A Black Quartz Undermount Sink for Kitchens Built Around Contrast

This Karran undermount kitchen sink pairs an equal double-bowl layout with a deep matte black quartz-composite body, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• Equal 50/50 double bowl with matched left and right basins, each 9 inches deep.
• Quartz composite construction made from quartz and acrylic resin for a dense, matte black surface.
• Undermount installation into granite, quartz, or solid surface countertops.
• cUPC and IAPMO certified for plumbing code compliance.
• Requires a 36-inch minimum cabinet width to fit properly.
• 3-1/2-inch drain openings in each bowl for standard drain fittings.

Two Equal Bowls, One Unified Workspace

A 50/50 split gives both bowls the same footprint, so neither side feels like an afterthought. Keep one bowl dedicated to washing and the other open for rinsing produce, soaking a pan, or staging dishes before they go to the drying rack. Because the sink mounts under the counter rather than sitting on top of it, the countertop surface runs uninterrupted to the bowl edge, which makes clearing the counter straightforward and keeps the visual line clean across the installation.

Black Quartz That Holds Its Look

The sink body is quartz composite, an engineered blend of quartz and acrylic resin that gives the surface the density and matte depth of stone without the upkeep demands of natural stone. The black finish reads as a deliberate design decision rather than a default, and the matte surface hides the minor water marks and light surface wear that would stand out on a polished finish. This is not a painted or coated bowl: the color runs through the composite material.

Where This Sink Fits the Project

The black finish makes this sink a strong fit for kitchens designed around contrast, a white or light countertop over a black sink, or an all-dark aesthetic where the sink disappears into the countertop material. Designers specifying a modern, industrial, or high-contrast kitchen will find it an easier call than trying to source a black stainless option. For cabinet shops and contractors, it is worth confirming the countertop fabricator is set up for an undermount on the selected stone or solid surface material before the cabinet goes in. The sink is not ADA compliant as configured.
