An Undermount Sink Built for a Split-Station Kitchen Workflow
The Karran Q-360R is a large/small bowl quartz composite undermount kitchen sink that installs seamlessly in laminate and solid surface countertops, giving you a designated wash station on one side and a dedicated prep or rinse station on the other. The Gray finish integrates naturally into a range of countertop palettes without competing for attention.
Key Features
• Seamless undermount installation in laminate and solid surface countertops using Karran's documented bevel-bit method, with no exposed rim between counter and bowl.
• Large/small bowl configuration separates the primary wash station from a secondary prep or disposal area within a single footprint.
• Quartz composite construction made from 80% natural quartz crystals and 20% acrylic resin, rated by Karran as highly scratch, stain, chip, and heat resistant.
• Right-side small bowl orientation positions the larger wash bowl on the left and the compact prep bowl on the right, matching the standard left-to-right kitchen workflow.
• No faucet deck on this undermount model means the faucet and any accessories mount through the countertop, keeping the bowl area uncluttered.
• Gray quartz finish is a consistent, through-body color that resists showing wear at high-use edges and corners.
Where the Split-Bowl Layout Earns Its Place
A large/small bowl sink works best in kitchens where two tasks are running at the same time. The larger bowl holds a soak or a colander of produce while the smaller bowl stays free for rinsing, dumping vegetable scraps, or running a garbage disposal. For households that hand-wash dishes alongside cooking, the separation keeps rinse water clean. For kitchen designers, specifying the Q-360R in a 33-inch or wider sink base gives the primary cook enough room to work either bowl without reaching across a congested counter. The R suffix on this model places the small bowl on the right, which suits the most common right-handed, left-to-right prep arrangement.
Quartz Composite Construction in Gray
Quartz composite is the right material when the countertop sees heavy daily use. The 80% quartz content keeps the bowl surface hard enough to resist scratching from pots, pans, and cutlery slippage, while the acrylic resin binder gives the material some flex so it resists chipping at the rim during installation and over time. Karran rates this material as highly resistant to scratches, stains, chips, and heat. The Gray color runs through the body of the material rather than sitting as a surface coat, so visible wear at high-contact spots is far less likely than with a painted or enameled finish. The matte surface also softens the look of water spots compared with a polished stainless bowl.
The Right Fit: Fabricators, Designers, and Serious Home Kitchens
This sink suits three buyer types equally well. Fabricators working in laminate and solid surface will recognize the Q Series as Karran's seamless line and know the bevel-bit and seam-adhesive steps. Designers specifying for a renovation where the countertop is laminate or solid surface can call out the Q-360R-GR with confidence that the install path is documented. Homeowners upgrading an existing laminate kitchen get a split-bowl sink that looks built-in rather than dropped in, without tearing out the counter. Note that this installation method is specific to laminate and solid surface countertops. For installations in stone or quartz countertops, Karran's QU series is the better route. Template and mounting clips are not included with Q Series sinks; confirm with your fabricator that the full installation kit is on hand before starting the cutout.
What countertop materials work with the Q-360R?
Karran documents seamless undermount installation for the Q Series in laminate and solid surface countertops. For stone, quartz, or granite countertops, the QU undermount series uses standard undermount methods instead.
Are the template and mounting clips included?
No. Karran Q Series spec sheets state that the template and clips are not included. Your fabricator will need to source the appropriate clips and confirm the cutout method before beginning.
Where does the faucet mount on this sink?
The Q-360R has no faucet deck. The faucet, soap dispenser, and any other accessories mount through drillings in the countertop behind the sink.
Which bowl is larger, and which side is it on?
The R in the model designation indicates the small bowl is on the right and the large bowl is on the left. If the opposite orientation suits your layout, check the Q-360 family for an L-suffix variant.
How durable is the Gray quartz finish over time?
The Gray color runs through the body of the quartz composite material rather than being applied as a surface coating, so edge wear and chipping are less likely to expose a contrasting color underneath. Karran rates the material as highly scratch, stain, chip, and heat resistant.
A Sink That Keeps the Kitchen Working
The Q-360R delivers a split-station workflow, a durable quartz composite bowl, and a seamless countertop integration in one undermount package, giving any laminate or solid surface kitchen a sink that functions like a built-in fixture rather than an afterthought.
