A Black Quartz Undermount Sink Built for Dark and Contrasting Kitchen Designs

The Karran QU-820-BL is a single-bowl quartz undermount kitchen sink finished in Black, designed to mount beneath granite, quartz, or solid surface countertops in a 27-inch or wider base cabinet.

Key Features

• Black quartz composite construction that holds its color through the full depth of the material.
• Single-bowl configuration with a 22-inch interior length and 9-inch depth for full-size pots and sheet pans.
• Undermount installation into granite, quartz, or solid surface countertops.
• cUPC certified for residential plumbing compliance.
• 3-1/2 inch drain opening compatible with standard drain and disposal flanges.
• Minimum 27-inch base cabinet required for proper fit.

One Bowl, Full Depth, No Interruptions

A single bowl this size handles the work that trips up smaller or divided sinks: oversized stockpots, large sheet pans, and deep Dutch ovens all drop straight in without tilting. The 9-inch bowl depth keeps splashing contained and gives enough clearance for soaking tall items upright. Because it undermounts, the countertop surface runs unbroken to the bowl edge, making it easy to sweep water and debris directly into the sink without a rim in the way.

Black Quartz Composite That Works With the Design

The sink is built from quartz composite, an engineered material where color runs through the body rather than sitting as a surface coating. In Black, that means chips and scratches at the rim or bowl edge stay inconspicuous because the material underneath matches. The matte black surface also reads differently under kitchen lighting than polished finishes do, tending to recede visually against dark countertops or stand as a sharp contrast against white and light stone. It suits countertop pairings in white quartz, light marble-look surfaces, or can anchor an all-dark palette in black granite or soapstone.

Where This Sink Fits

This sink is a practical choice for kitchen remodels and new builds where the countertop is granite, quartz, or solid surface and the base cabinet is 27 inches or wider. Designers specifying a black accent in a two-tone kitchen, contractors installing a bold single-material kitchen, and homeowners building a kitchen around a dark-and-light contrast will all find the color practical rather than purely decorative. It is not ADA compliant, so for accessible design projects a different configuration is needed. The cUPC certification satisfies standard residential plumbing code requirements across most jurisdictions.
