The bathroom counter revolution happened quietly—one household at a time replacing string floss with water flossers. Among these dental innovations, the Waterpik Ultra stands as a veteran performer. At $69.99 from Kohl’s, this countertop water flosser promises professional-grade oral care at home.
I’ve analyzed everything from its 10 pressure settings to its specialized tips to help you decide if this is the dental upgrade your bathroom needs. With claims of removing up to 99.9% of plaque from treated areas, the Ultra model deserves a closer look—especially considering its longstanding popularity in a market flooded with newer competitors.
What’s in the Box: Waterpik Ultra Components & Specifications
The Waterpik Ultra countertop water flosser arrives with everything needed to transform your oral hygiene routine. Opening the box reveals the main unit, a 22-ounce covered reservoir, and a comprehensive set of six specialized tips designed for different oral care needs. This collection includes two Classic Jet tips for everyday use, an Orthodontic tip, a Plaque Seeker tip, a Pik Pocket tip, and a Toothbrush tip—providing solutions for virtually every dental situation.
Technical specifications of the Ultra (models WP-100, WP-112, WP-113, WP-115, WP-117, and WP-118) highlight its versatility. The 10 adjustable pressure settings range from a gentle 10 PSI to a powerful 100 PSI, accommodating users with sensitive gums and those requiring more intense cleaning. The sizeable 22-ounce reservoir provides over 90 seconds of flossing time even at the highest pressure setting—sufficient for a thorough cleaning without refilling.
Regarding counter space requirements, the Waterpik Ultra measures 9.9″ high, 5.6″ wide, and 5.3″ deep. While not the most compact water flosser on the market, its footprint remains reasonable for most bathroom counters. The unit weighs approximately 1.5 pounds when empty, making it substantial enough to stay put during use but light enough to move as needed.
The device operates on standard North American power (120 VAC/60 Hz) with a 4.5-foot power cord—adequate for reaching nearby outlets but potentially limiting depending on your bathroom layout. A standout design feature is the 360-degree rotating tip, which significantly improves maneuverability for reaching difficult areas in the mouth.
Performance Analysis: How the Waterpik Ultra Actually Works
At the heart of the Waterpik Ultra’s performance is its pulsation technology, delivering approximately 1,400 water pulses per minute. This rapid pulsation creates a dynamic cleaning action that dislodges food particles and bacteria from areas traditional floss struggles to reach. The pulsed water flow, rather than a continuous stream, enhances the cleaning effectiveness while reducing water usage.
The 90+ second operational time per reservoir fill (at maximum pressure) provides ample duration for a complete mouth cleaning. Most users report that a single fill suffices for their entire flossing routine, eliminating the inconvenience of mid-session refills.
Regarding Waterpik’s claim of being “50% more effective than string floss,” clinical studies support this assertion, particularly for removing plaque from difficult-to-reach areas. The pulsating water flow can access areas between teeth and below the gumline that string floss might miss, especially around dental work or in periodontal pockets.
Noise levels vary considerably across pressure settings. At lower pressures (1-4), the Ultra operates at an acceptable volume. However, at higher settings (7-10), noise becomes more pronounced—potentially disruptive in shared living spaces or during late-night use.
Water flow consistency remains reliable across the pressure range, with minimal fluctuation once a setting is selected. The gradual progression between pressure levels allows users to find their optimal comfort zone.
Compared to newer Waterpik models, the Ultra lacks certain features like preset timers, massage modes, or LED displays. However, its fundamental technology and cleaning effectiveness remain on par with more recent offerings.
Specialized Tips & Their Applications
Classic Jet Tips
The two included Classic Jet tips serve as the standard workhorses for everyday use. These tips deliver a concentrated stream of water for general cleaning between teeth and along the gumline. Ideal for routine maintenance, they remove food particles and plaque from areas that toothbrushes can’t reach. Users with healthy gums and no specialized dental work may find these tips sufficient for their needs.
Orthodontic Tip
The Orthodontic tip features a tapered brush end specifically designed for cleaning around braces, wires, and brackets. The combination of bristles and water pulsation cleans both the orthodontic hardware and the surrounding teeth, significantly reducing the risk of decalcification and gum inflammation during orthodontic treatment. This tip proves invaluable for both teenagers and adults with braces or retainers.
