A Concrete-Finish Quartz Sink That Grounds a Modern Kitchen

This Karran Q-350-CN is a double equal-bowl undermount kitchen sink in a Concrete finish, built from a quartz composite body and designed to mount beneath laminate, solid surface, or granite countertops.

Key Features

• Concrete finish quartz composite gives this sink the muted, industrial tone that reads well against both light and dark countertops.
• Equal 50/50 double bowl splits the basin into two identical sides for keeping tasks separate.
• Undermount installation into laminate, solid surface, or granite countertops.
• 33-inch minimum cabinet width required for proper fit and installation.
• 8-1/2-inch bowl depth accommodates large pots and full-size sheet pans.
• cUPC and IAPMO certified quartz sink body.

Two Equal Bowls, One Integrated Look

An equal double-bowl layout keeps workflow organized without sacrificing basin size on either side. One bowl can hold soaking dishes while the other stays clear for rinsing or active food prep. Because this sink mounts under the countertop rather than dropping in from above, the counter surface meets the bowl edge cleanly, with no rim collecting crumbs or pooling water. That seamless transition is a practical advantage on a busy cooktop-to-sink run and reinforces the clean visual line a modern kitchen depends on.

Quartz Composite in a Concrete Finish

The Concrete finish is a muted gray-brown tone that sits between warm and cool, pairing naturally with concrete-look countertops, light wood cabinetry, dark matte hardware, and the current wave of industrial-influenced kitchen design. The quartz composite body is dense and consistent in color through the material, so the finish does not chip away to reveal a different substrate underneath. Certifications from cUPC and IAPMO confirm the sink meets North American plumbing standards.

Where This Sink Fits Best

This is the right choice for a new kitchen build or a full countertop replacement where the designer or homeowner wants a sink finish that does more visual work than basic white or stainless. Cabinet shops and contractors specifying a contemporary or transitional kitchen will find the Concrete finish a strong fit with engineered stone looks, leathered granite, and solid surface materials. Because it is an undermount, it is designed for new countertop fabrication and does not drop into an existing cutout. The 33-inch minimum cabinet width is the key fitment check before ordering.

Common Questions

A Finish That Does the Design Work

Choose this sink when the goal is a kitchen where the sink contributes to the aesthetic rather than disappearing into it, and the countertop is being fabricated new to accept an undermount installation.
