Karran Quartz Bar and Prep Sink for a Concrete-Finish Counter

This Karran QX-680-CN is a single-bowl quartz undermount sink in a Concrete finish, sized for bar, island prep, and secondary workstation installations where a full kitchen sink would be too much.

Key Features

• Concrete finish quartz composite that pairs naturally with raw, industrial, and mixed-material counter designs.
• Undermount or top-mount installation compatible with all countertop materials.
• Single bowl configuration with a 14 inch by 9 inch interior and 7-1/2 inch depth.
• 18 inch minimum cabinet width required, making it a compact fit for bar and island base cabinets.
• cUPC and IAPMO certified quartz construction.
• 3-1/2 inch drain opening for standard strainer and disposal flange compatibility.

Built for Bar and Prep Stations

A secondary sink earns its place by staying out of the way of the main kitchen workflow while handling rinsing, bar prep, and quick washups on its own. At 18 inches wide, this single bowl fits where a larger sink cannot: an island end cabinet, a wet bar run, or a narrow prep alcove. The 7-1/2 inch bowl depth is enough for washing produce and mixing glasses without the footprint of a full kitchen basin.

The Concrete Finish in Quartz Composite

The Concrete color reads like a neutral, weathered gray, closer to poured concrete than to a cool-toned grey or a warm putty. It suits counters that lean industrial, counters paired with open shelving and matte black fixtures, and mixed-material kitchens where a warmer neutral finish would feel out of step. The sink body is quartz composite, a dense material that holds its color through the full thickness of the bowl.

Where This Sink Works

This is the right size for a bar base cabinet, a kitchen island prep station, or a butler's pantry secondary sink. Because it is compatible with all countertop materials and accepts both undermount and top-mount installation, it fits most build and remodel situations without requiring a specific countertop substrate. Designers specifying for a wet bar with a concrete or raw-finish countertop will find the Concrete color integrates without requiring a finish match. Cabinet shops and contractors building out islands can size the base cabinet to the 18 inch minimum width and keep the overall footprint tight.
