A White Quartz Double-Bowl Sink for a Clean, Seamless Kitchen Install

This Karran undermount kitchen sink is a 50/50 double-bowl quartz sink in White, designed to mount beneath granite, quartz, or solid surface countertops and fit cabinets 36 inches wide or larger.

Key Features

• Equal 50/50 double bowl with two identically sized basins for separating washing and rinsing or prep and cleanup.
• White quartz composite construction with a non-porous surface that resists staining and everyday kitchen wear.
• Undermount installation into granite, quartz, or solid surface countertops.
• Requires a minimum 36-inch cabinet for a proper fit.
• cUPC and IAPMO certified for use in plumbing installations.
• 9-inch bowl depth on both sides for comfortable washing clearance.

Two Equal Bowls Under a Clean Counter Edge

Because this sink mounts from beneath the countertop, the counter surface runs unbroken right to the bowl edge with no visible rim to collect debris or water. White works especially well in that application: the bowl blends naturally with light-toned countertops and reads as part of the surface rather than a fixture dropped into it. The equal 50/50 split means both sides are the same depth and width, so neither bowl feels like an afterthought. One side handles soaking or a rack of dishes while the other stays clear for rinsing produce or a cutting board.

Quartz Composite Material and Finish

The sink is built from quartz composite, a dense engineered material that gives the bowl a consistent color and a smooth matte surface that holds up to daily use. The White finish is uniform throughout the material, so chips or scratches at the bowl edge do not expose a different color underneath. The non-porous surface resists staining and keeps food residue from bonding to the bowl, which simplifies cleanup after a busy meal. Both bowls measure 9 inches deep, giving enough clearance for tall stock pots without the basin feeling cavernous.

Planning Your Installation

This sink is undermount only and is designed to bond under new granite, quartz, or solid surface countertops. It is not intended for drop-in installation, and it is not suited to drop into an existing countertop that already has a cutout sized for a different sink. Plan it into a countertop fabrication project, either a new build or a remodel where the counter is being replaced. The 32-3/8 by 19-1/4 inch footprint fits a 36-inch base cabinet, which is the minimum cabinet width required. Confirm the cabinet dimensions and the countertop fabrication plan before ordering. The kit is cUPC and IAPMO certified, which satisfies the plumbing code requirements in most jurisdictions.
