Gray Quartz Tone and Compact Undermount Fit

The Karran QX-680-GR is an 18-inch single-bowl quartz undermount sink in gray, sized for bar stations, prep areas, islands, and secondary kitchen workspaces where a full-size bowl would overwhelm the space.

Key Features

• Gray quartz composite construction for a consistent, through-body color that coordinates with gray and neutral countertop palettes.
• Undermount or top-mount installation compatible with all countertop materials.
• Compact 18-inch overall width requiring a minimum cabinet width of 18 inches.
• 7-1/2-inch inside bowl depth with a 3-1/2-inch drain opening.
• cUPC and IAPMO certified for plumbing compliance.

Built for Bar Stations, Islands, and Prep Areas

This sink earns its place in spots where a standard kitchen sink is too large and a utility basin would look out of place. A bar or island prep station with limited cabinet run benefits from an 18-inch footprint that fits within the run without demanding a full base cabinet. The single bowl keeps the workspace clear for rinsing produce, filling pitchers, or handling secondary prep tasks without competing with the main sink.

Gray Quartz Composite Body

The sink is made from quartz composite, which carries the gray color through the material rather than just on the surface. That through-body construction means chips and nicks don't expose a different color underneath. The gray tone reads as a neutral that pairs easily with both warm and cool countertop surfaces, from white quartz to charcoal concrete and most laminates in between. Both undermount and top-mount installations are supported across all countertop materials, so the finish choice doesn't restrict the countertop specification.

Where It Works Best

Cabinet shops and designers specifying a wet bar, a kitchen island, or a laundry-room prep station will find this sink a straightforward fit. The 18-inch minimum cabinet width means it installs into a narrow run without requiring a wider base. Homeowners finishing a bar nook or a butler's pantry where gray is already in the palette will get a coordinated, purpose-built bowl rather than a cut-down workaround. The cUPC and IAPMO certifications satisfy standard residential plumbing requirements without additional documentation.
