Concrete-Finish Quartz Workstation Sink For a Modern Kitchen Build

This Karran single-bowl undermount workstation sink brings an industrial-concrete look to a quartz-composite body, mounting beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• Concrete finish quartz composite delivers an understated industrial tone without the weight or maintenance of real concrete.
• Single deep bowl with a 9-inch inside depth and 30 by 16-3/4 inch interior for generous workstation capacity.
• Undermount installation into granite, quartz, or solid surface countertops for a clean, rimless counter edge.
• Workstation-ready design accommodates compatible accessories for an integrated prep workflow.
• 3-1/2 inch drain opening accepts standard kitchen basket strainers and disposal flanges.
• cUPC certified quartz construction built to North American plumbing standards.

One Bowl Built Around the Work

A single deep bowl keeps the workspace uninterrupted. There is no divider to work around when rinsing a sheet pan, soaking a stock pot, or staging a cutting board across the sink. The workstation ledge runs the perimeter of the bowl, so compatible accessories sit level with the counter rather than resting inside it, letting prep, rinsing, and draining happen in one contained zone. The 9-inch bowl depth gives enough clearance to submerge tall items without water climbing the rim.

Quartz Composite in a Concrete Tone

The sink body is quartz composite, an engineered material that carries the visual weight and density of stone without the porosity of natural concrete. The Concrete finish is a cool, muted gray that reads as raw and industrial, pairing naturally with white oak, dark stained walnut, polished concrete counters, or matte black hardware. Unlike actual poured concrete, the quartz composite surface is non-porous and does not require sealing. The cUPC certification confirms the sink meets North American plumbing code requirements.

Where This Sink Fits

This sink is designed for kitchens where the concrete or industrial aesthetic is intentional, not just a neutral fallback. It suits new builds and full kitchen remodels where the countertop is being fabricated from scratch in granite, quartz, or solid surface. Because it is undermount only, the countertop must be able to support an undermount installation, and the sink requires a minimum 36-inch base cabinet to house the 32-1/2 by 19-3/8 inch footprint. Designers specifying a moody, material-forward kitchen and cabinet shops building for that brief will find the Concrete finish easier to coordinate than a white or bisque option in the same layout.
