A Double-Bowl Farmhouse Sink Built for Working Kitchens
The Karran QA-750 is a quartz composite apron-front kitchen sink with two equal bowls, sized at 34 by 21-1/4 by 9 inches overall and finished in White. It mounts underneath the countertop with a 9-1/4 inch exposed apron at the front, installing into a purpose-built or modified farmhouse sink base cabinet. The quartz composite construction — 80% natural quartz crystals bound in 20% acrylic resin — delivers the durability and visual weight that working kitchens and high-use renovation projects demand.
Key Features
• Two equal bowls support a dedicated wash-and-rinse workflow without competition for sink space.
• 80% quartz / 20% acrylic resin composite is highly resistant to scratches, stains, chips, and heat from daily kitchen use.
• 9-1/4 inch exposed apron presents the full farmhouse profile across the cabinet face, a standard QA-style installation.
• 9-inch bowl depth handles tall pots, full sheet pans, and other oversized cookware on either side.
• White finish works cleanly against both painted and natural cabinet lines and coordinates with a wide range of countertop materials.
• Undermount design with no faucet deck keeps the countertop surface continuous, so the faucet mounts through the counter rather than the sink.
Two Bowls, One Continuous Workflow
Splitting the basin into two equal sides gives this sink its practical edge. One bowl holds the wash, the other holds the rinse — or one side preps vegetables while the other holds a colander — without the two tasks interfering. That separation matters in kitchens where more than one person works at the same time, and it makes cleanup faster when the meal is done. The 9-inch depth on both bowls means neither side sacrifices capacity, so large stockpots and roasting pans fit just as easily on the prep side as on the wash side. Because the faucet mounts through the countertop rather than a sink deck, the counter surface stays clean and continuous from backsplash to bowl rim.
Quartz Composite in White: Material and Finish
Quartz composite is not a surface coating — it runs through the entire sink body. The 80% natural quartz content gives the material its hardness and its resistance to the scratches and chips that accumulate in a busy kitchen. The 20% acrylic resin binds the quartz tightly and provides the heat and stain resistance that makes the White finish hold up over years of use. White quartz reads warmer than stainless and stays brighter than grey or concrete finishes, making it a natural fit for kitchens with white or light-toned cabinetry and for Shaker-style designs where clean lines carry the look. Cleaning is straightforward: the non-porous surface does not harbor bacteria or absorb odors the way porous materials can.
Who This Sink Fits Best
This sink suits new construction and full kitchen remodels where the cabinetry is being built or modified specifically for the apron-front style. A standard QA installation uses a 36-inch farmhouse sink base cabinet, with the face frame cut to match the 9-1/4 inch apron height and 34-inch apron width. The sink rests on level support strips screwed into the cabinet side walls — it does not hang from the countertop — so the support system is built before the counter goes in. Cabinet shops ordering for a full project should have the actual sink on hand before fabricating the cabinet face; Karran does not include a cutout template with this model. For renovations that keep the existing standard sink base, the QAR retrofit line is the right path. This QA-750 is the choice when the job starts from scratch or the cabinet is purpose-built.
Is this a standard QA farmhouse installation or a retrofit?
This is a standard QA-style installation. It requires a farmhouse sink base cabinet — not a standard sink base — with the face frame cut to the apron dimensions. The QAR line handles retrofit installations into existing standard cabinets.
Does a drain, grid, or faucet come with this sink?
No. The QA-750 ships as the sink only. Basket strainers, bottom grids, and a faucet are all ordered separately. If you need a bundled package, look for the -PK1 configuration, which adds basket strainers, bottom grids, and Luster Pro oil.
Where does the faucet mount on this sink?
There is no faucet deck on this model. The faucet mounts through the countertop. Plan faucet hole placement in the countertop before fabrication is complete.
What countertop materials work with this sink?
As an undermount model, the QA-750 is compatible with solid surface, stone, and quartz countertops that support standard undermount installation. It is not a seamless-series sink and does not use the seamless laminate installation method that Karran's Q Series employs.
Do I need the actual sink before cutting the cabinet?
Yes. Karran specifies that the cabinetmaker should have the actual sink present before fabricating the cabinet face. No cutout template is included with this model, so dimensions must be taken from the sink itself.
Built for the Job from Day One
The QA-750 in White brings the farmhouse profile, the working depth, and the quartz durability together in a double-bowl format that holds up through years of daily use — and looks the part from the moment it goes in.
