A Retrofit Farmhouse Workstation Sink Built for Standard Cabinets
The Karran QARWS-740-CN brings the farmhouse apron-front look and a fully integrated workstation ledge to kitchens that don't have a purpose-built farmhouse base. Made from Karran's 80% quartz, 20% acrylic resin composite in Concrete, this large single-bowl sink retrofits into a standard 36-inch wide sink base, making it the practical path to an apron-front kitchen without a full cabinet replacement.
Key Features
• Retrofit apron-front design: The 6-1/2-inch tall apron installs into a standard 36-inch sink base after removing the false drawer fronts and cutting the face frame, no farmhouse-specific cabinet needed.
• Integrated workstation ledge: A built-in ledge around the bowl perimeter holds compatible cutting boards, colanders, and drying racks directly over the basin.
• 80% quartz composite construction: Highly scratch-, stain-, chip-, and heat-resistant material that holds up through daily prep and cleanup.
• Large single-bowl configuration: One uninterrupted basin handles oversize cookware, sheet pans, and full workstation workflows without a center divider.
• Concrete quartz finish: A muted, warm gray tone that works with both modern and transitional kitchen palettes.
• No faucet deck: Faucet and accessories mount through the countertop, keeping the sink surface uninterrupted.
Workstation Capability on an Apron-Front Platform
The QARWS-740-CN is built around two things that rarely appear together: the exposed farmhouse apron front and the functional workstation ledge. The ledge runs the perimeter of the bowl and accepts Karran-compatible accessories — cutting boards, colanders, drying racks — so prep, wash, and drain tasks all happen in one contained zone. The large single-bowl layout gives those accessories room to work without a divider interrupting the space. Because the faucet mounts through the countertop rather than a sink deck, the full bowl width stays available for whatever is on the ledge.
This is a QARWS-series sink, which means the workstation capability is paired with a retrofit apron design rather than a standard farmhouse installation. The apron is shorter than the QA-series (6-1/2 inches versus 9-1/4 inches), sized specifically to slide into a standard sink base opening after the face frame is prepared. Workstation accessories are sold separately; confirm compatibility by model before ordering.
Quartz Composite in Concrete: Material and Finish
Karran's quartz composite is 80% natural quartz crystals bound in 20% high-performance acrylic resin. The result is a dense, non-metallic bowl that resists the scratches, stains, chips, and heat exposure of an active kitchen. The Concrete color is a soft, textured gray that reads as neutral across a wide range of countertop materials and cabinet finishes. The matte composite surface doesn't show water spots or minor marks the way polished stone does, which matters on a workstation sink that sees constant use. Quartz composite is an indoor material suited to controlled-environment kitchens.
Who This Sink Is For
This sink fits three specific situations well. First, the remodeling homeowner who wants an apron-front look but is keeping the existing standard sink base — the QAR retrofit path makes that possible without a full cabinet replacement. Second, the kitchen designer specifying an integrated prep zone with farmhouse character, particularly in projects where countertop space is limited and the workstation ledge extends usable work surface over the bowl. Third, the cabinet shop or contractor managing a kitchen renovation who needs a single product to satisfy both the aesthetic brief (exposed apron, Concrete finish) and the functional brief (workstation prep station) in one SKU. The Concrete finish works across quartz, stone, wood, and painted cabinet environments.
What cabinet modifications does the QARWS retrofit install actually require?
The false drawer fronts are removed, and a rectangle is cut from the top of the face frame flush with its top rail. The sink then rests on support strips set 3/8 inch below the cabinet's top edge, with the side aprons sliding about 1/2 inch into the face-frame opening. The face frame is cut — this is not a drop-in swap — but no farmhouse-specific cabinet is needed.
Is a cutout template included with this sink?
No cutout template is included. The actual sink should be on hand before any cabinet or countertop cutting begins. Karran provides downloadable DXF files for CNC cutouts where applicable.
What workstation accessories are included in the box?
Workstation accessories for the QARWS-740 are sold separately. The source data for this SKU does not resolve a specific included accessory pack, so confirm the exact kit contents at time of order and purchase compatible cutting boards, colanders, and drying racks as separate line items.
Where does the faucet mount on this sink?
The QARWS-740-CN has no integrated faucet deck, so the faucet mounts through the countertop. Plan your countertop drilling to match your faucet's hole configuration before fabrication.
How does the Concrete finish compare to Karran's other quartz colors?
Concrete is a mid-tone warm gray, distinct from Karran's Grey (cooler) and Brown (warmer). It pairs well with white, wood-tone, and charcoal cabinets and reads as a neutral against most stone countertop patterns. The matte composite surface is consistent throughout, so minor scratches don't create a color contrast.
Farmhouse Character, Standard-Cabinet Fit, Ready-to-Outfit Basin
The QARWS-740-CN delivers the apron-front look, workstation function, and quartz durability in a package that works with the cabinet run you already have — so the renovation moves forward without the full base cabinet overhaul.
