A 33-1/2 Inch Single-Bowl Undermount Sink for Concrete-Look Kitchens

This Karran quartz undermount kitchen sink brings an industrial concrete finish to a full-sized single-bowl basin that mounts cleanly beneath quartz, granite, or solid surface countertops. It ships as a kit and carries cUPC and IAPMO certifications.

Key Features

• Concrete finish quartz composite for an industrial, raw-material look in a kitchen context.
• Single bowl configuration with a 31 inch interior length and 9 inch depth for generous workspace.
• Undermount installation into granite, quartz, or solid surface countertops.
• Requires a minimum 36 inch base cabinet for proper fit and support.
• 3-1/2 inch drain opening compatible with standard kitchen drain fittings.
• cUPC and IAPMO certified quartz composite construction.

One Basin Built for Kitchen Workflow

A deep single bowl gives uninterrupted space for large pots, sheet pans, and oversize cutting boards that a divided sink cannot handle. The 9 inch interior depth keeps splashing contained, and the full 31 inch interior length means there is room to soak, rinse, and stage without crowding. This sink suits any kitchen where a single, spacious workspace is more useful than splitting the basin in two.

The Concrete Finish in Quartz Composite

The Concrete finish reads as a muted, stone-grey tone that works with the raw, industrial palette common in contemporary and transitional kitchens — concrete countertops, exposed metal hardware, matte cabinetry, and similar material combinations. Unlike actual concrete, the quartz composite body is non-porous, which means it does not require sealing and resists picking up stains from daily kitchen use. The material is a quartz composite, and the Concrete color is consistent through the body rather than a surface coat.

Where This Sink Fits

Designers and contractors specifying a kitchen with an industrial or raw-material aesthetic will find the Concrete finish pairs naturally with matte black faucets, open shelving, and stone or engineered stone countertops. Homeowners renovating with a concrete-look countertop can use this sink to carry the palette into the basin itself without the maintenance demands of cast concrete. Because it is an undermount, it is best suited to new countertop installations where the cutout can be fabricated to the sink's exact footprint. The 36 inch minimum cabinet width is the critical fit check before ordering.
