Karran Quartz Top Mount Sink For Two-Station Kitchen Workflow
The Karran QT-720 is a double equal bowl kitchen sink in quartz composite, designed to drop into virtually any countertop material without special fabrication. Its top mount installation makes it a practical choice for new builds and kitchen refreshes alike, giving both bowls equal working depth across a 34-inch footprint.
Key Features
• Top mount installation fits into laminate, solid surface, stone, and tile countertops without seamless fabrication or edge-finishing work.
• Double equal bowl configuration supports a dedicated wash-and-rinse workflow, keeping both stations balanced in size and depth.
• Quartz composite construction combines 80% natural quartz with 20% acrylic resin for a surface that resists scratches, stains, chips, and heat.
• Gray (GR) finish integrates with a wide range of cabinet colors and countertop patterns found in contemporary kitchens.
• 9-inch bowl depth handles large cookware and baking pans without crowding either side.
Where This Sink Earns Its Place
The QT-720 fits naturally in kitchens where two people routinely share the sink, or where the cook needs one side for food prep and the other for cleanup. Because both bowls are equal in size, there is no dominant side — the layout works equally well whether the prep area is to the left or right of the primary drain station. The sink also suits any kitchen where the countertop material or fabrication timeline rules out an undermount or seamless installation. A top mount goes in cleanly and quickly, with the visible rim covering the cut edge.
Secondary prep stations in larger homes and open-concept kitchen renovations are another natural fit. The 34-inch span sits comfortably in a standard 36-inch sink base, and the equal bowl split avoids the question of which side gets the bigger run of space.
Quartz Composite Build and Gray Finish
Karran's quartz composite formula — 80% natural quartz crystals bound in 20% high-performance acrylic resin — produces a dense, non-metallic bowl surface that absorbs the daily impact of dish racks, cast iron, and hot pots without the performance anxiety of a polished stone or enameled surface. The material is highly scratch, stain, chip, and heat resistant at the bowl level, and the Gray color runs throughout rather than sitting as a surface coat, so the finish holds up through years of use without showing wear through to a different base color underneath.
Gray is a practical working finish: it does not show every water spot the way a black bowl does, and it does not read as stark white in a warmer kitchen. It coordinates across a broad range of cabinet finishes, from painted white to natural wood to two-tone combinations common in current kitchen design.
Who This Sink Is Built For
Cabinet shops and countertop fabricators installing quartz composite sinks into standard laminate or solid surface tops will find the QT mount path straightforward: no bevel-bit trimming, no seam adhesive, no Bondo work. The rim drops over the cutout and clips from below, which keeps the installation within reach for a general contractor or a competent homeowner as well as a specialty fabricator.
Designers specifying for a kitchen renovation with a fixed countertop material will appreciate that the QT-720 does not require a specific countertop type. It works above laminate, stone, and solid surface equally, which preserves flexibility when countertop selection happens after the sink is specified. Homeowners replacing an existing drop-in sink in a 36-inch base will find the 34-inch overall width a reliable fit into most standard cutouts.
Frequently Asked Questions
Does this sink require any special countertop material or fabrication method?
No. Because the QT-720 is a top mount sink, it installs over the cutout with its rim resting on the countertop surface. That means it works on laminate, solid surface, granite, quartz, and tile tops without the seamless fabrication steps required by Karran's Q Series. Trace the sink (or the included template if one is provided), mark a cut line, drill a starter hole, and cut with a jigsaw on laminate, or use a router and hard-surface template on stone.
Is the drain assembly included with the sink?
The drain assembly is not included and should be ordered separately. Confirm the drain opening size and configuration for the QT-720 against the Karran spec sheet before selecting a strainer or basket drain.
Will a standard 36-inch sink base cabinet fit this sink?
The QT-720's 34-inch overall width is designed for a standard 36-inch sink base cabinet. Verify the exact minimum cabinet size on the Karran specification sheet for this model before ordering, and check the base cabinet's interior opening against the cutout dimensions.
How does Gray compare to Black or White quartz composite in daily use?
Gray sits in the practical middle: it masks water spots and calcium deposits more readily than Black, and it does not contrast sharply against darker cabinetry the way White can. The quartz composite color runs through the bowl material rather than sitting on the surface, so everyday use does not wear through to a different color layer.
Can this sink be installed as an undermount?
No. The QT-720 is a top mount sink. For an undermount quartz installation in the same size range, Karran's QU series is the correct product family.
Two Balanced Bowls, One Durable Surface
The QT-720 brings quartz composite durability into a no-fuss top mount format that installs over any countertop and lasts through the full lifespan of the kitchen — without demanding specialized fabrication or a specific countertop material to get there.
