16-Gauge Construction and Uninterrupted Basin Space
The Karran Profile Series PU55N is a 16-gauge stainless steel undermount sink designed for kitchens where a single large bowl handles everything from sheet pans to oversized stockpots. Its 30 by 18 by 9 inch bowl mounts beneath the countertop for a clean, rim-free surface that wipes down in one pass.
Key Features
• 16-gauge stainless steel construction delivers a noticeably thicker, more rigid bowl than standard 18-gauge sinks, reducing flex and deadening sound under running water.
• Undermount installation places the rim beneath the countertop so the counter surface is uninterrupted and easy to keep clean.
• Extra-large 30 x 18 x 9 inch single bowl accommodates full sheet pans, large stockpots, and oversized baking dishes without a divider in the way.
• Profile Series fit is engineered for a conventional undermount install in quartz, granite, and solid surface countertops, compatible with standard sink-base cabinetry.
• Brushed satin stainless finish diffuses water spots and surface marks that would show on a polished bowl.
Where This Sink Delivers
A 30-inch single bowl is one of the most practical configurations a kitchen can have. Without a center divider, the full basin depth is available for soaking large roasting pans, hand-washing oversized items, or staging work during heavy prep. The 9-inch depth keeps tall pots fully submerged and reduces splashback during rinsing. This is the configuration kitchen designers reach for when clients cook regularly and need space that actually matches how they use the sink.
Cabinet shops and contractors specifying kitchen packages will find this sink straightforward to coordinate: the undermount footprint fits a standard sink base, faucet drillings go through the countertop rather than a deck, and the Profile Series produces a consistent finished look across project lines.
Gauge, Finish, and Build Quality
The step from 18 gauge to 16 gauge makes a tangible difference in daily use. Thicker walls and a more rigid bowl floor reduce the drum-like resonance common in lighter sinks and stand up better to the impact of heavy cookware. The brushed satin finish is applied uniformly across the interior and exterior, softening the appearance of fine scratches and water mineral deposits over time. This is a working sink built to hold up in kitchens that see real volume, not a light-duty fixture finished to look good in a showroom photo.
The Right Fit for This Sink
This sink is well matched to homeowners remodeling a primary kitchen who want capacity over convenience features, designers specifying a hardworking main sink for an active household, and cabinet shops building kitchen packages where a dependable undermount bowl is part of the spec. Because the faucet mounts through the countertop rather than a sink deck, it pairs cleanly with stone, engineered quartz, and solid surface tops. For installations in laminate countertops or where a seamless rim finish is required, the Karran Edge or Q Series is the right path instead.
FAQ
Does this sink include a drain, grid, or basket strainer?
The PU55N ships as a bare sink. Drains, basket strainers, and bottom grids are sold separately. If you want a matched bundle with strainers and a grid included, look for the -PK1 version of this model.
Can this sink be installed in a laminate countertop?
This Profile Series undermount sink is designed for quartz, granite, and solid surface installations. For laminate countertops, Karran's Edge or Q Series sinks are specifically engineered for that install method.
Where does the faucet mount on this sink?
There is no faucet deck on this model. The faucet, soap dispenser, and any accessories mount through the countertop behind the bowl.
What countertop cutout method does this sink require?
Use the actual sink as your template before cutting. A DXF file may be available from Karran for CNC cutouts. Always confirm the actual sink dimensions against your countertop opening before the cut is made.
Is this sink sold individually or in the box quantity?
The listing reflects the box quantity of 40 units, which is the case pack for volume ordering. Individual units are available — check the quantity selector for your order size.
Built for Kitchens That Work Hard
The PU55N gives active kitchens the basin space and build quality that lighter sinks cannot match: a full 30-inch span, 16-gauge walls, and a clean undermount profile that keeps the counter looking finished for the life of the installation.
