A Retrofit Farmhouse Sink Built for Existing Kitchens
The Karran QAR-740 brings the exposed-apron farmhouse look to kitchens that weren't originally built for it. This extra-large single-bowl quartz sink installs into a standard 36-inch wide sink base cabinet, replacing the false drawer fronts with a 6-1/2-inch Concrete apron — so the remodel gets the style without replacing the cabinetry.
Key Features
• Retrofit apron design fits a standard 36-inch sink base after removing false drawer fronts and cutting the face frame.
• Extra-large single bowl offers an uninterrupted basin well suited to washing large pots, sheet pans, and oversized cookware.
• Quartz composite construction combines 80% natural quartz crystals with 20% high-performance acrylic resin for highly scratch, stain, chip, and heat resistant performance.
• Concrete finish delivers a warm, textured neutral that pairs naturally with wood tones, matte hardware, and mixed-material countertops.
• 9-inch bowl depth keeps the working basin deep enough for full submersion of pots and baking dishes.
• No faucet deck means the faucet mounts through the countertop, keeping the sink's profile clean and uncluttered.
Where the Retrofit Advantage Makes the Difference
Most farmhouse sinks demand a purpose-built base cabinet — a significant cost and scope addition on a remodel. The QAR-740 is designed specifically for the opposite situation: the existing 36-inch sink base stays in place. The false drawer fronts come off, a rectangle is cut from the face frame flush to its top, and the sink's 6-1/2-inch apron slides into the opening with its sides engaging the face frame. Horizontal support strips set 3/8 inch below the cabinet top edge carry the sink's weight, and the rim finishes flush with the surrounding cabinet tops. This is still a real modification — the face frame is cut and support strips are added — but it avoids tearing out and replacing the entire cabinet run, which is the more disruptive and expensive path. Have the actual sink in hand before cutting; no cutout template is included.
Quartz Composite in a Kitchen Finish That Works
The Concrete colorway reads as a structured, muted grey-brown — grounded enough to anchor a natural wood kitchen, distinct enough to work against white or cream cabinetry without disappearing. Because the color runs through the quartz composite material rather than sitting on a surface coating, chips and minor abrasions don't expose a contrasting substrate. The quartz composite resists scratches, stains, chips, and heat through its material composition. Daily use — hot pans set in the basin, cutting board drag, mineral deposits from hard water — is what this material is built for. Faucet and soap dispenser mount through the countertop, not through the sink, so hardware placement stays flexible.
Right Fit for the Project and the Customer
This sink is the practical choice for kitchen remodelers who want the farmhouse aesthetic without the commitment of replacing cabinetry. Cabinet shops fabricating for renovation clients, contractors sourcing for kitchen refreshes, and homeowners planning a weekend-scale upgrade all land here for the same reason: the QAR-740 delivers an exposed apron front without requiring a custom-ordered farmhouse base. The extra-large single bowl configuration suits households that hand-wash, cooks who work with large equipment, and anyone who finds divided bowls more limiting than useful. For new construction or full cabinet replacements where a deep-apron 9-1/4-inch QA model fits the plan, that line covers the standard farmhouse install path.
Frequently Asked Questions
Does retrofit installation mean I don't need to modify the cabinet?
The face frame is still cut — retrofit means it fits a standard 36-inch sink base rather than a purpose-built farmhouse base. The false drawer fronts come off, a rectangle is cut from the top of the face frame, and support strips are added inside the cabinet walls to carry the sink. It is a real modification, just a smaller one than replacing the cabinet entirely.
Is a cutout template included?
No template ships with the QAR-740. Have the actual sink on hand before fabricating any cuts, and measure from the sink itself.
Where does the faucet mount on this sink?
The QAR-740 has no faucet deck, so the faucet, soap dispenser, or any other accessory mounts through the countertop. This gives more flexibility in faucet positioning but means the countertop needs to be drilled before install.
How does the Concrete finish hold up to staining?
The quartz composite material is highly stain resistant, and Concrete is a mid-tone that doesn't show water spots and mineral deposits the way a lighter white or bisque color does. For routine care, a mild non-abrasive cleanser is all that's needed.
What is the difference between the QAR and QA models?
QA models have a 9-1/4-inch apron and install into a farmhouse sink base cabinet built or modified for that depth. QAR models have a 6-1/2-inch apron and install into a standard 36-inch sink base. The bowl depth on both is 9 inches. Choose QAR when the existing cabinet is staying; choose QA when the cabinetry is new or purpose-built.
The Farmhouse Look, on the Remodel's Terms
The QAR-740 makes the exposed-apron kitchen achievable without rebuilding around it — an extra-large quartz basin, a Concrete finish that ages well, and an installation path that works with what's already there.
