Bold Black Finish And A Split Bowl That Handles Real Kitchen Work
The QT-721 is a top mount quartz composite kitchen sink in Black, offering a large/small bowl configuration in a 34-inch footprint. It installs from above into the countertop cutout, making it compatible with laminate, solid surface, stone, and virtually any countertop material. The -PK1 kit includes stainless steel basket strainers, bottom grids, and Luster Pro oil so the sink is ready for use straight out of the box.
Key Features
• Top mount/drop-in installation seats into the cutout from above, covering the cut edge with the perimeter rim for a clean finish on any countertop material.
• Large/small bowl layout pairs a spacious primary wash bowl with a compact secondary bowl for prep, rinsing, or disposal duty.
• Quartz composite construction combines 80% natural quartz crystals with 20% acrylic resin, producing a surface that is highly scratch, stain, chip, and heat resistant.
• Black finish delivers a bold, high-contrast look that coordinates with matte black faucets and hardware without showing mineral deposits the way lighter sinks can.
• Included -PK1 kit contents cover stainless steel basket strainers, bottom grids, and Luster Pro oil, so no separate accessory order is needed to complete the install.
Where Top Mount Installation Earns Its Place
A top mount sink is the right call any time the countertop edge does not need to be finished for an undermount reveal, or when a project calls for simplicity and countertop flexibility. The QT-721 drops into the cutout and rests on its rim, which is then sealed with silicone and secured with the supplied clips from beneath. Because the rim sits on top of the counter, this approach works equally well on laminate, butcher block, quartz, and stone surfaces without requiring special fabrication. It is also the practical choice on a retrofit, where an existing cutout can often be reused or easily modified. The two-bowl layout rewards that versatility: the larger bowl handles pots and sheet pans, while the smaller bowl holds a colander, an ice bucket, or a disposal configuration without giving up the primary wash area.
Quartz Composite in Black: Material That Holds Up and Stands Out
Quartz composite is durable in the ways that matter for a kitchen sink. The 80% quartz content resists scratching from cookware and utensils, while the resin matrix is highly resistant to staining and chipping under daily use. Heat resistance keeps the surface stable against hot pots set briefly in the bowl. The Black color is carried through the quartz composite material, so the finish does not chip or scratch to a contrasting color underneath. Black also has a practical side in a busy kitchen: it hides the fine swirl marks and light abrasion that accumulate in lighter sinks over time. Luster Pro oil, included in the kit, restores the surface sheen and helps repel water spots during routine care.
The Right Kitchen for This Sink
Cabinet shops and contractors completing kitchen renovations will find the QT-721 sized for a standard 36-inch sink base cabinet. The top mount installation path removes any dependency on countertop fabrication specialists, which speeds scheduling and simplifies coordination on multi-trade projects. Designers specifying bold, dark kitchens will appreciate that Black quartz holds its color statement at the center of the room without requiring an all-black appliance suite to support it. Homeowners doing their own renovation can complete the install with common tools, since the drop-in method does not require bevel-bit routing or seam adhesive work. The included grids and basket strainers mean the kitchen is functional the same day the sink goes in.
Does the QT-721 work on a laminate countertop?
Yes. Because this is a top mount sink, the rim covers the cutout edge and the installation does not depend on a finished countertop surface. Laminate, quartz, stone, and solid surface all work without modification to the installation method.
Is a faucet included in the -PK1 kit?
No. The -PK1 kit includes stainless steel basket strainers, bottom grids, and Luster Pro oil. A faucet is sold separately. Because this is a top mount sink with no integral faucet deck, the faucet mounts through countertop drillings positioned behind the bowl.
How many faucet holes does the QT-721 have?
Faucet holes on a top mount quartz sink like the QT-721 are drilled through the countertop rather than the sink itself. Confirm your faucet's mounting requirements and drill accordingly when setting the cutout.
Which bowl is larger, and which side does it go on?
The QT-721 is a large/small bowl configuration. Bowl orientation — which side the large bowl sits on — is determined by the model. Check the spec sheet or confirm at the time of order if a specific orientation is required for your cabinet run and plumbing layout.
Will the Black finish fade or discolor over time?
The Black color is part of the quartz composite material itself, not a surface coating, so it does not chip to a different color underneath. Routine care with Luster Pro oil keeps the finish looking consistent, and the material is highly stain resistant under normal kitchen use.
A Complete Kit That Gets the Kitchen Moving
The QT-721 in Black delivers a durable, high-contrast quartz sink paired with the accessories to finish the job — no secondary orders required before the countertop goes down and the plumber closes out.
