A Double Bowl Kitchen Sink Built for Seamless Integration in Laminate and Solid Surface
The Karran Q-350 is a quartz composite undermount double bowl kitchen sink that installs seamlessly into laminate and solid surface countertops, leaving no exposed rim or visible seam where the counter meets the bowl. In Concrete, it delivers a muted, industrial-cool tone that works equally well in modern and transitional kitchens.
Key Features
• Seamless undermount installation bonds the sink flush with laminate and solid surface countertops for a clean, uninterrupted surface.
• Equal double bowl configuration supports dedicated wash-and-rinse or wash-and-prep workflows without splitting counter space unevenly.
• 80% quartz / 20% acrylic resin construction gives the bowl high resistance to scratches, stains, chips, and heat in daily kitchen use.
• Concrete color finish offers a warm neutral tone that pairs naturally with white, grey, and wood-tone cabinetry.
• No faucet deck on the sink body means the faucet and any accessories mount through the countertop, keeping the bowl perimeter clear.
• Template and clips are not included, so the fabricator works directly from the sink or a downloaded DXF cutout file.
Where This Sink Earns Its Place in the Kitchen
A two-station bowl setup makes the most sense when the kitchen handles real volume: washing produce on one side while soaking a pan on the other, or keeping a rinse station clear while the cook works. The Q-350's equal bowls make neither side the afterthought, which matters in kitchens where two people work the sink at once. Because the installation method bonds the sink flush with the counter, there is no rim ledge to trap water or crumbs — just a continuous wiping surface from the counter into the bowl. That advantage is specific to laminate and solid surface countertops, where the seamless fabrication method applies. For quartz, granite, or stone countertops, a standard undermount approach is the right path.
Material Built to Handle a Working Kitchen
Quartz composite at this composition — 80% natural quartz crystals bound in acrylic resin — sits well above entry-level stainless in everyday durability terms. The material resists the scratches that come from sliding pots, the stains from coffee and wine, and the thermal shock that can mark softer surfaces. The Concrete color runs through the material, so minor surface wear does not show as a contrasting color. The matte texture also reduces visible water spots compared to high-gloss finishes, which is a practical advantage in a busy kitchen sink.
Who Specifies the Q-350 and Why
Cabinet shops and countertop fabricators working in laminate or solid surface surfaces reach for this sink when a customer wants an undermount look without switching to stone. The seamless method is documented and repeatable, and the equal bowl layout covers most residential kitchen layouts without requiring a custom spec. Designers specifying a kitchen with a Concrete or greige palette will find the color coordinates without forcing contrast. Homeowners renovating a laminate kitchen who want a sink that looks built-in — rather than dropped in — get that result here.
Can this sink be installed in a granite or quartz stone countertop?
The seamless installation method is documented for laminate and solid surface countertops. In granite, quartz stone, or similar hard surfaces, the sink can be installed as a conventional undermount, but the seamless-rim result requires laminate or solid surface fabrication.
Does the Q-350 include a drain, grid, or basket strainer?
The sink ships without a drain assembly, bottom grid, or basket strainer. Those components are sold separately and should be matched to this model specifically.
Where does the faucet mount if the sink has no faucet deck?
The faucet, soap dispenser, and any other accessories mount through holes drilled in the countertop behind the sink. This is standard practice for Q Series installations and keeps the sink body clean.
What minimum cabinet size does the Q-350 require?
Based on the sink's 32-3/8 inch overall width, a 33 inch or larger sink base cabinet is the typical fit. Confirm the actual cutout dimensions against your cabinet opening and countertop before cutting.
The Right Sink for Fabricators Who Want a Finished Look
When a kitchen renovation calls for an undermount sink that disappears into the counter rather than sitting below a visible rim, the Q-350 in Concrete delivers that result — in a double bowl layout that handles the full range of kitchen tasks, finished in a color that holds its own in today's neutral-driven design landscape.
