Concrete-Finish Quartz Sink for an Undermount Double-Bowl Kitchen

This Karran quartz undermount sink pairs an equal 50/50 double-bowl layout with a Concrete finish, mounting beneath granite, quartz, or solid surface countertops in cabinets 36 inches wide or larger.

Key Features

• Concrete color finish on a quartz composite body for an industrial-modern look that coordinates with stone and concrete-look countertops.
• Equal 50/50 double bowl at 33-1/2 inches wide by 20-1/2 inches deep, with 9-inch bowl depth on both sides.
• Undermount installation into granite, quartz, or solid surface countertops.
• Requires a 36-inch minimum cabinet width for proper fit and mounting.
• 3-1/2 inch drain opening on each bowl, sized for standard strainer fittings.
• cUPC and IAPMO certified quartz composite construction.

Two Equal Bowls, One Clean Countertop Line

Equal-split double bowls let you dedicate one side to washing and the other to rinsing or prep, keeping both tasks in reach without a basin size compromise. Because this sink mounts under the counter, the countertop surface runs continuously to the bowl edge with no rim or flange on top. That unbroken line makes wiping water and crumbs directly into the sink straightforward, and the Concrete finish tucks cleanly under darker stone slabs or concrete-look laminate where a white or bright bowl would read as a mismatch.

Quartz Composite in a Concrete Finish

The sink body is quartz composite, a dense material that resists the everyday knocks and heat swings of active kitchen use. The Concrete color finish gives the bowls a matte, neutral-gray surface that reads as intentional next to raw concrete countertops, dark soapstone-look quartz, or industrial tile, rather than a workaround for a color that was hard to find. Both bowls share the same 9-inch depth, so neither side trades usable volume for symmetry.

Where This Sink Fits

This is a sink for a kitchen where the Concrete finish is a design choice, not a neutral fallback. It suits new builds and full remodels where the countertop is being fabricated from the start, because undermount installation requires the counter to be prepared for it. The sink fits granite, quartz, and solid surface countertops and needs a base cabinet at least 36 inches wide. It carries cUPC and IAPMO certification, so it meets plumbing code requirements in the jurisdictions those marks cover. Designers specifying industrial or contemporary kitchens and cabinet shops building out those projects will find the finish ready to coordinate without special ordering.
