Concrete Finish and a 60/40 Split That Matches the Way Kitchens Actually Work

This Karran quartz undermount kitchen sink pairs a muted concrete finish with an unequal double-bowl layout, giving the larger bowl room for washing bulky pots while the smaller bowl stays free for rinsing or prep. It mounts beneath quartz, granite, or solid surface countertops and is IAPMO certified.

Key Features

• 60/40 unequal double-bowl layout with a deeper large bowl and a dedicated smaller bowl for simultaneous tasks.
• Concrete color finish in a quartz-composite body for a muted, industrial-leaning tone that coordinates with modern and transitional kitchens.
• Undermount installation designed for quartz, granite, and solid surface countertops.
• Requires a minimum 36-inch base cabinet to fit the 32-inch overall width.
• 3-1/2 inch drain openings in both bowls, a standard size for kitchen strainers and disposal flanges.
• IAPMO certified quartz composite construction.

Two Bowls Sized for Real Kitchen Workflows

The 60/40 bowl split gives the large bowl more real estate for soaking a sheet pan or washing a dutch oven, while the smaller bowl stays available for draining pasta, rinsing produce, or holding a colander. That division of labor is where the unequal split earns its keep over a 50/50 layout in a working kitchen. Both bowls sit at 9 inches deep, so neither is shallow.

Undermounting keeps the countertop surface continuous from the edge straight to the bowl, which makes wiping crumbs and liquid off the counter a one-motion job. There is no rim to scrub around or for water to pool against.

Quartz Composite in a Concrete Finish

The sink is made from quartz composite, an engineered material that gives the bowl a dense, stone-like feel and consistent color throughout. The concrete finish reads as a warm neutral gray with a slightly textured, matte character. It sits comfortably in kitchens built around white oak cabinetry, dark stone countertops, matte hardware, or exposed concrete surfaces, and it does not compete visually with busy tile or patterned countertops the way a glossy white or bright-colored sink can.

Quartz composite is a non-porous material, so food residue and liquids do not penetrate the surface. The finish holds its tone over daily use without needing special care products.

Where This Sink Fits

This is a sink for a primary kitchen installation where the countertop is new or being replaced as part of a remodel. Undermount sinks require the countertop to be fabricated around them, so this is not the right choice for dropping into an existing cutout. Because it demands a 36-inch minimum base cabinet, it suits standard full-size kitchen runs rather than islands or prep stations with narrower cabinetry.

The concrete finish makes it a natural match for modern, industrial, or transitional kitchens where hardware and fixtures lean toward matte blacks, unlacquered brass, or brushed metals. Designers specifying a cohesive neutral palette will find the tone easier to coordinate than a bright color or a stark white. Cabinet shops building for remodels can spec this alongside frameless or face-frame base cabinets in the 36-inch class with equal confidence.
