Karran Profile Sink For an Uninterrupted, Large-Capacity Wash Station
The Karran PU55-PK1 is a 16 gauge stainless steel single bowl undermount kitchen sink designed for installations where maximum unobstructed workspace matters most. Part of the Profile Series, it arrives as a complete kit with the accessories needed to put it straight to work.
Key Features
• 16 gauge stainless steel construction delivers a noticeably thicker, more rigid bowl than standard 18 gauge sinks.
• Large single bowl configuration provides an uninterrupted interior that accommodates full sheet pans and large cookware flat on the grid.
• Undermount installation keeps the countertop surface clean and uninterrupted, with no rim to trap food or debris.
• Included basket strainer and bottom grid protect the bowl floor and connect directly to standard kitchen drain plumbing.
• Luster Pro sink care oil ships in the kit to condition and protect the stainless finish from day one.
• Profile Series design features a classic bowl profile suited to both traditional and contemporary kitchen layouts.
Where This Sink Fits the Work
A single bowl this size earns its place in kitchens that see real daily volume. Without a divider breaking up the interior, there is room to soak a roasting pan, rinse a full colander, or stack dishes without working around a center wall. For cabinet shops and contractors specifying for clients who cook seriously, that unbroken depth changes how the sink actually gets used. Island installations benefit especially, since the undermount profile leaves the countertop edge clean on all sides. This sink also works well as the primary wash station in a kitchen that relies on a separate prep or bar sink elsewhere in the run.
Construction and Finish
Gauge is the primary quality signal in stainless kitchen sinks, and 16 gauge steel is meaningfully thicker than the 18 gauge material common at this price point. The heavier gauge resists flex underfoot and deadens sound more effectively than thinner steel. The Profile Series carries a brushed satin finish that diffuses light evenly and shows fingerprints less aggressively than a mirror polish. The stainless material is corrosion resistant under normal kitchen conditions. The included bottom grid keeps the bowl floor protected from daily wear, and the basket strainer fits the standard drain opening so plumbing connections are straightforward.
Right For This Project
This kit is a natural fit for remodelers and contractors working in quartz, granite, or solid surface countertops where an undermount profile is specified. Cabinet shops staging a full kitchen install appreciate having the strainer and grid resolved in a single order rather than sourcing them separately. Homeowners renovating a primary kitchen who want a single large bowl and do not want to manage multiple accessory purchases will find the kit format reduces the sourcing work on installation day. The 16 gauge spec makes this a straightforward upgrade from builder-grade 18 gauge sinks for clients who plan to stay in the home long term.
Frequently Asked Questions
Does this sink include a template for cutting the countertop?
No. A paper cutout template is not included with the PU55-PK1. Fabricators working in stone or solid surface should use the actual sink as the reference, or request a DXF file for CNC cutting. Verify the countertop cutout against the sink before making the final cut.
What countertop materials work with an undermount installation?
Undermount sinks are compatible with countertop materials that can support the sink at the rim edge, including granite, quartz composite, and solid surface. Laminate countertops are not suited to standard undermount installation; for a laminate-compatible stainless option, see the Karran Edge seamless series.
Is a faucet included in this kit?
No faucet is included. Because this sink has no faucet deck, the faucet mounts through the countertop. Select a faucet with a mounting footprint that matches the hole drillings planned for your countertop.
What drain opening size does the bowl use?
The bowl uses a standard 3-1/2 inch kitchen drain opening. The included basket strainer is sized to match, and standard kitchen drain plumbing connects directly.
What is the minimum cabinet size for this sink?
Minimum cabinet size is not published in the available source data for this model. Given the 30 inch overall length, a 33 inch or 36 inch sink base is the typical fit, but confirm against the actual sink dimensions and your cabinet opening before ordering.
A Complete Kit, Ready for the Counter
The PU55-PK1 brings together a 16 gauge Profile Series bowl, a bottom grid, a basket strainer, and Luster Pro care oil so installation day moves without a last-minute trip for accessories. For kitchen projects where workspace and durability are the brief, this sink is ready to deliver both.
