A Double-Basin Sink Built for the Two-Station Kitchen Workflow
The Karran Q-350 is a quartz composite, double equal bowl undermount kitchen sink that installs seamlessly into laminate and solid surface countertops, making it the go-to choice for fabricators who want a clean, rim-free transition from counter to bowl. Its 32-3/8 by 19 inch footprint fits a standard 33 inch sink base, and the two matched basins keep wash and rinse duties separate without sacrificing space on either side.
Key Features
• Seamless undermount installation in laminate and solid surface countertops using Karran's documented bevel-bit method, leaving no exposed rim or seam.
• 80% quartz and 20% acrylic resin construction delivers a surface that is highly scratch, stain, chip, and heat resistant under daily kitchen use.
• 535°F heat resistance means hot pots and pans from the stovetop won't damage the bowl surface.
• Double equal bowl configuration provides two matched basins for dedicated wash-and-rinse or prep-and-clean workflows.
• White finish coordinates cleanly with light countertop palettes, cabinetry, and appliances in a broad range of kitchen styles.
• No faucet deck on the sink body, so the faucet and any accessories mount through the countertop behind the bowl.
Where the Two-Bowl Layout Earns Its Place
Equal double-bowl sinks shine in households and light commercial kitchens where the workflow divides naturally into two stations. Fill one side with hot soapy water for washing; keep the other clear for rinsing, draining, or staging cut produce. For a cabinet shop or showroom kitchen display, the balanced layout photographs symmetrically and reads as a deliberate design choice rather than an afterthought. The 32-3/8 inch length keeps the footprint modest enough for a standard 33 inch sink base while still delivering two functional basins. Faucet and soap dispenser holes drill through the countertop directly, so the counter material and layout dictate placement rather than a fixed deck.
Quartz Composite Construction in White
Karran's quartz composite blends 80% natural quartz crystals with 20% high-performance acrylic resin. The result is a bowl that handles the abrasion of daily scrubbing, resists staining from coffee, wine, and food acids, and tolerates heat to 535°F without warping or discoloring. White quartz composite reads differently than a white porcelain or vitreous china bowl: the matte, stone-like surface absorbs light rather than reflecting it, which tends to hide minor water spots and surface variations better under bright task lighting. The color is consistent through the thickness of the material, so minor surface scuffs don't expose a different color underneath.
The Right Fit for Laminate and Solid Surface Kitchens
The Q-350 belongs to Karran's Q Series, which is specifically documented for seamless undermount installation in laminate and solid surface countertops. That capability matters most to fabricators and kitchen remodelers working in those materials, where a conventional undermount rim would require a finished countertop edge and visible gap. With the Q Series bevel-bit method, the counter flows directly into the bowl with no interruption. This sink is not the standard undermount choice for stone, granite, or quartz countertops — for those substrates, the QU Series is the right route. Homeowners renovating a laminate kitchen, cabinet shops building laminate-top displays, and designers specifying a seamless countertop-to-sink transition will find this the product the installation calls for.
Frequently Asked Questions
Does this sink work with granite or quartz stone countertops?
The Q Series is documented for seamless installation in laminate and solid surface countertops. For granite, quartz stone, or similar hard-surface tops, the Karran QU Series is the right undermount choice for that substrate.
Are the template and mounting clips included with the Q-350?
Per Karran's Q Series specification, neither a paper template nor mounting clips are included with the sink. The Q Series installs using the bevel-bit seamless method, which has its own tooling and adhesive requirements.
Where does the faucet mount on this sink?
The Q-350 has no faucet deck. The faucet, soap dispenser, and any other accessories mount through holes drilled in the countertop behind the bowl. The number and placement of those holes depend on the countertop fabrication.
What drain size does each bowl use?
Standard kitchen bowl drains in this series use a 3-1/2 inch drain opening. Confirm the exact value with the specification sheet before ordering strainers or basket hardware.
Is the drain assembly included?
No drain assembly is included. Basket strainers or drain hardware for both bowls are ordered separately and should be confirmed to fit a 3-1/2 inch opening.
A Clean Countertop Transition, Delivered in White
For any kitchen project where the laminate or solid surface countertop deserves a sink that disappears into it rather than sitting on top of it, the Q-350 delivers a seamless, durable, and visually balanced solution in a finish that works from modern to transitional to classic.
