Karran Quartz Undermount Sink For an Industrial or Contemporary Kitchen

This Karran quartz double-bowl undermount sink brings a raw, concrete-toned finish to a 50/50 equal-bowl basin designed to mount beneath quartz, granite, or solid surface countertops. The Concrete color suits kitchens where the palette leans toward gray-toned stone, poured-concrete aesthetics, or darker cabinetry.

Key Features

• Concrete color quartz composite pairs a neutral gray-toned finish with the density and weight of a stone-like material.
• Equal 50/50 double bowl gives two separate basins of identical depth and width for flexible task separation.
• Undermount installation into granite, quartz, or solid surface countertops keeps the counter edge clean and uninterrupted.
• Requires a 36-inch minimum cabinet width to accommodate the full 32-3/8 by 19-1/4 inch footprint.
• 3-1/2 inch drain opening in each bowl, sized for standard waste fittings.
• cUPC and IAPMO certified for code compliance across most residential and commercial installations.

Two Equal Bowls, One Clean Counter Edge

Equal-split double-bowl sinks work well where tasks naturally divide: one side for washing, the other for rinsing, or one for prep while the other stays clear for clean dishes. Because this sink mounts under the counter rather than dropping in from above, there is no visible rim breaking up the countertop surface. Crumbs and water wipe straight from the counter into the bowl without a lip to catch them. Each bowl measures 14-1/4 inches long, 16-3/4 inches wide, and 9 inches deep, giving substantial capacity on both sides.

A Quartz Composite Built for Daily Use

The sink is made from quartz composite, an engineered material that gives the surface a consistent color and a matte, stone-like texture throughout. The Concrete finish reads as a warm gray with natural variation, similar in tone to poured concrete or certain honed stone surfaces. It holds up to the demands of a working kitchen without showing every water spot or scratch the way a polished surface would. Installation suits granite, quartz, and solid surface countertops — these are the countertop types that support proper undermounting. The sink is not designed to top mount or to drop into an existing cutout made for a different sink, so plan it into a new countertop fabrication.

Where This Sink Fits Best

This is the right sink for a kitchen renovation or new build where the design is leaning toward industrial, modern, or Scandinavian aesthetics — spaces where concrete, raw steel, and matte stone finishes are already in the palette. A cabinet shop or contractor speccing a complete kitchen will want to confirm the base cabinet is at least 36 inches wide and that the countertop material is granite, quartz, or solid surface before ordering. Designers working on high-contrast kitchens, dark cabinetry, or light gray countertops will find the Concrete finish coordinates well without competing with stone-toned counters. Homeowners replacing an existing sink should verify that this is a new-countertop installation rather than a swap into an existing cutout.
