A White Undermount Quartz Sink for a Clean, Bright Kitchen

The Karran QU-720-WH is a double equal-bowl undermount kitchen sink in White, built from quartz composite and designed to mount beneath granite, quartz, or solid surface countertops. Its crisp white finish and flush undermount installation make it a natural fit for kitchens where a bright, uncluttered look is the goal.

Key Features

• White quartz composite construction gives the sink a consistent color and a dense, solid feel throughout.
• Equal 50/50 double bowl keeps washing and rinsing, or prep and cleanup, on separate sides.
• Undermount installation for granite, quartz, and solid surface countertops, with no visible rim at the counter surface.
• cUPC and IAPMO certified for plumbing code compliance in residential kitchen installations.
• 3-1/2 inch drain openings in each bowl to accept standard basket strainers or disposal flanges.
• Requires a minimum 36-inch base cabinet to fit the 33-1/2 by 20-1/2 inch footprint.

Built for the Workhorse Tasks a Kitchen Puts on a Sink

Two equal bowls let the sink handle multiple jobs at once without one side crowding the other. Keep one side clear for rinsing produce or filling pots while the other holds a soaking dish rack or an active prep colander. The undermount design drops the sink rim below the counter surface, so wiping scraps and water directly from the counter into either bowl takes one motion and leaves no lip to catch debris. White reads as neutral in this context: it recedes into the countertop rather than competing with it, and it shows clearly when a bowl needs a rinse.

Quartz Composite in a White Finish

The sink body is quartz composite, a dense material that gives the white finish depth and consistency from the surface down. The matte white surface does not show every water drop the way a polished surface would, and it pairs cleanly with white, light gray, or veined countertops without demanding a color match. Because quartz composite is a manufactured material rather than a coated metal, the color runs through the body rather than sitting on top of it.

Where This Sink Fits

This sink suits new-construction kitchens and full remodels where the countertop is being fabricated alongside the sink. It is an undermount-only design, so the countertop must be cut and finished to accept it from below. Granite, quartz, and solid surface are the supported countertop materials. Homeowners planning a white or light-toned kitchen will find the White finish straightforward to coordinate. Cabinet shops and contractors specifying a kitchen package that leans traditional, transitional, or farmhouse-adjacent will find the white quartz bowl a reliable, broadly compatible choice. The 36-inch minimum base cabinet requirement is the key fit check before ordering.
