Two Bowls, One Footprint: A Large/Small Layout Built Into Quartz
The Karran QA-760 is a quartz composite undermount kitchen sink with an unequal large/small bowl configuration, spanning 34 by 21-1/4 by 9 inches. It installs beneath quartz, granite, and solid surface countertops and brings a dedicated small prep bowl to the same footprint as a full-size wash station, all in White.
Key Features
• Large/small bowl layout pairs a full-size wash basin with a smaller dedicated prep bowl in a single undermount unit.
• 80% quartz, 20% acrylic resin construction delivers high resistance to scratches, stains, chips, and heat in daily kitchen use.
• Undermount installation positions the sink below the countertop surface, keeping the counter edge clean and easy to wipe down.
• White finish offers a crisp, neutral look that pairs with a wide range of countertop colors and cabinet finishes.
• 9-inch bowl depth accommodates deep pots, sheet pans, and large cookware in the main basin.
Where the Split Bowl Earns Its Place
An unequal bowl layout solves a specific problem that a single basin or a true 50/50 split cannot: you need a large working space for washing and rinsing, and a separate, smaller space for food prep, draining pasta, or holding a colander without giving up half the sink to do it. The large bowl in the QA-760 handles the heavy workload, while the small bowl sits ready for the secondary task. Cabinet shops and designers who spec kitchen cabinetry know this configuration by name because clients request it regularly — it is the most practical bowl split for a household that hand-washes dishes and cooks from scratch. The 9-inch depth on the main bowl means full sheet pans and stockpots sit flat on the bottom rather than angling across a shallow basin.
Quartz Composite in a Working Kitchen
Quartz composite is the right material for a kitchen sink that sees daily contact with hot pots, acidic foods, and cutting boards slid across the counter into the bowl. At 80% natural quartz crystals bound in 20% acrylic resin, the material is highly resistant to scratches, stains, chips, and heat — the four failure modes that degrade a kitchen sink surface fastest. The White colorway runs through the material rather than sitting on the surface as a coat, so nicks and wear do not expose a contrasting base. Because the QA-760 undermounts beneath the countertop, no rim interrupts the counter surface — the edge of the stone or quartz top finishes cleanly at the bowl opening, and crumbs wipe straight in from the counter without a lip to catch them.
The Right Sink for This Project
This sink fits best in a kitchen renovation where the countertop is quartz, granite, or solid surface and the client wants an undermount installation with a dedicated prep zone alongside the main wash station. It suits cabinet shops building and installing complete kitchen packages, designers specifying a full sink and countertop combination, and homeowners replacing a single basin or a 50/50 split who want more workflow flexibility without moving to a workstation-style sink. Because the faucet mounts through the countertop rather than a sink deck, the QA-760 works in countertop layouts where the faucet position is set by the countertop fabricator. Note that a drain assembly is not included and should be ordered separately to complete the installation.
Is this an undermount-only sink, or can it be installed as a top mount?
The QA-760 is designed for undermount installation. The flat rim sits beneath the countertop surface and is not configured for a drop-in or self-rimming application.
What countertop materials work with this sink?
The QA-760 undermounts in quartz, granite, and solid surface countertops using the installation method appropriate for the material. It is not a seamless Q Series model, so it does not use the laminate/solid surface bevel-bit seamless method.
Which bowl is the large bowl — left or right?
The SAP description indicates a left-hand large bowl and right-hand small bowl orientation. Confirm orientation from the model documentation and spec sheet before cutting the countertop.
Does the sink come with a drain, grid, or other accessories?
This SKU is a bare sink. A drain assembly, bottom grid, and any additional accessories are sold separately. Check Karran's model-specific fit tables to match the correct grid and strainer to each bowl.
Is the white quartz composite easy to keep clean?
Quartz composite is non-porous and resistant to staining, so most residue wipes away with a soft cloth and mild detergent. Avoid abrasive pads, which can dull the surface over time.
A Practical Sink That Works as Hard as the Kitchen Around It
The QA-760 brings together the durability of quartz composite, a versatile large/small bowl split, and a clean undermount profile — giving fabricators, designers, and homeowners a sink that pulls its weight from the first install through years of daily use.
