Karran Quartz Top Mount Sink For Two-Station Kitchen Workflows
The Karran QT-721 is a 34 by 22 by 9 inch quartz composite top mount kitchen sink in White, configured in a large/small bowl layout that separates the primary wash station from a dedicated prep or rinse side. It installs from above into a standard sink base cutout, making it compatible with virtually any countertop material, and ships as a complete kit with the accessories needed to start using it immediately.
Key Features
• Top mount installation drops into new and existing countertops from above, with the rim covering the cut edge for a finished look on any countertop material.
• Large/small bowl configuration dedicates the bigger basin to washing and the smaller bowl to prep, rinsing, or a garbage disposal drop.
• Quartz composite construction combines 80% natural quartz crystals with 20% acrylic resin for a surface that is highly scratch, stain, chip, and heat resistant.
• White finish provides a bright, clean look that pairs with a wide range of countertop colors and cabinet styles.
• Kit includes stainless steel basket strainers, bottom grids, and Luster Pro oil so the sink is ready to use right out of the box.
Two Bowls, One Efficient Workspace
A large/small bowl layout is the workhorse of a busy kitchen. The larger basin handles the heavy lifting: soaking pots, washing sheet pans, and managing the daily dish load. The smaller bowl stays free for prep rinsing, draining pasta, or running a garbage disposal without interrupting the main wash side. This configuration suits households that hand-wash frequently, cooks who work with oversized cookware, and kitchens where two people share the sink at the same time. The included bottom grids protect the quartz floor of each bowl during regular use, and the stainless steel basket strainers catch debris before it reaches the drain.
Quartz That Works as Hard as the Kitchen Does
Quartz composite is not a cosmetic material choice. The 80% natural quartz and 20% acrylic resin blend delivers resistance to scratches from utensils and pots, stains from coffee and food dyes, chips at the bowl edges, and the heat of a pot pulled directly from a burner. The White colorway runs through the full depth of the material, so minor surface wear does not expose a contrasting base color. The top mount rim covers the countertop cutout edge cleanly, which means there is no exposed raw edge to seal or finish on laminate, tile, or stone. Installation follows the standard drop-in method: trace the sink perimeter, cut the opening, drop the sink in, and secure from below with the supplied clips.
The Right Fit for Renovation and New Construction
This sink works equally well in a full kitchen build and in a countertop replacement where the cabinet box is already in place. Because the rim sits on top of the counter surface, the QT-721 does not require the countertop to be fabricated for an undermount reveal, and there is no exposed edge to polish or wrap. Designers specifying for rental properties and contractor remodels will find the White quartz surface neutral enough to coordinate across paint colors and hardware finishes. Cabinet shops building kitchen packages can include the sink kit as a line item, with the grids, strainers, and Luster Pro oil already accounted for. Homeowners tackling a weekend renovation get a complete kit that needs no additional accessory sourcing before the sink goes in.
Frequently Asked Questions
What countertop materials work with this sink?
Because the QT-721 is a top mount sink, its rim rests on top of the counter surface rather than bonding beneath it. That means it is compatible with laminate, tile, solid surface, quartz, granite, and most other countertop materials, as long as the base cabinet and cutout support the sink's 34 by 22 inch footprint.
What ships in the kit?
The -PK1 kit includes the QT-721 sink, stainless steel basket strainers, bottom grids for each bowl, and Luster Pro oil. A drain assembly is not included and is sold separately.
Which side is the large bowl on?
Take the bowl orientation from the model number and the spec sheet for the QT-721. If your layout requires a specific handed configuration, verify the orientation before ordering — bowl-specific accessories such as the included grids are matched to each basin.
Is this sink the same as Karran's Q Series seamless line?
No. The QT-721 is from the QT top mount series, which installs above the counter. Karran's Q Series is a separate quartz line engineered for seamless undermount installation in laminate and solid surface countertops using a bevel-bit method. The QT-721 is not rated for seamless installation.
What minimum cabinet size does this sink require?
At 34 inches wide overall, the QT-721 is designed for a 36 inch sink base cabinet. Confirm the cutout dimensions against the actual cabinet opening before cutting, since the spec sheet dimensions are nominal.
A Complete Kit, Ready for the Countertop
The QT-721 brings together a two-station quartz bowl, proven drop-in installation, and the accessories to finish the job in a single order, so the kitchen project keeps moving without an extra trip for strainers or a follow-up delivery for grids.
