A White Quartz Undermount Sink Built Around an Uneven Split

This Karran quartz kitchen sink pairs a larger primary bowl with a smaller secondary bowl in a 60/40 configuration, all in a clean white finish that undermounts beneath granite, quartz, or solid surface countertops.

Key Features

• 60/40 double-bowl layout gives you a larger primary side for washing and a smaller secondary side for rinsing or prep.
• White quartz composite construction built from 80% quartz blended with acrylic resin for a dense, consistent body.
• Undermount installation into granite, quartz, or solid surface countertops, requires a minimum 36-inch base cabinet.
• Both bowls measure 9 inches deep for comfortable pot washing and soaking without a shallow compromise on either side.
• cUPC and IAPMO certified for plumbing code compliance across North America.
• 3-1/2 inch drain openings in each bowl for standard basket strainer compatibility.

Why the 60/40 Split Works in a Working Kitchen

An equal 50/50 double bowl gives you symmetry. A 60/40 split gives you a clear primary and secondary station. The larger left bowl handles the heavy lifting: soaking a sheet pan, washing a stockpot, rinsing a head of lettuce. The smaller right bowl stays available for straining pasta, prepping vegetables, or keeping a colander in place while the main bowl is occupied. If your kitchen workflow tends to have one person doing multiple tasks at once, the asymmetric split keeps both bowls useful instead of doubling up on one function.

The white finish makes the configuration read cleanly on the countertop and keeps the visual weight of a two-bowl sink from feeling heavy in a bright kitchen.

Quartz Composite in White

The sink body is quartz composite, a dense material made from 80% quartz blended with acrylic resin. White is the finish here, and because the color runs through the composite body rather than sitting as a surface coating, minor scuffs and everyday wear do not expose a different color underneath. The non-porous surface resists staining and does not hold food residue the way a textured surface can, which makes routine cleaning straightforward. Both bowls share equal depth at 9 inches, so the material and performance are consistent across the full sink.

Where This Sink Fits Best

This sink is designed for a primary kitchen installation where the countertop is being fabricated new or replaced. It requires a solid countertop material, granite, quartz, or solid surface, to support an undermount bond, and it needs a 36-inch minimum base cabinet to clear the 32-inch outer width. It is not designed for drop-in or top-mount installation, and it should not be ordered as a replacement into an existing cutout built for a different sink. Plan it in at the countertop-fabrication stage for the cleanest result. The white finish coordinates with painted cabinetry, bright tile, and countertops in light neutral tones, and it also contrasts well with darker countertop materials where a high-contrast look is the goal.
