A Matte Black Single-Bowl Sink Built for Dark and Contrast Kitchens

This Karran single-bowl quartz undermount sink finishes in a deep, consistent black, making it a natural fit for kitchen designs that lean on dark countertops, two-tone cabinetry, or high-contrast hardware schemes. It mounts beneath quartz, granite, and solid surface countertops and requires a minimum 27-inch base cabinet.

Key Features

• Single bowl undermount design with an uninterrupted basin for washing large pots and pans.
• Black quartz composite construction with color carried throughout the body, not just on the surface.
• 9-inch inside bowl depth for generous clearance on tall cookware and sheet pans.
• Designed for quartz, granite, and solid surface countertops only, not laminate or tile.
• cUPC and IAPMO certified for plumbing code compliance in the U.S. and Canada.
• 3-1/2 inch drain opening for standard kitchen strainer compatibility.

What the Black Finish Does for the Kitchen

Undermount sinks disappear behind the countertop rim, but the color still reads through the bowl. A black sink in a lighter kitchen creates a deliberate visual anchor, while the same sink in an all-dark kitchen reads as seamless. The quartz composite carries the black color all the way through, so chips and nicks at the rim edge do not expose a different-colored core. That consistency is what separates a through-body quartz color from a coated or painted surface finish.

Material and Construction

The sink body is quartz composite, an engineered material made from natural quartz bound with acrylic resin. The quartz content gives the basin its density and surface hardness, while the resin matrix produces the matte texture and a non-porous finish that resists staining and keeps food residue from adhering. The 9-inch bowl depth handles standard kitchen loads without feeling cramped. All dimensions run edge to edge at 21-3/8 inches by 17-7/8 inches, with the same measurement carried both overall and inside the bowl, meaning virtually the full footprint is usable basin.

Where It Works Best

This sink belongs in new kitchen builds and countertop replacement projects where the countertop is being fabricated new. It is not a drop-in replacement for an existing cutout. A 27-inch base cabinet is the minimum, which suits most standard single-sink cabinet runs. It works well in modern farmhouse kitchens with black hardware and white or wood cabinetry, in contemporary dark-on-dark schemes with charcoal quartz countertops, or in a designer kitchen where the plumber, cabinet maker, and countertop fabricator are coordinating the install together. Because it is not ADA compliant, it is not the right choice for accessible kitchen projects.
