A 30-Inch Single Bowl Undermount For Uninterrupted Workspace
The Karran Profile PU25N is an 18-gauge stainless steel undermount kitchen sink with an extra-large single bowl measuring 30 by 18 by 9 inches. Designed to mount beneath the countertop, it gives kitchens a clean sightline and a wide, open basin that handles oversized cookware, sheet pans, and high-volume use without a divider in the way. It ships in a case of 40, making it a practical stocking choice for cabinet shops, contractors, and kitchen installers fitting multiple units.
Key Features
• 18-gauge stainless steel construction delivers a balance of durability and workable weight for professional installation.
• Extra-large single bowl offers an unobstructed 30 by 18 by 9 inch interior that accommodates full sheet pans and large stock pots flat on the bottom.
• Undermount design mounts beneath the countertop so the counter surface wipes clean to the edge without a rim catching debris.
• Profile Series construction pairs a brushed satin finish with a straightforward profile suited to a wide range of kitchen styles.
• Case quantity of 40 supports shops and contractors installing sinks across multiple kitchens from a single order.
Where the Extra-Large Bowl Earns Its Keep
A 30-inch single bowl is the right call when the cook's workflow demands one deep, uninterrupted work area. There is no center divider to work around when soaking a large roasting pan, bathing a cutting board, or filling a tall stockpot. The 9-inch depth keeps water contained during active use and provides clearance for a pull-down or high-arc faucet to reach the bowl bottom without splashing. This configuration is also common in butler's pantries, open-plan islands, and secondary prep stations where a single dedicated basin is more useful than split capacity.
18-Gauge Stainless and the Brushed Satin Finish
The Profile Series uses 18-gauge stainless steel throughout the bowl, a gauge that provides solid everyday performance at a practical price point for volume projects. The brushed satin interior finish reduces the visibility of fine surface marks that accumulate with normal kitchen use, keeping the bowl looking presentable between cleanings. Because the faucet mounts through the countertop on an undermount installation — there is no faucet deck on this sink — the countertop material and fabrication method determine where the faucet and any accessories are located. Stainless steel is for indoor kitchen use; match the countertop material to the fabricator's specifications for undermount installs.
The Right Fit for Volume Kitchen Projects
Cabinet shops spec'ing a standard single-bowl undermount across a production run of kitchens benefit from the consistency of ordering the same SKU in quantity. Contractors staging multiple kitchen installs on a job site can pull from a case stock rather than managing individual orders. Homeowners and designers specifying a single unit get a sink that installs with standard undermount methods into stone, engineered stone, or solid surface countertops. The Profile Series occupies a practical middle position: more bowl than a 24- or 27-inch single, without the footprint of a 33-inch double. Confirm the minimum cabinet opening with the base cabinet specification before ordering.
Frequently Asked Questions
Does this sink include a drain, grid, or mounting clips?
This SKU is the bare sink. Basket strainers, bottom grids, and mounting clips are sold separately. Confirm the drain opening size and clip system with your countertop fabricator before purchasing accessories.
Where does the faucet mount on an undermount installation?
Because this is a no-deck undermount sink, the faucet mounts through the countertop itself, not through the sink. Your fabricator will drill the faucet holes in the counter based on your faucet's spacing and your countertop material.
What countertop materials work with this undermount sink?
Standard undermount installation is suited to stone, engineered quartz, granite, and solid surface countertops where the fabricator can finish the cutout edge and secure the sink from below. Laminate countertops are not typically recommended for undermount installs; a top mount Profile model is the better route for laminate applications.
What is the minimum base cabinet size for this sink?
A 30-inch overall-width sink typically requires at minimum a 33-inch sink base cabinet to allow for wall clearances and plumbing access, but confirm the actual cutout dimensions against your cabinet specification before cutting. The manufacturer's cutout template or DXF file is the definitive reference.
Is ordering by the case required, or can a single sink be purchased?
This listing is priced and sold as a case of 40 units. Review the page's quantity selector and pricing tiers if your project requires fewer units.
One Sink That Keeps Production Moving
Whether it is a single kitchen renovation or a full production run of cabinetry, the Karran Profile PU25N delivers a consistent, professional undermount result. The extra-large bowl handles real kitchen work, the 18-gauge build holds up to a busy install schedule, and the case quantity keeps project timelines from stalling over a missing part.