Plaque Seeker Tip
Equipped with small bristles surrounding the water outlet, the Plaque Seeker tip targets areas around dental implants, crowns, bridges, and veneers. The bristles help disrupt biofilm while the water flushes away debris from these prosthetic surfaces and the vulnerable margins where they meet natural tissue. This specialized approach helps protect significant dental investments from failure due to peri-implantitis or recurrent decay.
Pik Pocket Tip
The Pik Pocket tip delivers water below the gumline into periodontal pockets—spaces between teeth and gums that deepen with gum disease. Its soft, rubber tip and gentler water delivery system specifically target bacteria in these pockets, areas completely inaccessible to traditional flossing. For users with diagnosed periodontal disease, this tip can be an essential part of managing their condition between professional cleanings.
Toothbrush Tip
Combining brushing and flossing actions, the Toothbrush tip allows simultaneous mechanical cleaning and water pulsation. This dual-action approach can increase efficiency for those with time constraints. The tip works particularly well for cleaning along the gumline and reaching the surfaces of back molars.
For optimal results, each tip should be replaced every 3-6 months depending on usage frequency. Compatible replacement tips are available at Kohl’s and other retailers carrying Waterpik products.
Kohl’s Pricing, Warranty & Value Proposition
Kohl’s offers the Waterpik Ultra for $69.99, positioning it in the mid-range of water flosser options. This price point remains competitive compared to other retailers, who typically price the Ultra between $65-$80. The consistent Kohl’s pricing structure provides transparency when budgeting for this oral health investment.
Kohl’s customers gain additional value through the store’s loyalty programs. Purchases often qualify for Kohl’s Cash promotions, effectively reducing the net cost during promotional periods. Furthermore, Kohl’s Card members may access additional discounts, potentially bringing the effective price below competitors’ offerings.
The manufacturer’s 3-year limited warranty covers defects in materials and workmanship under normal household use. This warranty period exceeds many competing brands’ coverage, reflecting Waterpik’s confidence in their product’s durability. The warranty specifically covers electrical components, pump mechanisms, and reservoir integrity—though it excludes replacement tips and damage from improper use.
From a cost-benefit perspective, the Waterpik Ultra presents compelling value. Professional dental cleanings typically cost $75-$200 per visit without insurance. While the Ultra doesn’t replace professional care, its effective plaque removal can potentially reduce complications and expensive treatments between dental visits.
Compared to budget water flossers ($30-$50), the Ultra offers superior durability, more consistent water pressure, and a wider range of specialized tips. Against premium models ($100+), it maintains core functionality while forgoing aesthetic refinements and supplementary features like Bluetooth connectivity or LED displays.
Daily Use Experience & Maintenance Tips
First-time setup of the Waterpik Ultra is straightforward: attach your chosen tip, fill the reservoir with lukewarm water, and select a pressure setting. New users should start at the lowest pressure setting (1 or 2) and gradually increase as comfort develops. Most users report a 3-5 day adaptation period before achieving comfortable and effective technique.
For maximum effectiveness, hold the tip at a 90-degree angle to the tooth surface, slightly away from the gums. Focus the stream between teeth and along the gumline, pausing briefly at each space. Close lips slightly to prevent splashing while allowing water to drain naturally into the sink. A methodical approach—cleaning all quadrants of the mouth systematically—ensures thorough coverage.
Daily maintenance involves simple steps: empty excess water from the reservoir after use, and leave the unit partially open to air-dry, reducing mold or mildew risk. Weekly maintenance should include running a reservoir of diluted white vinegar (1:1 ratio with water) through the unit to prevent mineral buildup, particularly important in hard water areas.
Common issues include reservoir leakage and pressure inconsistencies. For leaks around the reservoir stopper, pressing it firmly inward before filling often reestablishes the seal. Pressure fluctuations typically indicate mineral buildup in the internal components—resolved through the vinegar cleaning process described above.
The Waterpik Ultra’s expected lifespan ranges from 3-5 years with proper maintenance, though many users report longer service periods. Storing the unit in a cabinet when not in use can protect it from bathroom humidity and extend its operational life.
Smart Shopping Decision: Making the Right Choice
The Waterpik Ultra Water Flosser represents a solid middle-ground in dental care—more effective than string floss but more affordable than premium water flossers with extra features. For most households, its combination of proven technology, versatile tips, and reasonable price point makes it a worthy investment in oral health. The 3-year warranty provides peace of mind, while Kohl’s occasional promotions can make it an even better value. Consider your specific dental needs, counter space, and whether you need the latest features before purchasing. Your gums might thank you for making the switch—even if your bathroom counter gets slightly more crowded.
