A Concrete-Finish Farmhouse Sink Built for Workstation Performance
The Karran QAWS-740 brings together an exposed-apron farmhouse profile and a full-perimeter workstation ledge in a single quartz composite basin finished in Concrete. Sized at 34 by 21-1/4 by 9 inches, it installs as a standard deep-apron farmhouse sink into a purpose-built or modified farmhouse sink base cabinet, then puts the ledge and its compatible accessories to work above the bowl.
Key Features
• Quartz composite construction blends 80% natural quartz crystals with 20% acrylic resin for a basin that resists scratches, stains, chips, and heat in day-to-day kitchen use.
• Exposed 9-1/4 inch apron delivers the full-depth farmhouse look when installed into a farmhouse sink base cabinet with the face frame cut to apron dimensions.
• Full-perimeter workstation ledge accepts sliding cutting boards, colanders, and drying racks, keeping prep tools over the bowl and counter space clear.
• Concrete finish pairs naturally with raw wood, matte hardware, and industrial-leaning cabinet designs without the upkeep of a lighter color.
• Large single-bowl configuration provides an uninterrupted basin suited to large cookware, sheet pans, and high-volume prep.
• No faucet deck on the sink keeps the basin footprint clean; the faucet and any accessories mount through the countertop.
Workstation Ledge Meets Farmhouse Installation
The QAWS series is built for kitchens where workflow matters as much as aesthetics. The perimeter ledge runs the full interior width of the bowl opening, so a sliding cutting board or colander stays centered over the basin and drains directly into it. That setup is particularly useful in high-use kitchens where prep, washing, and draining happen in the same zone without spreading across the counter. Because the bowl is a single large basin with no divider, there is nothing to work around when moving tools from one side to the other or fitting a large roasting pan flat on the bottom.
Installation follows the standard QA farmhouse path: the sink rests on level support strips screwed into the cabinet side walls, set so the rim sits flush with the cabinet tops on either side. The face frame of the farmhouse sink base is cut to the apron dimensions before the sink is set. Karran requires the actual sink to be on hand before any cutting begins. No cutout template is included.
Concrete Quartz in a Working Kitchen
Concrete is one of Karran's deeper, cooler quartz colors and reads as a warm grey-brown in most lighting conditions. On a workstation sink that sees daily cutting board and colander traffic, the finish holds up visually — minor scuffs and residue are less visible against a mid-tone composite than on a white or light grey basin. The quartz composite material itself is non-porous, so it does not harbor odors or bacteria from food prep, and it does not require sealing. Heat resistance is real but has limits; the manufacturer describes it as heat resistant rather than heat proof, so placing a cast-iron pan directly from the stovetop is not recommended.
Who This Sink Is Built For
This sink suits kitchen remodels and new builds where the designer or homeowner has committed to a farmhouse aesthetic and wants the prep functionality of a workstation built in rather than added separately. Cabinet shops specifying a complete kitchen package can pair the QAWS-740-CN with compatible workstation accessories and a countertop-mounted faucet for a cohesive spec. Contractors doing full kitchen renovations will find the Concrete finish coordinates with a wide range of cabinet stains, painted finishes, and quartz countertop options without demanding an exact color match. The large single bowl is also the right call for households that cook at volume or regularly handle large pots and pans that a divided sink cannot accommodate.
What cabinet does the QAWS-740 require?
The sink uses a standard QA farmhouse installation, which means a purpose-built farmhouse sink base cabinet — typically 36 inches wide — with the face frame cut to fit the 9-1/4 inch tall apron. This is not a retrofit-style sink and does not drop into a standard base without cabinet modification.
Is a cutout template included?
No template is included. Karran specifies that the actual sink must be present before fabrication begins. DXF files for CNC cutouts are available for download separately.
What accessories work with the workstation ledge?
The QAWS series ledge is designed for Karran's compatible sliding accessories including cutting boards, colanders, and drying racks. Confirm accessory model compatibility against the specific QAWS-740 fit table, as accessory dimensions are matched to the bowl size.
Does the sink include a drain or grid?
Inclusion of basket strainers, bottom grids, and Luster Pro oil depends on the pack suffix ordered. Confirm the contents of the specific SKU being purchased. The drain assembly is not part of the base sink.
Where does the faucet mount?
The QAWS-740 has no integrated faucet deck. The faucet, soap dispenser, and any other fixtures mount through the countertop, keeping the sink basin uncluttered.
One Sink, Two Capabilities Built In
The QAWS-740 in Concrete brings farmhouse character and workstation utility into a single quartz basin, so the kitchen does not have to trade one for the other. The apron front defines the aesthetic, and the ledge puts that basin to work every time it is used.
