A White Quartz Undermount Sink for Kitchens That Work Two Tasks at Once

This Karran quartz undermount sink delivers a 60/40 split double-bowl configuration in a bright white finish, designed to mount beneath granite, quartz, or solid surface countertops in a 36-inch or wider base cabinet.

Key Features

• 60/40 split double-bowl layout gives a larger primary basin alongside a smaller secondary bowl for separating wash and rinse, or prep and cleanup tasks.
• White quartz composite material pairs a clean, bright look with the density and consistent coloring of a quartz body.
• Undermount installation into granite, quartz, or solid surface countertops for a seamless counter-to-bowl transition.
• Requires a minimum 36-inch base cabinet to accommodate the 33-1/2 inch side-to-side footprint.
• 3-1/2 inch drain opening in each bowl to accept standard drain fittings.
• cUPC and IAPMO certified for code compliance in residential and commercial plumbing applications.

Two Bowls, One Unbroken Counter Edge

The 60/40 split puts more of the sink's width into the primary bowl, which handles the bulk of dishwashing and soaking, while the smaller secondary bowl stays clear for rinsing produce, draining pasta, or keeping a second prep area separate. Because the sink mounts from below, the countertop surface runs continuously to the bowl edge with no exposed rim to trap debris or interrupt wiping down the counter. That clean line is one of the main reasons this configuration shows up in kitchens where countertop appearance is part of the design intent.

Quartz Composite in White

White is a natural fit for kitchens built around light cabinetry, bright stone countertops, or a clean, consistent palette. This sink's quartz composite body holds its color uniformly throughout the material, so chips or minor surface wear do not expose a different color underneath. The quartz makeup also gives the sink the heft and thermal mass associated with stone sinks, and each bowl shares the same 9-inch inside depth for full working room. The white finish coordinates easily with stainless faucets, brushed nickel, and chrome fixtures alike.

Planning the Installation

This sink is designed for kitchens where a new countertop is part of the project. It mounts beneath granite, quartz, or solid surface slabs, and is not intended for drop-in use or for retrofit into an existing cutout sized for a different sink. The 33-1/2 by 20-5/8 inch footprint requires a 36-inch minimum cabinet width. Designers specifying a white sink to coordinate with a light stone or quartz countertop field will find the color reads as clean and integrated rather than contrasting. Cabinet shops and contractors planning a new build or full remodel where the cabinet and counter are being set together are the natural fit for this sink.
