A 34-Inch Double Bowl Kitchen Sink for High-Traffic Wash Stations
The Karran QT-720 is a quartz composite top mount kitchen sink in Black, designed for installations where two equal basins and a straightforward drop-in installation are the priorities. At 34 inches wide with a 9-inch depth and equal bowl configuration, this sink accommodates a dedicated wash-and-rinse setup without the additional fabrication requirements of an undermount or seamless install.
Key Features
• Quartz composite construction blends 80% natural quartz with 20% acrylic resin for a durable, hard-wearing bowl surface.
• Top mount installation drops into the countertop cutout from above, making it compatible with laminate, solid surface, stone, and most other countertop materials.
• Double equal bowl layout provides two identically sized basins, supporting wash-and-rinse or wash-and-drain workflows.
• Black finish is a through-body color, so minor surface scuffs do not reveal a different base color beneath.
• 9-inch bowl depth accommodates tall stockpots and larger cookware on both sides of the divider.
• Scratch, stain, chip, and heat resistance are documented properties of Karran's quartz composite material.
Where This Sink Earns Its Place
An equal double bowl at this width is well suited for kitchens that see heavy daily use and benefit from a clear separation between tasks. One basin handles the wash load while the other stays open for rinsing produce, thawing proteins, or staging dishes before they go to the drying rack. The divider keeps the two stations independent without any coordination needed between users sharing the sink.
Top mount installation also means this sink is a practical retrofit option. If an existing laminate or post-form countertop is staying in place, the QT-720 drops into a new cutout without requiring edge finishing or the bonding steps an undermount installation would involve. It works equally well in new construction across countertop types.
Quartz Composite in Black: Material and Durability
Karran's quartz composite is an 80/20 blend of natural quartz crystals and acrylic resin, pressed into a non-porous bowl. The material resists the scratches, stains, chips, and heat that accumulate over years of kitchen use. In Black, the color runs through the body of the material rather than sitting as a surface layer, which keeps the finish looking consistent as the sink ages. The matte texture that comes standard with this color also tends to show water spots less than a high-gloss surface would.
Daily care requires only mild soap and water. Avoid abrasive pads or harsh chemical cleaners, which can dull the surface over time.
Who Should Specify This Sink
Kitchen remodelers and designers looking for a durable black sink that installs without specialized fabrication will find the QT-720 a straightforward specification. Cabinet shops outfitting display kitchens or finishing client projects with laminate countertops can install this sink without sourcing additional bonding materials or template routing equipment. Homeowners replacing an existing drop-in sink who want a long-wearing, easy-to-match quartz material are also a natural fit, particularly those drawn to the clean look of an equal double bowl in a dark colorway.
Frequently Asked Questions
Does this sink require a special cabinet size?
The sink's overall width is 34 inches. A standard 36-inch sink base cabinet is the typical fit, but confirm the actual cabinet opening and countertop dimensions before cutting. The spec sheet lists the minimum cabinet size for this model.
Is a drain or strainer included with the sink?
Drain assemblies and basket strainers are not included with the bare QT-720 and need to be sourced separately. Match the strainer to the sink's drain opening size.
Where does the faucet mount on a top mount quartz sink?
Top mount quartz sinks in this series mount the faucet through the countertop or through pre-drilled holes in the sink's deck, depending on the model. Check the spec sheet for the faucet hole configuration on the QT-720.
Can this sink be installed in a solid surface or stone countertop?
Yes. Top mount installation is compatible with most countertop materials, including laminate, solid surface, granite, and quartz countertops. No seamless bonding is required for top mount; the rim rests on the counter surface and is sealed with silicone.
Is the Black color consistent through the material, or is it a surface coating?
The color is integral to the quartz composite material, not a surface paint or coating. Minor scuffs will not reveal a different color underneath.
Two Basins, One Decision Simplified
The QT-720 brings together a proven quartz composite build, an equal double bowl layout, and a drop-in installation path that works across countertop types. For projects where durability, ease of installation, and a bold Black finish all need to show up in the same sink, this one covers the brief.
