An Undermount Workstation Sink Built for Balanced Prep and Cleanup
The Karran QUWS-880-GR brings a full prep station below your countertop line, pairing equal-depth wash and rinse bowls with an integrated ledge system designed to hold cutting boards, colanders, and drying accessories directly over the bowls. Made from quartz composite and finished in Gray, it installs as a standard undermount in solid surface, stone, and quartz countertops.
Key Features
• Quartz composite construction combines 80% natural quartz with 20% acrylic resin for a bowl that resists scratches, stains, chips, and heat.
• Integrated workstation ledge runs the perimeter of the sink rim, allowing cutting boards, colanders, and racks to slide directly over the bowls.
• Equal 50/50 bowl configuration gives both sides identical depth and width, supporting a dedicated wash station and a separate rinse or prep zone at the same time.
• Undermount installation places the rim beneath the countertop for a clean, wipe-down counter edge and no visible rim break.
• Kit includes key accessories so the prep station is ready to use from the start, with no sourcing accessories separately.
• Gray finish is a neutral quartz color that reads naturally alongside white, concrete, and wood-tone cabinetry.
Two Bowls, One Continuous Prep Zone
Equal-bowl sinks earn their place in kitchens where tasks routinely run in parallel. Soaking on one side while prepping vegetables on the other, or rinsing produce while a pot holds on the wash side — neither bowl loses working depth to an asymmetric split. The 9-inch bowl depth handles stockpots and sheet pans without forcing awkward tilting. Because the ledge spans the full width of the sink opening, accessories slide from one side to the other so you can follow the workflow without lifting anything off the sink. The cutting board parks over the prep side; a quick slide and it's over the bowl that needs it. The colander and drying rack travel the same track.
Quartz Composite in a Gray That Holds Up Daily
Gray quartz composite reads darker than White and lighter than Black, landing close to a mid-tone concrete that stays visually clean even on busy days. Because the color runs through the full quartz composite material rather than sitting as a surface coat, small marks from normal use don't break through to a contrasting color beneath. The 80% quartz content drives the material's resistance to scratches, chips, and heat — the category rule is resistance, not immunity, which means the bowl handles a hot pan set down momentarily but should not be used as a trivet for sustained high heat. The non-porous surface does not harbor bacteria or absorb odors between cleanings. Routine care is soap and water; harsh abrasive scrubbers are not recommended because they dull the surface over time.
Right for Renovation Projects and Working Kitchens Alike
Cabinet shops and kitchen designers specifying sinks for quartz, granite, or solid surface countertops will find the QUWS-880-GR straightforward to work into a standard 36-inch sink base layout. The undermount profile means the stone or solid surface fabricator finishes the cutout edge as part of the countertop work — no visible rim, no caulk bead on top of the counter. Homeowners rebuilding a kitchen around better prep habits will appreciate getting the ledge system, cutting board, colander, and drying rack in the kit rather than assembling a workstation piecemeal. The 32-1/2 by 19-1/4 inch footprint fits where most standard double-bowl sinks land, which simplifies the transition from a conventional undermount to a workstation setup.
Does this sink require any special countertop material to undermount correctly?
Standard undermount installation works with solid surface, stone, and quartz countertops. The fabricator attaches the sink from below using clips and adhesive per the countertop manufacturer's method. This is not a seamless-series sink, so it does not require the seamless laminate or solid surface fabrication process used for Karran's Q Series.
What accessories ship in the kit?
The QUWS-880-GR is a kit SKU that includes a grid, basket strainer, cutting board, colander, drying rack, and Luster Pro oil. Confirm the complete list against the packing slip on arrival, as accessory sets are model-specific and may be updated by the manufacturer.
Is a drain or faucet included?
A basket strainer is included in the kit. A faucet is not included and mounts through the countertop rather than through a faucet deck on the sink. The faucet and any additional drain hardware should be sourced separately.
How does the equal bowl layout compare to a large/small split?
Both bowls measure the same interior dimensions, so neither side takes working depth away from the other. A large/small split trades one generous bowl for a shallower utility bowl; the equal layout is better when two full-depth stations are regularly in use at the same time.
A Workstation Sink That Earns Its Footprint Every Day
The QUWS-880-GR turns a standard 32-1/2 inch undermount opening into a working prep station without asking for more counter space in return. Two equal bowls, a ledge that keeps accessories where they're needed, and a quartz composite surface built to handle daily use — it's a practical upgrade for any kitchen where the sink does real work.
