A Bisque Quartz Undermount Sink for Bar and Prep Stations

The Karran QU-690-BI is a single-bowl undermount sink in a warm bisque quartz finish, sized for bar, prep, or island installations where a compact square bowl suits the space better than a full kitchen sink.

Key Features

• Bisque quartz composite finish that pairs naturally with cream, almond, and warm-toned kitchen palettes.
• Single square bowl with a 14 by 14 inch interior and 8-1/4 inch depth for generous capacity in a compact footprint.
• Undermount installation into granite, quartz, and solid surface countertops.
• Minimum 21-inch cabinet width required for proper fit and installation clearance.
• 3-1/2 inch drain opening sized for a standard basket strainer or disposal flange.
• cUPC and IAPMO certified quartz composite construction.

Where a Compact Undermount Bowl Gets the Job Done

A 16-5/8 inch square footprint makes this sink a natural fit for a bar cabinet, a kitchen island prep station, or a butler's pantry where counter space is shared with other work. The undermount mount keeps the countertop surface running cleanly to the bowl edge, eliminating the raised rim that collects crumbs and water on a drop-in sink. At 8-1/4 inches deep, the bowl handles produce washing, ice dumping, or prep rinsing without splashing out. This is a working sink for a working station, not a decorative accent.

Quartz Composite in a Warm Bisque Tone

The sink body is quartz composite, an engineered material that gives the bowl the weight and density of stone with a consistent color through the body. The bisque tone sits in the warm off-white range, reading closer to cream than pure white, which allows it to coordinate with natural wood cabinetry, warm-toned countertops, and traditional or transitional kitchen styles where a bright white fixture would feel out of place. The matte quartz surface resists everyday staining and keeps food residue from bonding to the bowl, making routine cleanup straightforward.

Planning the Installation

This sink is designed for undermount installation into granite, quartz, and solid surface countertops. Because the bowl drops below the counter surface, it requires a countertop that structurally supports undermounting, and the opening must be cut to the bowl's 16-5/8 inch square dimension. The minimum cabinet width is 21 inches. This is a sink to plan into a new countertop or a countertop being replaced as part of a remodel. Verify the cabinet width and confirm the countertop material before committing to the install path.
