The Karran 31-3/8" Undermount Large Single Bowl Quartz Composite Workstation Kitchen Sink Kit in White is designed for installation in granite, quartz, and solid surface countertops. Made from an 80% quartz and granite composite blended with 20% acrylic resin, it brings the look and feel of natural stone together with a 1/2" positive reveal ledge built for workstation accessories. The refined matte surface is heat resistant up to 535°F, and the dense composite naturally absorbs vibration to quiet running water and dishwashing noise. The kit includes a flush-fit bamboo cutting board, a roll-up drying rack, and a white basket strainer, so this white quartz workstation sink is ready to prep, wash, and dry from the day it is installed.

Workstation Ledge Design: Prep, Rinse, and Dry in One Place

The 1/2" positive reveal along the rim of this white undermount quartz workstation sink creates a dedicated ledge for accessories, so the included bamboo cutting board sits flush and level with the countertop for a more integrated look and effortless cutting. That flush fit keeps the board stable during use rather than teetering on an uneven edge, and it extends the usable prep surface directly over the bowl. The 29" x 16-3/8" x 9" bowl has no center divide, giving you one large, open basin for washing oversized pots, sheet pans, and roasting trays without tilting, stacking, or splashback. Rounded corners throughout the bowl wipe clean easily, with no tight seams for food residue to collect.

An undermount installation lets the countertop run uninterrupted to the edge of the cutout, with no rim or lip resting on top of the material, so crumbs and spills sweep straight into the bowl. The reversible offset drain lets you choose the drain location at installation, moving the plumbing to whichever side of the cabinet suits your layout and leaving more usable storage space below the sink. The included roll-up drying rack supports up to 40 lbs, is dishwasher safe, and rolls up for compact storage when the counter needs the room. A sink-matched basket strainer catches food debris to help keep the drain clear, and its color coordinates with the sink for a finished look.

Matte White: A Clean, Enduring Finish for Any Kitchen Style

Clean and bright, white is a color that goes with almost anything. It suits painted cabinetry tones ranging from bright white and soft grey to deep navy and sage. It works well across the full range of countertop materials, whether cool-toned marble, warm quartz, or honed granite. Its matte, smooth finish absorbs and diffuses light, softening the starkness often associated with this color. UV stabilization prevents the color from changing or yellowing, even after years of heavy use.

Quartz Composite Performance: Durable, Sound-Absorbent, and Low-Maintenance

Built from an 80% quartz and granite composite blended with 20% acrylic resin, this white quartz kitchen sink delivers a dense, non-porous surface that resists staining, scratching, abrasion, and impact through years of demanding use. The color is integrated into the material rather than painted on, so it stays consistent across the entire basin. Rated heat resistant up to 535°F, the surface handles hot cookware set directly in the bowl without damage. Sealing is not required, and routine cleaning with mild soap and water keeps the matte finish in excellent condition. The same dense composite naturally absorbs vibration and sound, dampening the noise of running water and cookware for a quieter kitchen.

Specifications and What’s Included

This white quartz workstation sink measures 31-3/8" x 18-7/8" x 9-1/2" overall, with a 29" x 16-3/8" x 9" bowl and a 3-3/4" drain, and it requires a minimum 36" cabinet. A cutout template and digital DXF file are included so the sink cutout is specific to this workstation installation, along with mounting clips for a secure undermount fit. The kit includes a white basket strainer, a bamboo cutting board, and a roll-up drying rack, giving you everything needed to use the ledge on day one.
