Karran Quartz Undermount Sink for a Bold, Dark Kitchen

This Karran single-bowl kitchen sink is a black quartz undermount designed to drop beneath granite, quartz, or solid surface countertops and hold its own as a strong design element in the kitchen.

Key Features

• Black quartz composite construction with a color that runs through the material, not just a surface coating.
• Undermount installation into granite, quartz, or solid surface countertops, producing a clean, rimless counter edge.
• Single bowl interior measuring 30 inches long by 16-1/4 inches wide by 9 inches deep for generous working room.
• Requires a minimum 36-inch base cabinet to accommodate the 32-inch overall sink length.
• 3-1/2 inch drain opening sized for standard strainer fittings.
• cUPC and IAPMO certified for plumbing code compliance in the United States and Canada.

Where Black Makes the Difference

Black sinks work in two very different kitchen directions: a dark, dramatic palette where the sink disappears into matte countertops and cabinetry, and a high-contrast setup where black reads sharply against white or light stone. Either way, the single-bowl layout keeps the basin uninterrupted, so there is nothing to split the visual weight. A 9-inch bowl depth handles tall pots and sheet pans without piling them above the rim, which is the practical side of a large single bowl that comes up in daily use.

Quartz Composite in a Deep Matte Black

The sink is made from quartz composite, an engineered blend where quartz particles are the dominant component, bound into a dense, uniform body. The black finish is integral to the material rather than applied to the surface, so chips and scratches do not expose a different color underneath. The quartz composite body is non-porous, which means it does not harbor residue the way a textured or porous surface might, and the matte black finish holds up against the routine of a working kitchen without requiring the care that a polished surface demands.

Who Plans This Sink In

This sink suits a kitchen remodel or new construction where the countertop is being fabricated from scratch. Because it is an undermount, it needs the counter fabricated around it, which means it is not a drop-in replacement for an existing opening. Designers specifying a dark kitchen or a two-tone contrast scheme will find the black finish useful where a stainless or white sink would break the color story. Cabinet shops building or installing 36-inch base runs have the minimum cabinet width this sink requires. The kit designation indicates this SKU ships as a package that includes the sink; confirm kit contents at checkout if accessories matter to the project schedule.
