A Drop-In Double Bowl Sink Built for the Workhorse Kitchen
The Karran QT-720 is a quartz composite top mount kitchen sink in White that installs into any countertop material from above, making it a versatile fit for new builds and renovation projects alike. Its equal double bowl layout gives both sides of the kitchen an evenly matched workspace, and the quartz composite construction holds up through years of daily cooking, cleaning, and prep.
Key Features
• Top mount installation drops into the countertop cutout from above and works with laminate, stone, solid surface, and tile countertops.
• Equal double bowl configuration gives each side identical interior dimensions, supporting a dedicated wash-and-rinse setup or splitting prep duties between two cooks.
• Quartz composite construction (80% natural quartz, 20% acrylic resin) delivers high resistance to scratches, stains, chips, and heat in daily kitchen use.
• White finish offers a clean, neutral look that pairs with both traditional and contemporary kitchen designs.
• 34 x 22 x 9 inch overall footprint suits standard 36 inch base cabinet runs with room for a faucet drilling in the countertop behind the rim.
Where This Sink Fits the Work
Top mount installation is one of the most practical paths when the countertop is already in place. Because the sink's rim rests on top of the counter surface and clips fasten from below, there is no need to modify the countertop edge or use a special fabrication method. That makes the QT-720 a go-to choice for laminate kitchen renovations where an undermount or seamless approach would require countertop replacement, and it works equally well during new construction in stone, solid surface, or tile where the buyer simply wants a reliable, straightforward install.
The equal double bowl layout supports kitchens where two tasks run at the same time: wash water on one side, rinse on the other, or produce prep beside a full pot of soaking cookware. Neither bowl is the afterthought that shows up in offset configurations.
Quartz Composite in White: Material and Durability
Quartz composite is not a coated surface. The color and the scratch and stain resistance run through the full depth of the material, made from 80% natural quartz crystals bound in 20% acrylic resin. In a White kitchen sink, that means chipping or hard impacts reveal the same White material beneath rather than a contrasting substrate. Daily contact with cookware, acidic foods, and household cleaners sits well within what this material handles, and the non-porous surface does not require sealing. The White colorway works in kitchens where the hardware and appliances run light, or as a contrast element against darker countertops and cabinetry.
Who Uses This Sink and Where It Works Best
Cabinet shops and contractors specifying a kitchen package for a client who wants a clean, low-maintenance sink without a custom countertop install will find the QT-720 straightforward to source and fit. Designers working on a mid-range kitchen renovation where the countertop stays in place can specify it without a fabrication conversation. Homeowners replacing an older drop-in sink appreciate that the rim covers the existing cutout edge, hiding any wear from the previous install. The 34 inch width is a well-established standard for 36 inch sink base cabinets, so clearance to the cabinet walls is typically adequate without a job-site measurement.
Does this sink require a special countertop material to install?
No. Because it installs from above with the rim resting on the countertop surface, it works with laminate, stone, solid surface, tile, and most other countertop materials. This is one of the main advantages over seamless or undermount approaches that are limited to specific counter types.
Where does the faucet mount on this sink?
The QT-720 has no faucet deck. The faucet mounts through the countertop behind the sink rim, so the number and spacing of faucet holes depend on the countertop and the faucet chosen, not on the sink itself.
Are grids, strainers, or a drain assembly included with this sink?
The QT-720 is sold as a bare sink. Basket strainers, bottom grids, and drain assemblies are sold separately. Confirm the drain opening size from the spec sheet when selecting strainers.
Can this sink replace an existing drop-in sink without cutting a new hole?
In many cases, yes. The 34 x 22 inch overall dimensions match a common standard for double bowl drop-in sinks, so the existing cutout may align. Measure the current opening and compare it against the QT-720's required cutout dimensions before ordering to confirm fit.
Two Full Bowls, One Dependable Install
The QT-720 delivers equal workspace on both sides of the kitchen sink without the countertop complexity of an undermount approach, making it a practical specification for projects where installation simplicity and material durability both matter.
