An Undermount Kitchen Sink Built Around How Work Actually Flows
The Karran QU-711 is a quartz composite undermount kitchen sink in a large/small bowl configuration, designed for kitchens where a dedicated prep side and a generous wash side each need their own space. Its 80% quartz, 20% acrylic resin construction and Gray finish pair with quartz, granite, and solid surface countertops for a clean, rimless installation.
Key Features
• Large/small bowl layout puts a deep primary wash basin alongside a compact prep or rinse basin in a single 32-1/2 by 19-1/2 inch footprint.
• Quartz composite construction (80% quartz, 20% acrylic resin) delivers high resistance to scratches, stains, chips, and heat in daily kitchen use.
• Undermount installation positions the sink beneath the countertop, leaving no exposed rim and a clean, wipe-down counter edge.
• Nine-inch bowl depth provides room for large pots and sheet pans without water splashing over the sides.
• No faucet deck means the faucet and any accessories mount through the countertop, keeping the bowl area unobstructed.
• Gray finish coordinates across kitchen hardware and countertop tones without locking you into a single aesthetic direction.
Two Stations, One Sink
A large/small bowl sink solves a real workflow problem: not every task belongs in the same basin. The QU-711 separates the heavy washing from the lighter prep work so both can happen at the same time without crowding. Soaking a cast iron pan on one side while rinsing vegetables on the other, or running a colander in the smaller bowl while the larger bowl holds the main cleanup — these are the moments the configuration is built for. At 32-1/2 inches wide, the sink fills a standard 33-inch minimum cabinet run without demanding an oversized base, and the 9-inch depth gives both bowls enough room to handle cookware that won't fit in a shallower basin.
Quartz Composite in Gray
The quartz composite material resists the scratches, stains, chips, and heat that come with everyday kitchen work — not because it is indestructible, but because the 80% quartz content makes the surface genuinely hard and the resin binds it without creating a brittle shell. The Gray color runs through the material rather than sitting on top of it, so minor surface contact doesn't expose a contrasting substrate. Because the QU-711 is a QU Series undermount model, it is not a seamless-installation sink — it undermounts conventionally beneath quartz, granite, and solid surface countertops using a reveal (positive or negative, agreed with the fabricator before the cut). The flat rim sits concealed under the counter, and the faucet drills through the countertop deck behind the bowl. No template or clips are included with this model; coordinate with your fabricator before ordering those items.
The Right Fit for This Sink
The QU-711 suits kitchens where two people regularly share the sink, households that cook in volume and hand-wash a lot of cookware, and renovation projects where the countertop material is quartz, granite, or solid surface and a clean undermount edge is the goal. Cabinet shops and designers specifying for a remodel will find the standard 32-1/2 inch width easy to accommodate in most sink base layouts. Homeowners who want a hard-working sink that doesn't demand a specialty countertop fabrication process will find the conventional undermount path straightforward for a qualified installer.
Does the QU-711 work with laminate countertops?
No. The QU Series uses conventional undermount installation, which requires a countertop material — quartz, granite, or solid surface — that can support an undermount edge. Laminate is not a documented countertop match for this model. For laminate, the Q Series seamless line is the appropriate choice.
Which bowl is the large bowl and which is the small?
On the QU-711, the large bowl sits on the left and the small bowl on the right, as indicated in the SAP model code (LH/LG for left-hand large, RH/SM for right-hand small). Confirm orientation against your cabinet run before finalizing the order.
Are clips, a template, or a drain included?
No. The QU Series spec documentation states that clips and templates are not included. Drain components are also sold separately. Source these through your fabricator or as add-on items before the installation date.
Can the faucet mount on the sink itself?
No. QU Series sinks have no faucet deck. The faucet, soap dispenser, and any other deck accessories mount through holes drilled in the countertop behind the bowl.
A Sink That Earns Its Place on Day One
The QU-711 gives a busy kitchen two dedicated work zones in a single undermount package — hard-wearing quartz composite construction, a Gray finish that holds its look through daily use, and a footprint sized to fit the standard sink base without modification.
