Black Quartz Undermount Sink for a Bold, Seamless Kitchen Install

This Karran single-bowl undermount sink brings a deep black quartz-composite basin to kitchen installations where a clean countertop edge and a strong visual statement both matter. It mounts beneath quartz, granite, or solid surface countertops and is certified cUPC and IAPMO.

Key Features

• Black quartz-composite construction with a consistent color throughout the basin body.
• Single bowl configuration with a 9-inch inside depth for large pots and sheet pans.
• Undermount installation into quartz, granite, or solid surface countertops only.
• Requires a minimum 36-inch cabinet to support the 31-3/4 by 19-3/4 inch footprint.
• Non-porous surface that resists staining and keeps food residue from bonding to the bowl.
• cUPC and IAPMO certified for compliance with North American plumbing standards.

One Deep Bowl That Handles Full Kitchen Load

A single uninterrupted basin this size handles the tasks that split-bowl sinks struggle with: full-size sheet pans, large stockpots, and oversized cutting boards all clear the walls without tilting. The 9-inch interior depth keeps water contained even during vigorous rinsing. For kitchens where most work flows through one sink, the open floor plan of a single bowl removes the divider that otherwise gets in the way.

Matte Black Quartz That Holds Its Look

The basin is made from quartz composite, a dense, engineered material where the black color runs through the body rather than sitting as a surface coating. The non-porous surface resists staining and does not allow food residue to bond to it, so the matte black finish stays consistent with routine cleaning. Unlike a painted or coated surface, the color does not depend on a protective layer that can wear through at the drain or the corners.

The Right Install for This Sink

This sink is designed for new countertop builds and full remodels where the counter is being fabricated. It is an undermount model, which means the bowl mounts beneath the counter surface into quartz, granite, or solid surface only. It is not designed to drop into an existing laminate cutout or to be top-mounted. The black finish reads especially well against light-colored stone countertops, where the contrast between the quartz surface and the dark basin creates a defined visual border. Confirm the cabinet is at least 36 inches wide and check the full bowl dimensions against the countertop cutout before ordering.
