A 32-1/2 Inch Single-Bowl Undermount Sink for Modern and Industrial Kitchens

This Karran quartz single-bowl undermount sink delivers a Concrete finish that anchors contemporary, industrial, and mixed-material kitchen designs. It mounts beneath quartz, granite, or solid surface countertops and carries cUPC certification for installation in residential and commercial projects.

Key Features

• Concrete quartz composite finish brings a muted, stone-like tone suited to modern and industrial kitchen aesthetics.
• Single 30 x 16-3/4 inch interior bowl at 9 inches deep provides an uninterrupted basin for washing large cookware.
• Undermount installation into quartz, granite, or solid surface countertops keeps the counter surface clean and seamless.
• Requires a minimum 36-inch cabinet to accommodate the 32-1/2 inch overall width.
• cUPC certified for residential and commercial plumbing installations.
• 3-1/2 inch drain opening accepts standard kitchen strainer fittings.

One Deep Bowl for a Full Kitchen Workload

A single wide bowl at 9 inches deep handles the tasks a divided sink cannot: soaking a large stock pot, washing a sheet pan flat, or bathing a cutting board without splitting it across two basins. The 30-inch interior length gives enough runway for anything a serious cook or a busy kitchen crew puts in it. Because there is no divider, cleanup moves in one continuous motion from one end to the other.

Quartz Composite in Concrete

The sink is built from quartz composite, a dense engineered material that resists the stresses of daily kitchen use. The Concrete finish reads as a warm gray-toned neutral, sitting close to raw concrete in tone without the maintenance of actual poured surfaces. It coordinates naturally with white oak cabinetry, raw metal hardware, dark countertops, and the broader palette of industrial and Scandinavian-influenced kitchens. Because the color runs through the composite material rather than sitting on the surface as a coating, chips and wear do not expose a contrasting core.

Where This Sink Fits Best

This is the sink for a kitchen where the hardware, cabinet fronts, and countertop are leaning toward a cooler, more restrained palette. Designers specifying a concrete-look kitchen without the weight and maintenance commitment of actual concrete countertops will find the Concrete quartz finish pairs well with engineered stone surfaces in similar tones. Cabinet shops building frameless kitchens around a 36-inch sink base can plan around the minimum cabinet width requirement. Contractors working a remodel that includes a new countertop fabrication can specify the undermount detail and deliver a finished look with no visible rim at the counter edge. Because this is an undermount sink, it requires countertop fabrication as part of the installation, making it the right call for a new build or a full counter replacement rather than a swap into an existing drop-in cutout.
