Karran Quartz Undermount Sink For a Clean White Kitchen

This Karran quartz kitchen sink is a 60/40 split double-bowl undermount sink in White, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• 60/40 double bowl split gives you a larger bowl for washing and a smaller bowl for rinsing or prep work.
• Quartz composite material made from natural quartz and acrylic resin for a dense, matte-surface basin.
• Undermount installation into granite, quartz, or solid surface countertops only.
• White finish with a consistent matte surface that reads clean against white or light-colored countertops.
• cUPC and IAPMO certified for plumbing code compliance.
• 3-1/2 inch drain opening in each bowl, sized for standard kitchen strainers.

Two Bowls, Two Jobs

A 60/40 split means the two bowls are not equal: the larger left bowl handles washing full-sized pots and sheet pans, while the smaller right bowl stays available for rinsing produce, draining pasta, or staging a second task without clearing the main bowl first. That division keeps kitchen workflow moving in a way a single bowl or equal split sometimes cannot. Because it is an undermount, the countertop surface runs cleanly to the basin edges with no rim or flange collecting water and crumbs along the top edge.

Quartz Composite in White

The sink is built from natural quartz blended with acrylic resin, a composite that produces a solid, matte bowl surface rather than a polished one. White is the finish here, and its consistent color runs through the material rather than sitting only at the surface, so chips or scuffs at the rim do not expose a different color underneath. The matte white surface pairs naturally with white subway tile, white shaker cabinets, and light quartz or solid surface countertops where a sink rim visible above the counter would break the look.

Where This Sink Fits

This sink is the right choice for a kitchen remodel or new build where the countertop is being fabricated new. It requires a 36-inch minimum cabinet width and is designed for undermount installation only into granite, quartz, or solid surface countertops. It is not intended for laminate or tile counters and cannot be dropped into an existing cutout made for a different sink. Designers specifying a white-on-white kitchen and contractors setting sinks into stone or engineered countertops will find this a straightforward, code-compliant choice. The cUPC and IAPMO certifications satisfy the plumbing code requirements most jurisdictions require at rough inspection.
