Black Quartz Undermount Sink for a Modern Kitchen Install

This Karran double-bowl undermount sink brings a deep black quartz-composite surface beneath the countertop, pairing an uninterrupted counter edge with two asymmetric bowls sized for different tasks.

Key Features

• 60/40 double-bowl split gives you a larger prep bowl and a smaller rinse bowl side by side.
• Black quartz composite built from natural quartz and acrylic resin for a dense, consistent color throughout.
• Undermount installation into granite, quartz, or solid surface countertops, with a minimum 36-inch cabinet width required.
• Nine-inch depth in both bowls for handling large pots, sheet pans, and full-sized cookware.
• cUPC and IAPMO certified for confidence in code-compliance situations.
• 3-1/2 inch drain opening in each bowl, sized for standard basket strainers.

Two Bowls, Two Jobs

The 60/40 split puts a larger bowl on the left for washing and soaking and a smaller bowl on the right for rinsing, draining, or staging food prep. That asymmetry matters in a working kitchen: a full-size colander fits the large side while the smaller bowl stays clear. Both bowls run nine inches deep, so a stockpot or a hotel pan drops in without the handles hanging up on the rim. The black finish lets the sink anchor a two-tone kitchen palette without competing with lighter countertops or cabinet hardware.

Quartz Composite in a True Matte Black

The sink body is quartz composite, natural quartz blended with acrylic resin, so the black color runs through the material rather than sitting as a surface coating. The result is a consistent matte finish that does not show chips or worn edges the way a painted or enameled surface can. The dense composite holds its shape under the weight of a full load of dishes and handles the thermal swings of hot water draining directly into the bowl.

Where This Sink Fits Best

This sink is the right call for a new kitchen build or a full countertop replacement where the design calls for a bold, dark anchor piece. Because it is undermount only and designed for new countertop installations, it works best when the countertop is being fabricated at the same time. It installs into granite, quartz, or solid surface countertops and requires a cabinet that is at least 36 inches wide. Designers specifying a matte black palette and contractors building dark-toned kitchens will find the 32 by 21-1/4 inch footprint fits a standard 36-inch base run cleanly.
