where dark hardware, matte fixtures, or two-tone cabinetry are part of the scheme.

Where This Sink Fits Best

This sink is the right call for a kitchen remodel or new build that includes a solid hard-surface countertop, specifically granite, quartz, or solid surface, and a 36-inch or wider sink base cabinet. It is an undermount-only sink and is designed to be fabricated into a new countertop rather than dropped into an existing cutout. Kitchens going for a dark or matte aesthetic, including designs with black hardware pulls, matte fixtures, or charcoal cabinetry, get the most out of the Black finish. Designers specifying for a cohesive monochromatic palette will find the Black quartz a strong anchor piece for the kitchen.
