Karran Quartz Undermount Sink for a Bold, Dark Kitchen

This Karran quartz kitchen sink is a 50/50 equal double-bowl undermount sink finished in Black, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• Black quartz composite construction delivers a deep, consistent color that reads as part of the countertop rather than a contrast insert.
• Equal 50/50 double bowl layout splits the sink evenly for separating wash and rinse or prep and cleanup tasks.
• Undermount installation into granite, quartz, or solid surface countertops keeps the counter edge running clean to the bowl rim.
• 9-inch inside depth in both bowls accommodates large pots and sheet pans without crowding the basin.
• Requires a 36-inch minimum cabinet width for proper fit and clearance.
• cUPC and IAPMO certified for plumbing compliance in residential and commercial installations.

Built for Kitchens Where the Sink Is Part of the Design

A black sink in a dark or high-contrast kitchen is a deliberate material choice, not a neutral one. This sink works with matte black hardware, dark stone countertops, and charcoal or navy cabinetry where a stainless or white basin would break the palette. It also reads cleanly against light countertops as a focal contrast element. The undermount installation keeps the counter surface uninterrupted, which matters in a design-forward kitchen where the seam between counter and sink is part of the finish.

The two bowls split evenly at 50/50, so neither side feels like an afterthought. Both measure 9 inches deep, which handles stock pots and rimmed baking sheets that would overflow a shallower bowl.

Quartz Composite Material and Black Finish

The sink body is quartz composite, a dense, engineered material that holds its color through the full depth of the basin rather than relying on a surface coating. The Black finish is consistent and matte, so it does not show water spots the way a polished surface would, and it holds up to the temperature swings that come with kitchen work. The drain opening in each bowl is 3-1/2 inches, sized for standard basket strainers.

Where This Sink Fits Best

This is the right sink for a kitchen renovation or new build where the countertop is being fabricated from granite, quartz, or solid surface, and where the designer or homeowner wants the sink material and the countertop material to feel unified rather than layered. Cabinet shops and contractors specifying for a dark or monochromatic kitchen will find the Black finish coordinates across the color families used in those palettes. The 36-inch minimum cabinet width is a hard fit requirement, so verify the base cabinet before the countertop template is cut.
