Black Quartz Undermount Sink for a Bold, High-Capacity Kitchen
The Karran QA-740 in Black is an extra-large, single-bowl undermount kitchen sink crafted from 80% natural quartz and 20% acrylic resin. Its generous footprint and deep 9-inch basin make it a natural fit for busy kitchens that handle heavy loads, large cookware, and uninterrupted prep sessions.
Key Features
• Dramatic Black finish brings a strong visual contrast to light stone, white quartz, or concrete countertops.
• Extra-large single bowl provides an unobstructed workspace for sheet pans, stockpots, and oversized cutting boards.
• Quartz composite construction (80% quartz / 20% acrylic resin) delivers high resistance to scratches, stains, chips, and heat under daily kitchen use.
• Undermount installation keeps the countertop edge clean and uninterrupted, with no rim collecting water or debris.
• 9-inch bowl depth contains splatter and accommodates tall items that a shallower bowl would not.
Built for Kitchens That Work Hard
A single uninterrupted basin this size handles tasks that a divided bowl simply cannot. Sheet pans lay flat. A stockpot fills without angling under the faucet. Soaking large cutting boards, rinsing bulky produce, and cleaning oversized bakeware all become straightforward instead of awkward. The 9-inch depth keeps splatter contained even when the bowl is loaded. For kitchens where the sink is a working tool rather than a background fixture, the extra capacity changes how the space functions day to day.
Quartz Composite in Black: Material and Finish
Quartz composite at this ratio is highly scratch-, stain-, chip-, and heat-resistant, with the surface holding up to the routine punishment of knife rinses, cast iron, and hot cookware. The Black color runs through the material rather than sitting only at the surface, so nicks and chips do not expose a contrasting base underneath. Matte black quartz also hides water spots and surface residue better than a polished stainless finish, reducing the frequency of wipe-downs needed to keep the sink looking clean. Because it is non-metallic, the bowl does not ring with the acoustic report that thin stainless sinks produce when a pot lands in it.
The Right Kitchen for This Sink
This sink suits kitchens where the countertop is quartz, granite, or solid surface and the designer or fabricator is handling a professional undermount installation. It works equally well in a high-use home kitchen where the owners hand-wash large items, a luxury remodel where the dark sink anchors the design scheme, or a custom cabinet shop's display kitchen where material durability is part of the story being told. Designers specifying dark hardware throughout the kitchen will find that Black quartz coordinates with matte black faucets and pulls without the finish-matching complexity that comes from mixing metals. The sink's size also makes it appropriate for open-plan kitchens where the sink is visible from the living area and needs to read as a design element, not just a utility fixture.
Frequently Asked Questions
Is this sink suitable for a laminate countertop?
The QA-740 is an undermount sink designed for countertop materials such as quartz, granite, and solid surface that support undermount installation. Laminate is generally not recommended for undermount sinks because the substrate around the cutout is exposed to moisture. If your project involves a laminate top, the Q Series seamless line is the appropriate Karran option for that countertop material.
Does the sink ship with clips, a template, or a drain?
Per Karran's standard documentation for this series, mounting clips and a paper template are not included. A drain assembly is also not included and is sold separately. Confirm your fabricator's preferred clip and drain system before ordering.
How does black quartz compare to black stainless for maintenance?
Quartz composite is non-metallic and non-porous, so it does not show fingerprints the way coated black stainless does, and there is no finish layer to scratch through to a base metal. Routine cleaning with a mild, non-abrasive cleaner keeps it looking consistent over time.
What faucet configuration does this sink require?
Because this is an undermount sink without a faucet deck, the faucet and any accessories such as a soap dispenser mount through drillings in the countertop itself. The number and placement of those holes are determined by the fabricator during countertop prep.
A Sink That Anchors the Kitchen
The QA-740 in Black delivers the capacity, durability, and visual weight to serve as the centerpiece of a serious kitchen, finished in a color that holds its look and works across a wide range of design directions.
