A Double-Bowl Farmhouse Sink Built for Dark, Design-Forward Kitchens
The Karran QA-750 in Black is a standard farmhouse apron-front kitchen sink made from quartz composite, offering two equally deep bowls behind a bold exposed apron. It is designed for new construction and full remodels where the cabinetry is built or modified specifically to carry an apron-front sink.
Key Features
• Black quartz composite construction uses 80% natural quartz and 20% acrylic resin for a hard, dense surface that stands up to daily kitchen use.
• Exposed apron front sits proud of the cabinet face, delivering the farmhouse silhouette from the moment the cabinets are installed.
• Double-bowl configuration splits the sink into two working basins, supporting a wash-and-rinse workflow or dedicated prep and clean-up sides.
• 9-inch bowl depth gives both basins substantial clearance for tall pots and stacked cookware.
• Highly scratch, stain, chip, and heat resistant surface holds its finish under the routine impact and temperature swings of an active kitchen.
• Standard farmhouse (QA-style) installation mounts into a farmhouse sink base cabinet on level support strips, with the sink's weight carried by the cabinet structure.
Where the Black Apron Does Its Best Work
This sink earns its place in kitchens where finish coordination runs the full room: matte black cabinet hardware, dark stone countertops, or two-tone cabinetry where a white sink would break the palette. The double-bowl layout suits kitchens that handle volume — meal prep on one side, cleanup on the other — without sacrificing the clean, furniture-like front a farmhouse design delivers. It is equally at home in a high-use family kitchen and in a designer showroom spec where the sink is part of the visual story. Because this is a standard QA installation, it fits best in new builds and full remodels where the sink base can be purpose-built or correctly modified before the countertop goes in.
Quartz Composite in Matte Black
Quartz composite is one of the more demanding sink materials to match in a dark finish, and Karran's Black holds its color without the gloss that shows every water spot. The 80% quartz content gives the bowl walls and floor a stone-like density — there is no flex underfoot when the basin fills — while the acrylic resin binder allows the material to be molded into the full apron profile. The surface resists scratches, stains, chips, and heat well enough for everyday kitchen demands, though the manufacturer's care guidance applies: prolonged direct heat and abrasive cleaners shorten any quartz sink's finish life. No template is included with this sink; the actual sink must be on-site before the cabinetmaker fabricates the face frame and support system.
Who This Sink Is For
Cabinet shops building farmhouse-style kitchens will find this sink a straightforward spec: standard QA dimensions, documented installation method, and a finish that travels well across both modern and transitional kitchen styles. Designers specifying for clients who want a dark, cohesive kitchen palette will appreciate that Black quartz reads as a deliberate material choice rather than a neutral default. Contractors and homeowners planning a full kitchen remodel — where the sink base can be built to the apron — get a durable, design-forward fixture that will outlast trends. This sink is for indoor kitchen use only.
Frequently Asked Questions
Does this sink work as a retrofit into an existing standard sink base?
No. This is a QA-series standard farmhouse sink with a 9-1/4 inch tall apron, and it requires a farmhouse sink base cabinet — not a standard base with the false drawer fronts removed. If the existing cabinetry is a standard 36-inch sink base, the Karran QAR retrofit series (6-1/2 inch apron) is the correct option for that application.
How is the sink supported in the cabinet?
The sink rests on level horizontal support strips screwed into the cabinet side walls, with vertical supports beneath for additional strength. The countertop does not carry the sink's weight. Karran recommends having the actual sink on-site before the cabinetmaker cuts the face frame and installs the support system.
Are the two bowls the same size?
Yes. The QA-750 is a double-bowl configuration with equal basins. If an unequal large-and-small bowl layout is needed, a different model within the QA line serves that configuration.
Is a drain or basket strainer included?
No drain assembly or basket strainers are included with this sink. Compatible strainers and Karran-matched accessories are sold separately and should be confirmed and ordered alongside the sink.
Will the Black finish match other Karran accessories?
Karran offers grids, strainers, and other accessories in finishes designed to coordinate with their sink colors. Confirm the exact accessory model and finish against the QA-750 BL before ordering, as accessory fit is model-specific.
A Farmhouse Sink That Anchors the Kitchen Design
The QA-750 in Black delivers the farmhouse look with the material durability and bowl capacity a working kitchen actually needs — a sink that reads as a design decision from across the room and performs as a workhorse once the water runs.
