Karran Quartz Undermount Sink for a Black-Accent Kitchen

This Karran quartz kitchen sink is a 60/40 double-bowl undermount model in Black, designed to mount beneath quartz, granite, or solid surface countertops in a 36-inch or wider cabinet.

Key Features

• 60/40 double bowl configuration gives a larger primary bowl for washing and a smaller secondary bowl for rinsing or prep.
• Quartz composite construction built from natural quartz and acrylic resin for a dense, heavy-duty body.
• Matte Black finish with consistent color throughout the composite material.
• Undermount installation into granite, quartz, or solid surface countertops only.
• Requires a 36-inch minimum cabinet width to accommodate the 32-inch overall sink length.
• cUPC and IAPMO certified for residential plumbing code compliance.

Two Bowls, One Clear Purpose

The 60/40 split gives you an unequal pair: a larger left bowl at 15-1/4 inches long for full-sized pots and stacked dishes, and a smaller right bowl at 12-3/4 inches for rinsing produce, staging a colander, or keeping a second task running while the main bowl is in use. Both bowls share a 9-inch inside depth, so neither side feels shallow. This split is the choice when one bowl handles the heavy daily load and the other stays available for secondary work, rather than dividing everything evenly between two equal halves.

Quartz Composite in a Deep Matte Black

The sink body is quartz composite, a blend of natural quartz and acrylic resin that produces a solid, non-porous surface. The Black finish runs through the material rather than sitting as a surface coating, so chips and wear do not expose a different color underneath. The matte surface keeps water spots and fingerprints from reading as prominently as they would on a polished or gloss finish, an advantage in a working kitchen where a sink gets handled all day. This sink carries cUPC and IAPMO certifications, meeting the plumbing code standards most jurisdictions require.

Where This Sink Belongs

The Black finish is the lead design decision here. This sink is the right call for kitchens built around a dark or two-tone palette: matte black hardware, dark cabinetry, or black-veined countertops where a white or neutral sink would break the look rather than complete it. Designers specifying a bold, intentional kitchen aesthetic and homeowners renovating toward a modern or industrial feel both reach for this finish. Because it is an undermount model, it suits a new countertop fabrication rather than a drop-into-existing-cutout replacement. The sink needs a granite, quartz, or solid surface counter and a base cabinet at least 36 inches wide. It is not ADA compliant, so it does not apply where accessibility requirements are in play.
