A Clean White Single-Bowl Undermount Sink for Solid Countertops

This Karran quartz kitchen sink is a single-bowl undermount designed to mount beneath granite, quartz, or solid surface countertops and deliver a seamless, low-profile look in a bright white finish.

Key Features

• Single-bowl configuration with a 9-inch interior depth for generous capacity in one uninterrupted basin.
• Quartz composite construction in a White finish that coordinates with white and light-toned countertop and cabinetry schemes.
• Undermount installation into granite, quartz, or solid surface countertops, keeping the counter edge flush to the bowl rim.
• Minimum 36-inch cabinet width required for proper fit and support.
• 3-1/2 inch drain opening compatible with standard kitchen strainers and disposal flanges.
• cUPC certified for use in residential plumbing installations.

One Deep Basin, Unobstructed

A single-bowl sink clears the divider out of the way entirely, which makes it easier to wash large sheet pans, stockpots, and cutting boards that would bridge or jam against a center partition. The 9-inch interior depth keeps water contained and provides headroom for soaking. This is the layout that works best for kitchens where volume cooking or large-format cleanup is a regular part of the routine.

White Quartz in a Clean Undermount Profile

The White finish on this quartz composite sink suits kitchens built around white cabinetry, light stone countertops, or a bright, airy palette. Because the sink mounts from below, the countertop surface runs unbroken to the bowl edge with no rim or lip to interrupt the line. The quartz composite body holds color consistently through the material, so the white reads as a solid, uniform tone rather than a surface coating.

Where This Sink Fits

This is a primary kitchen sink for new construction or a countertop replacement where the counter is being fabricated fresh. It is designed to undermount into granite, quartz, or solid surface only, and it requires a countertop being built new around it rather than dropping into an existing cutout. It needs a 36-inch or wider base cabinet to support the 32-1/2 inch overall width. Designers specifying white-on-white kitchen schemes and homeowners remodeling around a bright, neutral palette will find the White finish straightforward to coordinate. The cUPC certification satisfies the residential plumbing code requirements that inspectors check on new installs.
