Karran Quartz Undermount Sink for a Concrete-Finish Kitchen

This Karran quartz undermount kitchen sink pairs a 60/40 double-bowl layout with a concrete finish, mounting beneath granite, quartz, or solid surface countertops for a seamless, modern installation. It is cUPC and IAPMO certified and requires a 36-inch minimum cabinet width.

Key Features

• Concrete finish in a quartz composite body, one of seven colors in the line.
• 60/40 double-bowl configuration with a larger left basin and a smaller right basin for task separation.
• Undermount installation into granite, quartz, or solid surface countertops.
• cUPC and IAPMO certified for plumbing code compliance.
• 3-1/2 inch drain opening in both bowls.
• 36-inch minimum cabinet width required for proper fit.

Two Bowls, One Clear Workflow

The 60/40 split gives you two distinct workspaces rather than two equal halves. The larger left bowl handles the bulk of the work, whether that is washing a full load of dishes, soaking a roasting pan, or prepping produce. The smaller right bowl stays free for rinsing, draining, or keeping a second task running in parallel. That asymmetry makes the layout practical in a working kitchen where the sink gets daily, varied use rather than serving one function at a time.

Quartz Composite in Concrete

The sink is built from quartz composite, the dense engineered material that carries the look and weight of stone while remaining consistent in color from the surface down. The concrete finish reads as a cool, textured neutral that works with both light and dark countertop colors without competing with either. It pairs naturally with the industrial and transitional kitchen styles where concrete tones have become a deliberate design choice rather than an afterthought. Unlike a polished or high-gloss surface, the concrete finish keeps everyday water marks and minor wear from standing out under kitchen lighting.

Where This Sink Belongs

This is a sink for a kitchen remodel or new build where the countertop is being fabricated at the same time. Undermount installation requires the countertop to be cut and finished to the bowl edge, so the concrete finish and the counter material work as a coordinated surface. It installs into granite, quartz, and solid surface countertops. The 36-inch cabinet minimum means it fits standard 36-inch base cabinets but not narrower configurations, so confirm the base before ordering. Designers specifying a transitional or industrial kitchen will find the concrete tone a straightforward fit; contractors and cabinet shops sourcing for a complete kitchen build can pair it with coordinating countertop slabs without the finish fighting the stone.
