Black Quartz Top Mount Sink for a Bold, Low-Maintenance Kitchen
The Karran QT-671 is a quartz composite top mount kitchen sink in Black, sized at 25 by 22 by 9 inches to fit a standard 30-inch sink base cabinet. Its drop-in installation drops straight into an existing cutout in any countertop material, making it a strong choice for remodels, replacements, and new builds alike.
Key Features
• Top mount installation drops into any countertop material, covering the cut edge with the sink's perimeter rim.
• Matte Black quartz composite construction holds a bold, consistent color throughout the 80% quartz body rather than just at the surface.
• Single bowl configuration gives uninterrupted interior space for washing large pans, sheet trays, and oversize items.
• Highly scratch, stain, chip, and heat resistant quartz composite material handles the demands of a daily-use kitchen station.
• 9-inch bowl depth provides generous working capacity and keeps splashing contained.
Why the Drop-In Format Works Here
Top mount installation is the most forgiving path for a kitchen sink replacement. The rim seats directly on the countertop and clips secure from beneath, so there is no need to finish a countertop edge or modify the substrate underneath. For a contractor retrofitting an existing laminate counter, a kitchen designer updating a tile or butcher block surface, or a homeowner swapping out an old drop-in, the QT-671 fits without demanding changes to what is already there. The Black finish reads the same on day one as it does after years of use, because the color runs through the quartz composite body rather than sitting as a surface coating.
Quartz Composite Built for Working Kitchens
Karran's quartz composite is 80% natural quartz crystals bound in high-performance acrylic resin. That composition makes the bowl highly resistant to the daily abuse a kitchen sink takes: scraping pans across the bottom, setting hot cookware in the basin, and the ongoing cycle of food, grease, and cleaning agents. The Black color carries through the full material depth, so minor surface contact leaves no visible mark. The matte finish also hides water spots and light scuffs better than a high-gloss surface would, reducing the upkeep between cleaning sessions. This is a sink built for use, not just for looks.
Who This Sink Fits Best
Cabinet shops and contractors who need a reliable single-bowl black sink for a client's kitchen renovation will find the QT-671 straightforward to spec and install. Homeowners redoing a kitchen and prioritizing a clean, dark look without the complexity of an undermount installation get the full Black quartz aesthetic with a simpler path. Designers working with dark cabinetry, black hardware, or high-contrast color palettes can use this sink to anchor the kitchen without sourcing a specialty custom piece. The 25 by 22 footprint works in kitchens where counter space is at a premium but single-bowl capacity still matters.
Frequently Asked Questions
Does this sink need a special cabinet or countertop to install?
No. As a top mount drop-in, it installs into any countertop material including laminate, tile, stone, and solid surface. It requires a 30-inch or wider sink base cabinet to accommodate its 25-inch overall width.
Is the Black finish a surface coating or does it go through the material?
The color runs throughout the quartz composite body. Because the sink is 80% natural quartz bound in pigmented resin, the Black is not a separate coating that can chip or wear away from the surface.
Where does the faucet mount on a QT-671?
There is no pre-drilled faucet deck on the QT-671. The faucet mounts through the countertop behind the sink. Confirm your faucet's mounting footprint and the countertop's available drilling area before ordering.
Are a drain strainer and bottom grid included?
The QT-671 is sold as a bare sink. A drain strainer and bottom grid are sold separately. Check the Karran accessory line for compatible GR-series grids and strainers sized to this bowl.
How do I care for a black quartz composite sink?
Routine cleaning with mild soap and a soft cloth keeps the finish in good shape. Avoid abrasive scrubbers and harsh chemical cleaners, which can dull the matte surface over time. Rinse and dry the bowl after use to prevent mineral deposit buildup.
A Sink That Holds Its Look for the Long Run
The QT-671 brings a durable, full-depth Black finish into a top mount format that installs cleanly and works hard every day without demanding extra attention to keep it looking right.
