A Concrete-Finish Quartz Undermount Sink for Hard-Surface Countertops

This Karran double-bowl undermount sink pairs the warmth of a concrete color with the durability of a quartz-composite body, mounting cleanly beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• Concrete color quartz composite blends a natural, muted tone with the density of a stone-based material.
• Equal 50/50 double bowl splits the basin into two identical sides for separating washing and rinsing tasks.
• Undermount installation into granite, quartz, and solid surface countertops for a seamless counter edge.
• 9-inch bowl depth on each side gives generous clearance for larger cookware and sheet pans.
• cUPC and IAPMO certified for plumbing code compliance in residential and commercial applications.
• Requires a minimum 36-inch base cabinet to accommodate the 32-3/8 by 19-1/4 inch footprint.

Two Equal Bowls for a Divided Workflow

A 50/50 split means neither bowl is sacrificed for the other. Both sides measure the same interior length and width, so a full-size cutting board or a tall stockpot fits just as well on the left as it does on the right. The 9-inch interior depth on each side handles deep pots and tall baking dishes without stacking awkwardly above the rim. This configuration works well in kitchens where two people are often working at the sink at the same time, or where keeping one side clear for prep while the other holds soaking dishes is a daily habit.

Quartz Composite in a Concrete Tone

The concrete finish gives this sink a muted, earthy character that sits comfortably alongside both warm wood tones and cool stone surfaces. It neither reads as a bright white nor competes with a bold black, which makes it a practical choice when the designer wants the sink to recede into the countertop rather than become a focal point. The quartz composite body is a dense, solid material throughout, so the color is not a surface coating that can chip or peel away from a different substrate underneath.

Where This Sink Fits

This sink suits a kitchen remodel or new build where the countertop is being fabricated from granite, quartz, or solid surface. Undermount installation requires a countertop that can support the sink from below and accept a clean-edge cutout, so it is a plan-ahead choice rather than a drop-in replacement for an existing laminate counter. Designers specifying a transitional or industrial-leaning kitchen will find the concrete tone bridges the gap between the warmth of wood cabinetry and the cooler tones of stone or concrete countertops. Builders working on a custom kitchen where the owner wants a distinctive sink color without committing to a high-contrast black or white will find the concrete finish a reliable middle path. The cUPC and IAPMO certifications support specification across a range of residential and light commercial projects.

A Concrete-Tone Undermount That Works in a Real Kitchen

Choose this sink when the job calls for equal double-bowl depth, an undermount install into a hard-surface counter, and a concrete finish that complements stone, wood, or mixed-material kitchens without demanding attention.
