Karran Quartz Undermount Sink for a Black-Finish Kitchen Build

This Karran double-bowl undermount sink brings a matte black quartz finish to a 50/50 equal-bowl kitchen layout, mounting beneath granite, quartz, or solid surface countertops for a seamless, rimless install.

Key Features

• Black quartz composite construction pairs a dense, hard-wearing body with a consistent matte black finish throughout.
• Equal 50/50 double-bowl configuration divides the basin into two identically sized bowls for separating tasks.
• Undermount installation into granite, quartz, or solid surface countertops keeps the counter edge clean and uninterrupted.
• Minimum 36-inch cabinet required to accommodate the 32-inch overall width.
• 9-inch inside depth in each bowl provides enough clearance for large pots and baking sheets.
• cUPC and IAPMO certified for compliance with North American plumbing standards.

Built for a Dark-Finish Kitchen

Black hardware and black fixtures have become a standard choice in contemporary kitchens, and a black sink anchors the palette without relying on a secondary finish to carry the look. This sink fits that role precisely: the quartz composite delivers a deep, uniform black that holds its tone alongside black pulls, matte black faucets, or dark countertop veining. Because the color runs through the quartz body rather than sitting on a surface coating, chips and scratches do not expose a different color underneath. For designers specifying a black kitchen package or contractors installing one, the finish reads as intentional rather than incidental.

Quartz Composite Material and Sink Dimensions

The sink is made from quartz composite, an engineered material that combines crushed quartz with resin binders to form a dense, non-metallic basin. The result is a surface that is harder than most acrylic alternatives and heavier than stainless steel, with a matte texture that keeps water spots less visible than a polished surface would. Each of the two equal bowls measures 14-1/2 inches in length, 15-3/4 inches in width, and 9 inches in depth, giving a usable basin that handles full-size cookware comfortably. The 3-1/2-inch drain opening in each bowl accepts standard basket strainers.

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. Because it is an undermount, it must be installed beneath the countertop surface rather than dropped in from above, and it is suited specifically for granite, quartz, and solid surface counters that can support an undermount bond. The 36-inch minimum cabinet width is a hard fitment requirement, so confirm cabinet size before ordering. It suits homeowners building a statement kitchen around a dark palette, designers specifying a coordinated black fixture package, and cabinet shops supplying sink hardware for a complete kitchen build.
