A Clean White Quartz Undermount Sink for Modern Kitchen Builds

The Karran QU-670-WH is a single-bowl quartz undermount kitchen sink in White, sized to fit a 36-inch base cabinet and designed to mount beneath granite, quartz, or solid surface countertops.

Key Features

• Single bowl design with a 29-inch interior length and 9-inch depth for a generous, unobstructed workspace.
• White quartz composite material built from a quartz-and-resin body with a consistent color throughout.
• Undermount installation into granite, quartz, or solid surface countertops for a seamless countertop edge.
• Fits a 36-inch minimum cabinet width with an overall footprint of 31-3/4 inches wide by 19-3/4 inches front to back.
• 3-1/2 inch drain opening sized for a standard waste fitting or basket strainer.
• cUPC and IAPMO certified for code compliance in residential and commercial kitchen installations.

One Open Bowl for the Way a Kitchen Works

A single bowl gives you an uninterrupted basin, which makes it easier to wash large pans, sheet trays, and cutting boards without working around a center divide. At 29 inches long and 9 inches deep, the interior handles a full cooking cleanup without crowding. The white finish keeps the basin bright and easy to read at a glance, so you can see what needs attention without leaning in. Because it undermounts, the countertop surface runs cleanly to the bowl edge with no rim collecting water or debris along the joint.

Quartz Composite in White

White in a quartz sink is not a surface coating applied over another material. The color runs through the quartz composite body, so chips or surface wear do not expose a contrasting underlayer. Quartz composite combines crushed quartz with a resin binder to produce a dense, non-porous basin that resists staining and keeps food residue from bonding to the surface. White is a practical choice in kitchens with light cabinetry, marble-look countertops, or any palette that benefits from a clean, neutral basin that does not draw attention away from the surrounding finishes.

Where This Sink Fits

This is the right sink for a new kitchen build or a full remodel where the countertop is being fabricated from scratch. Because undermount installation requires support from the countertop material above, it works with granite, quartz, and solid surface only. Laminate and tile countertops are not appropriate here. It needs a 36-inch base cabinet and is not ADA compliant, so it suits standard residential height installations rather than accessibility-focused builds. Designers specifying a clean, all-white kitchen and contractors setting a remodel kitchen with a fresh countertop will find this sink straightforward to integrate. The cUPC and IAPMO certifications satisfy residential and light commercial code requirements in most jurisdictions.
