A White Drop-In Quartz Sink That Works With Any Countertop

This Karran quartz top-mount kitchen sink drops into any countertop material and delivers a clean white finish with a split-bowl layout sized for everyday kitchen workflow.

Key Features

• Top-mount installation compatible with all countertop materials, including laminate, quartz, solid surface, and granite.
• 60/40 double bowl split with a larger primary basin and a smaller secondary basin for flexible task separation.
• White quartz composite construction with a consistent color and a dense, non-porous body.
• 3-1/2 inch drain openings sized for standard kitchen strainers and disposal flanges.
• cUPC and IAPMO certified for code compliance across North American installations.
• Requires a minimum 33-inch cabinet to accommodate the full 33 by 22 inch footprint.

Two Bowls, One Sink, One Smooth Install

The 60/40 bowl split gives the primary side enough room to handle a full load of dishes while keeping the smaller side free for rinsing produce, draining pasta, or staging prep. That task separation is where a split-bowl sink earns its place over a single bowl or an equal double — you never have to choose between washing and rinsing at the same time.

Top-mount installation means the sink rim rests on the countertop surface, supported by the perimeter flange. Because it drops in from above rather than bonding beneath the counter, it fits wherever the cutout lands, whether that is a laminate counter in a rental remodel, a solid surface in a new build, or a stone top in a high-end kitchen. No special countertop fabrication is required beyond a standard cutout to the sink's dimensions.

Quartz Composite in Classic White

White is the finish choice that matches the widest range of cabinet and countertop colors without requiring coordination. It reads neutral against both warm wood tones and cooler painted or painted-and-glazed cabinet finishes, making it the practical default for designers specifying a kitchen that needs to hold up across a long remodel timeline or a multi-unit build.

The sink body is quartz composite, which gives it more density and heft than acrylic and a color that runs through the material rather than sitting only at the surface. The non-porous construction keeps food residue from soaking in, and the white finish shows even water spots less than a polished surface would.

Where This Sink Fits

This sink is a strong match for remodels where the countertop is staying in place, because a top-mount sink installs without disturbing the counter material underneath. It also suits new construction where laminate countertops are specified, since laminate does not support undermounting. Designers and cabinet shops specifying kitchens for multi-family or rental builds will find the top-mount format and white finish together cover the broadest range of countertop combinations without custom fabrication.

It requires a base cabinet of at least 33 inches wide. Because it is not ADA compliant, it is not the right choice for an accessibility-focused kitchen layout.
