A White Quartz Undermount Sink for Clean-Line Kitchen Builds

This Karran single-bowl undermount sink delivers a wide, deep basin in a bright white quartz composite, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• Single bowl, deep basin with a 9-inch interior depth for large pots, sheet pans, and full-size colanders.
• Quartz composite construction that gives the sink solid heft and a consistent white color throughout the body.
• White finish that reads clean against white cabinetry, marble-look counters, and light-toned kitchen palettes.
• Undermount installation into granite, quartz, or solid surface countertops for an unbroken counter surface.
• cUPC and IAPMO certified, meeting North American plumbing standards.
• 3-1/2 inch drain opening sized for standard kitchen strainers and disposal flanges.

One Wide Bowl for Kitchen Workflow

A single uninterrupted basin this size keeps large items from getting wedged against a divider. A full sheet pan, a tall stockpot, or an oversized cutting board slides in without a center divider to work around. The 9-inch interior depth keeps splashing in the bowl and leaves room to submerge deep items fully. This sink suits a primary kitchen station where the work is real and the volume is high.

Quartz Composite in a Bright White Finish

The sink is built from quartz composite, a dense material that brings weight and rigidity without the fragility of ceramic. White is the finish here, a true, consistent white that holds its appearance against white shaker cabinets, bright subway tile, or countertops in Calacatta, Carrara, or similar light-toned patterns. Because the color runs through the quartz composite body rather than sitting only on the surface, small nicks and chips do not expose a contrasting core underneath.

Where This Sink Fits Best

This sink is at home in a kitchen renovation or new build where the designer or homeowner is working in a light, clean palette and needs a primary sink with serious capacity. Designers specifying for white or off-white kitchens will find that a white quartz basin integrates more naturally than a stainless bowl or a darker composite. Cabinet shops building frameless or face-frame kitchens around a 36-inch base will find the 33-1/2 by 21-inch footprint fits squarely within that opening. Because it is an undermount, it requires a countertop material that supports undermounting, specifically granite, quartz, or solid surface fabricated to accept the sink before installation. This is not a drop-in replacement for an existing cutout.

Common Questions

The Right Basin for a White Kitchen

Choose this sink when the palette calls for white, the workload calls for a single deep bowl, and the countertop is granite, quartz, or solid surface built to accept an undermount.
