A White Quartz Undermount Sink for a Clean, Seamless Kitchen

This Karran single-bowl undermount sink is a 32-inch quartz composite kitchen sink in White, designed to mount beneath granite, quartz, or solid surface countertops for a flush, uninterrupted counter surface.

Key Features

• White quartz composite construction with a consistent color and matte surface throughout the bowl.
• Single bowl at 30 x 16-1/4 x 9 inches (inside dimensions) for unobstructed washing and soaking capacity.
• Undermount installation into granite, quartz, or solid surface countertops, keeping the counter edge clean and uninterrupted.
• Fits a 36-inch minimum cabinet width with a 3-1/2 inch drain opening.
• cUPC and IAPMO certified for plumbing code compliance in the US and Canada.

One Deep Bowl, No Divider

A single-bowl sink trades the divider of a split configuration for one open, unobstructed basin. The 9-inch interior depth handles tall stockpots, sheet pans, and large cutting boards that would bridge or overhang a divided sink. It also leaves the full width free when washing larger items in a single pass. White suits kitchens where the sink and counter read as one continuous surface, particularly when the countertop is a light quartz or white solid surface.

Quartz Composite Built for Kitchen Use

The sink is made from quartz composite, a dense material that combines the look and weight of stone with the consistency of an engineered product. White runs uniform through the material, so the color holds even along the rim and bowl walls where surface wear would show on a coated finish. The matte surface keeps water spots and minor scratches from catching the light the way a polished surface would. Mounting beneath the countertop means the quartz composite rim bonds directly to the underside of the slab, with no exposed edge or lip sitting above the counter to collect debris.

Where This Sink Fits

This is the right sink for a primary kitchen installation where the counter is being fabricated new or replaced, and where a single large bowl suits the cooking and cleanup workflow. It works especially well in kitchens built around light countertop materials such as white quartz or light granite, where a white sink disappears into the surface rather than contrasting with it. Cabinet shops and remodelers building out a 36-inch or wider sink base should verify the 32 x 19-1/2 inch footprint against the rough opening before the counter is cut. Because it is undermount only, it is not suited to drop-in or tile-on countertop applications.
