A Top Mount Double Bowl in Concrete Quartz for Hardworking Kitchens
The Karran QT-720 is a quartz composite top mount kitchen sink in Concrete, offering a double equal bowl layout in a 34-inch format that drops into new and existing countertops without specialized fabrication tools or techniques. Built from 80% natural quartz and 20% acrylic resin, it brings lasting material quality to a straightforward drop-in installation.
Key Features
• Top mount installation fits standard countertop cutouts in laminate, solid surface, stone, and tile without special tooling.
• Double equal bowl configuration supports a dedicated wash side and a dedicated rinse or prep side simultaneously.
• Concrete color delivers a muted, industrial-modern aesthetic that pairs naturally with grey, white, and woodgrain cabinetry.
• Quartz composite construction (80% quartz, 20% acrylic resin) is highly scratch, stain, chip, and heat resistant for daily kitchen use.
• 9-inch bowl depth accommodates large pots, sheet pans, and deep cutting boards without water splashing over the rim.
Where a Drop-In Double Bowl Delivers
The top mount format is the most versatile installation path in kitchen sinks. The rim sits on top of the countertop surface and covers the cutout edge, which means it works on laminate without bevel-bit preparation, on existing stone countertops during a sink swap, and on any countertop material type a homeowner or contractor is working with. There is no specialized adhesive method required, no rim finishing, and no flush-trimming step. The sink drops in, clips secure it from below, and the install is done.
The equal double bowl layout suits kitchens where the two-station workflow matters: one side holds soapy wash water while the other handles rinsing, or one side stays clear for prep while the other is in active use. Households that hand-wash dishes, cooks who break down vegetables on one side and wash on the other, and cabinet installers finishing a kitchen remodel all reach for this configuration for the same reason — two bowls at the same depth means neither side is the compromise.
Quartz Composite in Concrete
Quartz composite sinks resist the everyday abuse that kitchen sinks absorb: cutting board scrapes, hot water from boiling pots, coffee and wine stains, and general impact. The material is highly scratch, stain, chip, and heat resistant, which means it handles a normal kitchen workload without the coddling a polished stainless or fireclay surface can require. The Concrete color reads as a warm, desaturated grey rather than a cold industrial tone, so it reads at home in both contemporary and transitional kitchens. It coordinates especially well with grey and greige quartz countertops, concrete-look porcelain, and light-stained oak or maple cabinetry without demanding a matching countertop material or finish.
The Right Fit for This Sink
The QT-720 is a strong fit for kitchen remodels where the countertop is staying in place and only the sink is being replaced. The top mount format handles that swap without a fabricator on site. It also suits new builds where the design calls for a double bowl in a color that goes beyond white or grey. Cabinet shops installing complete kitchen packages find the drop-in format efficient: the countertop ships, the sink drops in on-site, and no specialized stone-work crew is needed to finish the install. Homeowners doing their own renovation work will find the install path familiar and manageable. Designers specifying this sink can rely on the Concrete finish to hold its look over time without polishing schedules or special cleaners.
Frequently Asked Questions
Does the Concrete color vary by batch, or is it consistent across orders?
Quartz composite color is set in the material itself rather than applied as a surface coat, so the Concrete shade is consistent and does not fade, stain through to a different base color, or vary significantly between production runs.
Can this sink be installed in a laminate countertop?
Yes. Top mount installation works in laminate, solid surface, granite, quartz countertops, tile, and other standard countertop materials. The rim covers the cutout edge, so there is no exposed laminate to seal or trim.
What minimum cabinet width does the QT-720 require?
The sink is 34 inches wide overall. Confirm the minimum cabinet size against your sink base before ordering, as Karran publishes a minimum cabinet size on the spec sheet for each model.
Is a drain or strainer included with the sink?
The drain assembly is not included and should be ordered separately. Confirm the drain opening size from the Karran spec sheet for this model to select a compatible strainer.
Where does the faucet mount on a top mount quartz sink?
The QT-720 has a faucet deck behind the bowls. Faucet drillings are positioned on that deck; check the spec sheet for the hole count and spacing before selecting a faucet.
Built for the Install Path You Already Have
The QT-720 in Concrete earns its place in a kitchen by making the install straightforward and the daily use low-maintenance: drop it in, connect the drain and faucet, and get back to the job without a fabricator visit or a polishing kit on the counter.
