Stainless Steel Pop-Up Drain Built for Overflow Bowls
The Karran PUOF25SS is a pop-up drain designed specifically for vanity bowls with an integral overflow. Its Stainless Steel finish makes it a natural pairing for contemporary bathroom installations where the drain needs to hold its own against other metal finishes in the space.
Key Features
• Overflow-compatible design routes rising water through the bowl's integral overflow channel, so this drain is matched to bowls that have an overflow aperture.
• Stainless Steel finish coordinates cleanly with brushed and satin metal hardware throughout the bathroom.
• Pop-up stopper mechanism opens and seats at the bowl bottom without a separate lift rod in every configuration — keeping the vanity deck uncluttered.
• Lavatory drain sizing fits the standard 1-3/4 inch vanity drain opening common to bathroom bowls in this catalog.
• Karran engineering pairs directly with Karran's vanity bowl lineup, including quartz, acrylic, vitreous china, and solid surface bowls that include an overflow.
Where This Drain Fits the Job
Pop-up drains are a detail that rewards getting right. A bathroom vanity sees daily contact — water, soap, toothpaste — and the drain is one of the most frequently touched fixtures at the sink. The PUOF25SS handles that duty in vanity and powder room settings where the bowl already has an integral overflow built into its wall. The overflow channel is the path rising water takes before it spills over the rim; this drain is built to work with that system rather than ignore it. Pair it on a bathroom remodel where existing plumbing is being refreshed alongside a new vanity bowl, or specify it in new construction where the bowl and drain are selected together from the start.
Finish and Construction
Stainless Steel is a versatile finish call in a bathroom. It reads as neither warm nor cool in isolation, which means it doesn't fight brushed nickel, chrome, or even matte metal hardware the way a high-contrast finish might. For fabricators and contractors finishing out a vanity, that flexibility reduces the risk of a finish mismatch when the faucet and accessories come from different runs or slightly different sources. The drain body is built to Karran's standard for its pop-up drain line — the same product family as the without-overflow PU25, just engineered for the overflow bowl configuration.
Who Specifies This Drain
Cabinet shops completing vanity installations will reach for the PUOF25SS when the bowl on the job has an overflow. Designers specifying a full Karran vanity package — bowl, faucet, and drain — can close out the drain line item with this SKU when Stainless Steel coordinates with the rest of the hardware. Homeowners replacing a worn drain on an existing overflow bowl get a straightforward swap that keeps the finish consistent with common bathroom fixture finishes. The one rule that governs the choice: the bowl must have an integral overflow. If it does not, the without-overflow version is the correct pick.
Frequently Asked Questions
What is the difference between PUOF25SS and PU25SS?
The PUOF25 is the with-overflow version; it routes water through the bowl's overflow channel. The PU25 is the without-overflow version and is for bowls that have no overflow aperture. The two are not interchangeable — the bowl's construction determines which drain to order.
How do I know if my vanity bowl has an overflow?
An overflow bowl has a small opening or slot near the top interior wall of the basin. If you don't see one, the bowl has no overflow and the PU25 without-overflow drain is the correct match.
Does this drain fit any brand of vanity bowl, or only Karran?
The drain is sized for the standard 1-3/4 inch lavatory drain opening. It is engineered and published as part of Karran's accessory line, so compatibility with non-Karran bowls should be verified against the bowl manufacturer's stated drain opening size and overflow configuration before ordering.
Is a separate drain assembly or tailpiece included?
Component contents are listed in the product's spec block. Review what ships with this SKU there before planning the rough-in, and order any additional fittings separately if needed.
The Right Drain, Matched to the Bowl
Getting the overflow pairing correct means the vanity functions exactly as it should from day one — no guesswork, no callbacks. The PUOF25SS in Stainless Steel closes out the drain spec cleanly for overflow-equipped bowls where a finish that works across a wide range of bathroom hardware is the right call.
