A 32-Inch Black Quartz Undermount Sink for a Bold Kitchen Finish

This Karran quartz undermount sink brings a deep matte black finish to a split double-bowl layout, mounting beneath granite, quartz, or solid surface countertops for a clean, rimless look at the counter surface.

Key Features

• 60/40 double-bowl configuration with a larger left bowl (15-1/4 x 18-1/2 inches, 9 inches deep) and a smaller right bowl (12-3/4 x 16 inches, 9 inches deep) for dedicated task separation.
• Quartz composite construction with a matte black surface that holds color throughout the material body.
• Undermount installation designed for granite, quartz, and solid surface countertops.
• Requires a minimum 36-inch base cabinet to accommodate the 32 x 21-inch footprint.
• cUPC and IAPMO certified for code compliance in residential and commercial kitchen installations.
• 3-1/2 inch drain openings on both bowls for standard waste fittings.

Separate Bowls, One Streamlined Counter

A 60/40 split puts the larger bowl on the left for soaking a sheet pan or rinsing a full load of produce, while the right bowl stays free for quick rinses, a cutting-board rinse, or draining a colander. The asymmetric division gives you more working room in the dominant bowl without losing the convenience of a second basin for overflow tasks. Because the sink mounts from beneath the countertop, the counter surface runs unbroken to the bowl edges with no raised rim to interrupt wiping down.

Black Quartz That Earns Its Place in the Design

The sink is made from quartz composite, an engineered material that carries its color all the way through rather than relying on a surface coat. Matte black quartz reads as intentional in kitchens built around dark cabinetry, black hardware, or high-contrast palettes, and it holds up to the daily traffic a primary kitchen sink handles. The composite body resists the impact and temperature swings that a main sink takes on, and the matte finish keeps water spots from standing out the way they do on polished surfaces.

Where This Sink Works Best

This is the right sink for a kitchen remodel or new build where the countertop is being fabricated from scratch in granite, quartz, or solid surface. It suits designers specifying a black finish to anchor a high-contrast kitchen, cabinet shops building out a 36-inch or wider sink base, and homeowners planning a kitchen around a bold, unified look rather than a neutral one. The cUPC and IAPMO certifications keep it on the list for permitted residential and light-commercial work. Because it is an undermount, it needs a countertop that can support that installation method, so it is planned in from the start rather than swapped into an existing cutout.
