A Top-Mount Quartz Sink Built for Warm-Toned Kitchens

This Karran QT-670-BI is a single-bowl, top-mount quartz kitchen sink in Bisque, a warm off-white finish that coordinates with cream, ivory, and natural wood kitchens where a stark white sink would read too cool.

Key Features

• Top-mount installation that drops into any countertop material, including laminate, granite, quartz, and solid surface.
• Single bowl with a 9-inch interior depth for soaking large pots and accommodating tall items.
• Quartz composite construction in a Bisque finish for a warm, consistent color throughout the body.
• cUPC and IAPMO certified for compliance with North American plumbing standards.
• 3-1/2-inch drain opening sized to accept standard kitchen drain hardware.
• 33-inch minimum cabinet width required, fitting a standard base cabinet opening.

Where Drop-In Beats Undermount

A top-mount sink installs from above the countertop, resting its perimeter rim on the surface. That approach opens up the countertop materials it can work with: unlike an undermount, this sink drops into laminate, tile, granite, quartz, and solid surface counters without needing a bonded or routed edge. It also slots into an existing cutout during a kitchen refresh, making it the practical choice when the countertop is staying and only the sink is being replaced. The single bowl keeps the interior uninterrupted, so large sheet pans, stockpots, and colanders move in and out without a center divider in the way.

Quartz Composite in a Bisque Finish

The sink body is quartz composite, an engineered material that combines natural quartz with resin binders to produce a dense, non-porous basin. The Bisque colorway runs through the material rather than sitting as a surface coat, so nicks and chips stay inconspicuous. Bisque sits in the warm off-white range, a practical color match for kitchens with cream cabinetry, beige or sand countertops, or natural wood tones where the cooler cast of a white sink would create an unintended contrast. The finish is uniform across the bowl interior and the visible rim.

The Right Fit for This Sink

This sink works well in kitchens undergoing a targeted update: swap the sink without disturbing the counter. It also suits new builds where the countertop material rules out an undermount, or where the designer wants the rim visible as part of the surface detail. The 33-inch width and 9-inch depth make it a full-function primary kitchen sink rather than a secondary prep bowl. It is not ADA compliant, so specify accordingly for accessible design projects.
