Karran Quartz Retrofit Apron Sink For Standard Sink Base Cabinets
The Karran QAR-740 brings full farmhouse character to an existing kitchen by fitting the sink's 6-1/2 inch apron into a standard 36 inch sink base cabinet — no purpose-built cabinetry required. The extra-large single bowl and deep Black quartz composite construction deliver the look and working depth of a farmhouse build without the cost of replacing the cabinet.
Key Features
• Retrofit apron design installs into a standard 36 inch wide sink base after removing false drawer fronts and cutting the face frame to the apron opening.
• Extra-large single bowl provides an unobstructed interior for washing large pans, deep trays, and oversize cookware.
• 80% quartz, 20% acrylic resin construction delivers high resistance to scratches, stains, chips, and heat in daily kitchen use.
• Black quartz finish maintains a consistent, through-body color so minor surface marks do not expose a contrasting substrate.
• 9 inch bowl depth gives generous clearance for soaking, rinsing, and filling tall stockpots.
• No faucet deck on the sink body means the faucet and any accessories mount through the countertop rather than the sink.
Where the Retrofit Apron Advantage Matters Most
A remodel that keeps the existing cabinetry is where the QAR-740 earns its place. Rather than specifying a purpose-built farmhouse base, the installer removes the false drawer fronts from the standard sink base, cuts a rectangle from the face frame to the apron dimensions, and sets horizontal support strips 3/8 inch below the cabinet top edge. The sink's 6-1/2 inch apron slides about 1/2 inch into that opening and the result reads as a built-in farmhouse sink from every visible angle. For contractors refreshing kitchens on a defined scope, or homeowners updating a kitchen without gutting the cabinetry, this installation path saves significant time and cost. The QAR-740 does not come with a cutout template; the actual sink should be on hand before the countertop cut is made.
Quartz Composite in Black: Material and Durability
Quartz composite at 80% natural quartz and 20% acrylic resin performs differently from stainless or fireclay in ways that matter at the prep sink. The material is highly scratch resistant under normal cutting and scrubbing, highly stain resistant against common kitchen agents, and chip resistant at the rim and bowl corners where daily contact is heaviest. Heat resistance means the surface handles typical cooking and rinsing loads without damage, though the bowl is not a substitute for a trivet under sustained direct heat. The Black colorway runs through the body of the material, so the surface does not show a different color beneath if contact marks appear. Routine cleaning with non-abrasive cleansers keeps the finish looking consistent over time.
The Right Fit for This Sink
Cabinet shops and kitchen designers working on remodels will find the QAR-740 useful wherever the client wants an apron-front aesthetic but the project budget or scope does not support replacing the base cabinet. The 34 inch wide, extra-large single bowl suits households that prioritize open working space over a divided basin — a strong choice for cooks who regularly handle large pots, sheet pans, or colanders. Because the faucet mounts through the countertop and not the sink, there is flexibility in specifying faucet style without being constrained by pre-drilled hole placement. The Black finish coordinates well with matte hardware and dark countertop materials, making it a straightforward specification in modern and transitional kitchen schemes.
Frequently Asked Questions
Does this sink require a special farmhouse base cabinet?
No. The QAR-740 is designed specifically to retrofit into a standard 36 inch wide sink base. You remove the false drawer fronts, cut an opening in the face frame to the apron dimensions, and set the sink on horizontal support strips. A purpose-built farmhouse cabinet is not required.
Does the face frame still need to be cut for the retrofit installation?
Yes. Retrofit does not mean the cabinet goes in unchanged. The face frame opening is cut to fit the apron, and the false drawer fronts are removed. The shorter 6-1/2 inch apron (versus the 9-1/4 inch apron on QA standard farmhouse models) is what makes a standard base cabinet viable.
Is a cutout template included with the sink?
No cutout template is included. The actual sink should be present before the countertop is cut, so that measurements are taken from the physical unit.
Where does the faucet mount on this sink?
The QAR-740 has no faucet deck. The faucet and any soap dispenser or accessory mount through the countertop, giving you full control over hole placement and faucet style during the countertop fabrication.
What countertop materials work with this sink?
The QAR-740 installs in quartz, granite, and solid surface countertops using standard undermount methods. Confirm the installation approach with your countertop fabricator before cutting, as method and adhesive selection depend on the countertop material.
A Farmhouse Sink That Works Within Your Project Scope
The QAR-740 delivers the deep single-bowl capacity and exposed apron front of a true farmhouse sink without requiring a cabinet replacement — a practical specification for remodels where the goal is a fresh look, not a full gut.
