Karran Quartz Undermount Sink For Equal-Station Kitchen Workflows
The Karran QU-710 is a double equal bowl quartz composite undermount kitchen sink finished in Concrete, sized to fit a standard 36-inch sink base. Its two symmetrical basins support a dedicated wash-and-rinse setup without sacrificing workspace on either side, and the 9-inch bowl depth handles large cookware with ease.
Key Features
• Quartz composite construction combines 80% natural quartz crystals with 20% acrylic resin for a surface that is highly resistant to scratches, stains, chips, and heat.
• Double equal bowl layout gives both basins the same dimensions, so neither side compromises on working space.
• Undermount installation keeps the rim concealed beneath the countertop for a clean sightline and easy counter-to-sink sweeping.
• Concrete finish is a muted, neutral grey tone that works across a range of cabinet colors and countertop materials without competing with them.
• No faucet deck means the faucet and any accessories mount through the countertop, keeping the sink profile uncluttered.
• 9-inch bowl depth on both basins accommodates tall stockpots, large baking sheets, and full-size roasting pans without overflow concerns.
Where Two Equal Bowls Make the Difference
An equal double bowl sink works best when the kitchen genuinely needs two stations rather than one large and one auxiliary. A wash-and-rinse routine is the classic case: soaking dishes on one side while rinsing produce or defrosting proteins on the other, without either task crowding the other out. The symmetrical layout also suits households that hand-wash frequently, since both sides can hold water independently. For cabinet shops, design showrooms, or installers specifying the kitchen, the equal configuration reads as straightforward and versatile, with no handed orientation to track on the order.
Quartz Composite in Concrete
Quartz composite sinks sit in a different durability tier than stainless or acrylic. The 80% quartz content gives the material its hardness and resistance, while the acrylic resin binds it into a consistent surface that resists staining from common kitchen acids and pigments. The Concrete color is a warm grey with visible depth rather than a flat painted-on shade — it reads as intentional rather than neutral-by-default, and it pairs naturally with both light and dark countertop materials. Unlike a polished stainless finish, the Concrete quartz surface does not show water spots or light surface scratches in normal light, which keeps the sink looking clean between wipes. This sink is for indoor kitchen use.
Who This Sink Is Built For
Homeowners planning a kitchen remodel around solid surface, granite, or quartz countertops will find the QU-710 a straightforward undermount choice in a size that covers most 36-inch sink base situations. Designers specifying contemporary or transitional kitchens can use the Concrete finish to anchor an otherwise light palette or complement concrete-look tile and laminates. Cabinet shops and contractors installing new construction will appreciate that the equal bowl layout requires no orientation call — either installation direction works — and that the sink's dimensions translate cleanly across a wide range of countertop materials. The quartz composite surface holds up to the demands of an active household without the acoustic ring of stainless or the maintenance concerns of a light-colored ceramic.
Does the QU-710 work with granite or quartz countertops?
Yes. The QU-710 is designed for undermount installation in stone countertops including granite and quartz, as well as solid surface. The flat mounting rim and no-deck design are well suited to these materials, where the faucet mounts through the countertop itself.
Does this sink come with mounting clips or a template?
Clips and a paper template are not included with the QU Series. Your countertop fabricator will use the actual sink as the guide for the cutout, which is standard practice for undermount installations in stone and solid surface.
Where does the faucet mount on the QU-710?
The QU-710 has no faucet deck, so the faucet and any accessories such as a soap dispenser mount through the countertop behind the sink. Hole placement and count are determined during countertop fabrication.
Is a drain or strainer included?
The QU-710 is sold as a bare sink. Basket strainers and a bottom grid are not included and are ordered separately. Check the accessories section for compatible components sized to this model's drain openings.
How does the Concrete finish hold up over time?
The Concrete color runs through the quartz composite material rather than sitting on the surface as a coating, so it does not fade or chip the way a painted or powder-coated finish can. The 80% quartz content makes it highly resistant to scratches, stains, and heat from normal kitchen use.
A Workhorse Sink That Earns Its Place
The QU-710 in Concrete pairs the durability of quartz composite with a finish color that ages well and complements a wide range of kitchens — giving fabricators, contractors, and homeowners a double-bowl undermount that is easy to specify, straightforward to install, and built to perform through years of daily use.
