A Black Quartz Undermount Sink for a Bold, Low-Maintenance Kitchen

The Karran QU-820-BL-PK1 is a single-bowl quartz undermount kitchen sink finished in Black, designed to mount beneath granite, quartz, or solid surface countertops in cabinets 27 inches wide or greater.

Key Features

• Black quartz composite body with a deep matte finish that anchors a modern or contrasting kitchen palette.
• Single-bowl configuration with a 22-inch interior length and 9-inch depth for generous workspace.
• Undermount installation into granite, quartz, or solid surface countertops for a seamless counter edge.
• cUPC certified and designed for a minimum 27-inch cabinet width.
• 3-1/2-inch drain opening sized for standard waste fittings.

One Deep Bowl for Everyday Kitchen Work

A single wide bowl handles the jobs that split configurations struggle with: large sheet pans, stock pots, oversized cutting boards that need a rinse. The 9-inch interior depth keeps water in the basin during busy prep sessions and gives enough room to submerge tall items without awkward angles. Because the rim sits below the counter, wiping crumbs and liquid straight from the counter surface into the sink takes one motion instead of lifting over a ledge.

Quartz Composite in Matte Black

The sink is made from quartz composite, an engineered material that combines the density and look of natural stone with a consistent color and surface throughout the body. The Black finish runs through the material rather than sitting as a surface coating, so chips and scratches that reach the body do not expose a different color underneath. The matte surface minimizes the appearance of water spots and light marks between cleanings, which is a practical advantage in a high-contrast finish.

Where This Sink Fits

This is the right sink for a kitchen renovation or new build where the countertop is granite, engineered quartz, or solid surface and the design calls for a strong, dark anchor in the workspace. Black pairs especially well with white or light-toned countertops for maximum contrast, and reads equally well in an all-dark scheme with black or charcoal counters. Because it is undermount-only, it needs to be planned into the countertop fabrication rather than retrofitted into an existing cutout. A designer specifying a contemporary or transitional kitchen, a homeowner doing a full remodel, or a cabinet shop building out a kitchen package will find this sink a direct fit for that workflow.
