A Concrete-Finish Quartz Undermount Sink for a Modern Kitchen

This Karran quartz undermount sink pairs a concrete color with a 60/40 double-bowl configuration, delivering an industrial-modern look in a dense quartz-composite body that mounts beneath granite, quartz, or solid surface countertops.

Key Features

• Concrete color finish brings an industrial-modern palette to a kitchen countertop design.
• 60/40 double-bowl split gives a larger primary basin alongside a smaller secondary bowl for flexible task separation.
• Quartz composite construction from natural quartz and acrylic resin for a dense, consistent body.
• Undermount installation into granite, quartz, or solid surface countertops only.
• cUPC and IAPMO certified for plumbing code compliance.
• Requires a minimum 36-inch base cabinet to accommodate the 32-inch overall width.

Two Bowls, One Concrete-Toned Workhorse

The 60/40 split means the larger bowl handles the heavy-volume work, pots, colanders, and sheet pans, while the smaller bowl stays clear for rinsing produce or filling a pot without giving up the main workspace. That division suits kitchens where a single bowl either crowds out prep or forces constant juggling. The concrete finish keeps the look grounded and neutral, working well alongside matte black hardware, exposed wood shelving, or natural stone countertops where a white or bright sink would read as a visual contrast rather than a complement.

Built From Quartz Composite

The sink body is quartz composite, natural quartz blended with acrylic resin, formed into a dense material that carries its concrete color through the body rather than as a surface coating. The matte, low-sheen character of the concrete finish is consistent with that depth of color. Both bowls share a 9-inch inside depth, giving each basin real capacity regardless of the size difference in their footprints. The 3-1/2-inch drain opening in each bowl is a standard size for most kitchen drain fittings.

Where This Sink Belongs

This is a sink for a kitchen remodel or new build where the countertop is being fabricated new. Undermount installation means the counter must be cut to accept the sink from below, so it is not a drop-in replacement for an existing opening. It mounts into granite, quartz, or solid surface only, not tile or laminate. The 32-inch overall footprint requires a minimum 36-inch base cabinet, which is a common kitchen sink cabinet width but worth confirming before ordering. Designers specifying an industrial or contemporary kitchen palette will find the concrete finish a more neutral anchor than a stark white sink in the same layout. Cabinet shops building kitchen packages can confirm fit against the inside dimensions before the countertop goes to the fabricator.

The Right Concrete Sink for a Countertop Built Around It

Choose this sink when the design calls for a concrete tone that feels deliberate rather than default, backed by a quartz body and certified for code compliance in any kitchen that has the cabinet and countertop to support it.
