Karran Quartz Top Mount Sink For A Bold, Zero-Fuss Kitchen Install
The Karran QT812BL-PK1 is a large single bowl top mount kitchen sink in Black quartz composite, sized at 33 by 22 by 9 inches and bundled with the accessories needed to finish the installation. It drops into any standard countertop cutout from above, making it a practical choice for new builds and countertop replacements where a wipe-clean, high-contrast sink is the goal.
Key Features
• Black quartz composite construction delivers a bold, consistent color that runs throughout the material, not just on the surface.
• Top mount installation seats the sink in any countertop from above, with the rim resting on the counter surface and secured with clips below.
• Large single bowl configuration provides an uninterrupted 33 by 22 by 9 inch basin, giving full access for oversized cookware and sheet pans.
• Highly scratch, stain, chip, and heat resistant quartz composite material handles the demands of a busy kitchen wash station.
• -PK1 kit includes basket strainer, bottom grid, and Luster Pro oil, so the accessories needed to commission the sink arrive in the same box.
• Compatible with all countertop material types, from laminate to stone, because the rim covers the cut edge.
Where This Sink Earns Its Place
A top mount installation is the most straightforward path when a countertop is already in place or when the fabrication schedule doesn't allow for an undermount cutout and finish. The rim drops over the cutout edge regardless of countertop material, so this sink works equally well on laminate, butcher block, tile, quartz, and stone. The large single bowl is the right call when a divided basin would only get in the way: washing sheet pans, soaking stockpots, or running a high-volume prep station all benefit from an uninterrupted 33-inch interior. Cabinet shops fitting out a client's kitchen and contractors replacing a worn sink on an existing counter will find the drop-in method quick to plan and execute. Homeowners remodeling without a full countertop replacement get the same result.
Quartz Composite in Black: Material That Holds Its Look
Karran's quartz composite is 80% natural quartz crystals bound in 20% high-performance acrylic resin. Because the Black color runs through the full depth of the material, chips and wear don't reveal a contrasting substrate. The manufacturer rates this material as highly resistant to scratches, stains, chips, and heat, giving a working sink the durability to stay presentable in daily use. Black is a finish that coordinates cleanly with matte black faucets, dark hardware, and two-tone kitchen schemes without the maintenance that a gloss surface would demand.
The Right Fit For This Sink
This sink is built for kitchens where counter space is defined, the primary wash station sees real workload, and the install needs to be predictable. Designers specifying hardware for a kitchen renovation can pair it confidently with a single-hole or three-hole faucet mounted through the countertop or through the sink deck. Cabinet shops sourcing for volume installs will appreciate that the -PK1 kit resolves the most common missing-parts problem: the basket strainer, bottom grid, and Luster Pro care oil are already in the box. Homeowners who want a statement sink in a dark finish without complexity will find the top mount path manageable. This sink is for indoor kitchen use.
Frequently Asked Questions
Does the top mount installation require any special countertop preparation?
No unusual prep is needed. Trace the rim or use a template to mark the cutout, drill a starter hole inside the cut line, and complete the opening with a jigsaw on laminate or a router on harder surfaces. The rim covers the cut edge, so a finished countertop edge is not required.
What is included in the -PK1 kit?
The kit includes a stainless steel basket strainer, a bottom grid, and Luster Pro oil. A faucet and drain assembly are not included and are sold separately.
Will the Black finish show water spots or residue?
Dark quartz composite surfaces can show mineral deposits from hard water more visibly than lighter colors. Wiping the bowl dry after use and applying Luster Pro oil periodically keeps the surface looking its best.
Is this sink compatible with a garbage disposal?
The sink has a single bowl with a standard 3-1/2 inch drain opening. Disposal compatibility depends on the disposal brand's mounting hardware; confirm the opening size with the disposal manufacturer before purchase.
Can this sink be undermounted instead of top mounted?
No. The QT812 is a top mount model. If an undermount installation is needed for this size and material, look at the Karran QU Series quartz undermount models.
