Divided Workspace, Seamless Countertop Fit
The Karran QU-711 is a large/small bowl quartz composite undermount kitchen sink designed for homeowners and cabinet shops installing into granite, quartz, or solid surface countertops. Its two-basin layout delivers the flexibility of a dedicated prep side without sacrificing the capacity of the main wash bowl, all in a 32-1/2 inch footprint that fits a standard 33 inch sink base.
Key Features
• Large/small bowl configuration pairs a primary wash basin with a separate, shallower prep or disposal side for a cleaner workflow.
• Quartz composite construction (80% natural quartz, 20% acrylic resin) resists scratches, stains, chips, and heat during daily use.
• Undermount installation positions the sink below the countertop edge for a clean, wipe-down counter surface with no exposed rim.
• 9-inch bowl depth on the large side handles deep stockpots and sheet pans without splashing.
• White finish integrates readily with light-toned countertops and cabinet interiors.
• Flat mounting rim with no faucet deck keeps the faucet and accessories mounted through the countertop, giving the bowl full edge-to-edge interior space.
Where the Two-Bowl Layout Earns Its Place
A divided sink changes how the kitchen actually works. The large bowl handles the heavy lifting: soaking a roasting pan, washing produce, or running full-rack dish cleanup. The small bowl steps in as a dedicated rinsing station, a disposal drop zone, or a cold-water hold during meal prep. For households that cook regularly, or for a designer specifying for a client who does, the unequal split is almost always more useful than either a single bowl or an equal double — you get meaningful capacity on both sides without either bowl feeling undersized.
At 32-1/2 inches overall, the QU-711 is a natural fit for a 33 inch sink base cabinet, the most common width in residential kitchen runs. The undermount profile keeps countertop cleanup straightforward: crumbs and spills wipe directly into the bowl with no rim lip to trap debris.
Quartz Composite Built for the Kitchen Environment
Karran's quartz composite is 80% natural quartz crystals bound in 20% acrylic resin. That ratio gives the bowl its weight and hardness while keeping it resistant to the scratches, stains, chips, and heat that accumulate in an active kitchen. The White color runs through the full thickness of the material, so surface wear does not expose a different color beneath. Because the QU-711 has a flat mounting rim and no integral faucet deck, the faucet mounts through the countertop — keeping the counter surface continuous and the bowl's rim profile low.
Undermounting in quartz, granite, or solid surface is the appropriate application for the QU series. The flat rim allows either a small positive or negative reveal, agreed with the fabricator before cutting. The drain opening accepts a standard 3-1/2 inch kitchen basket strainer; the drain assembly and mounting clips are not included with the sink and should be sourced separately.
The Right Sink for Renovation and New Construction Alike
Cabinet shops and countertop fabricators running production kitchens will find the QU-711 straightforward to specify and install: a known footprint, a standard undermount method, and a neutral White finish that works across the broadest range of countertop and cabinet combinations. For a homeowner renovating a kitchen with an existing 33 inch sink base, it drops into the same cabinet opening with no structural changes needed. Designers specifying for clients who do a lot of cooking will find the large/small split more practical than the 50/50 configuration for most households.
Frequently Asked Questions
Does the QU-711 install seamlessly into a laminate countertop?
No. Seamless laminate installation is specific to Karran's Q Series. The QU-711 is a standard undermount designed for quartz, granite, and solid surface countertops, where the fabricator finishes the countertop edge and the sink mounts beneath it with a conventional reveal.
Which bowl is larger, and how are they oriented?
The SAP data identifies a left large/right small bowl orientation (LH large, RH small). Confirm the exact per-bowl dimensions against the Karran spec sheet before finalizing the cutout, as bowl dimensions differ from the overall 32-1/2 by 19-1/2 inch footprint.
Is the drain assembly included?
No. The drain assembly is sold separately. Plan to order a 3-1/2 inch basket strainer for each bowl at the same time as the sink.
Where does the faucet mount on this sink?
The QU-711 has no faucet deck, so the faucet mounts through the countertop. Coordinate faucet hole placement with the countertop fabricator before cutting.
What countertop materials work with undermount installation?
The QU series is documented for undermounting in quartz, granite, and solid surface countertops. For laminate installations, look to the Karran Q Series instead.
A Kitchen Sink That Works as Hard as the Kitchen Does
The QU-711 brings the practical advantages of a divided basin and a clean undermount profile to one of the most-used surfaces in the home. Specify it with confidence for any stone or solid surface countertop project where a 33 inch sink base and a two-bowl workflow are on the plan.
