White Quartz Undermount Sink for a Clean, Unbroken Counter

This Karran quartz undermount kitchen sink pairs a larger prep bowl with a smaller rinsing bowl in a crisp white finish, mounting beneath the countertop so the counter surface runs flush to the basin edge without an exposed rim.

Key Features

• 60/40 double bowl gives a generous large bowl alongside a compact secondary bowl for flexible task separation.
• Quartz composite construction blends natural quartz with acrylic resin for a dense, hard-wearing basin.
• White finish with a consistent color through the material, not a surface coating.
• Undermount installation compatible with granite, quartz, and solid surface countertops.
• IAPMO certified for code-compliant residential and light commercial installs.
• Requires a minimum 36-inch cabinet to support the 32-inch side-to-side footprint.

Two Bowls, Two Jobs

A 60/40 split means the larger bowl handles the heavy lifting: soaking pots, washing large cutting boards, or working through a full stack of dishes. The smaller bowl stays available for rinsing produce, draining pasta, or keeping a basin of clean water separate from the wash side. The two bowls make the sink genuinely more functional than an equal split, where neither bowl is ever quite big enough for the larger task.

Both bowls share a 9-inch inside depth, so there is room to work without water splashing out, and the large bowl measures 17-1/4 inches long by 15-3/4 inches wide to accommodate most cookware.

White Quartz That Holds Its Look

The white finish here is part of the quartz composite body rather than a painted or coated surface. The material is dense and non-porous, which means it does not readily absorb food dyes or retain staining the way a porous surface can. White sinks show water spots and minor marks more readily than darker colors, but because the color goes through the material, surface wear does not expose a different color underneath. The finish stays consistent with daily kitchen use.

The 3-1/2 inch drain opening accepts standard waste fittings, and the sink carries IAPMO certification, meeting the code requirements most local inspectors look for in kitchen sink installations.

Where This Sink Fits Best

This is a strong choice for a primary kitchen sink in any renovation or new build where white cabinetry, white countertops, or a light overall palette is the design direction. The undermount profile works in granite, quartz, and solid surface countertops, making it a practical fit for the most common countertop materials in that aesthetic. Because it is undermount only, it belongs in a new countertop rather than an existing one with a pre-cut drop-in opening. The 36-inch minimum cabinet requirement is a firm fitment spec, so confirm the base cabinet width before finalizing the countertop cutout.

Designers specifying a bright, cohesive kitchen and contractors installing a full kitchen package will both find this sink easy to fit into a white or light-toned plan. The IAPMO certification simplifies the inspection process on permitted work.
