The Cold Plunge Pro is built for longevity, using industrial-grade stainless steel to maintain water temp and protect the tub from the elements (built-in caster wheels allow you to move it from indoors to outdoors or vice versa). Our testers did note that the metal wasn’t exactly comfortable seating, and the 6’5″ length is deceiving: Because of the integrated chiller, the interior is only about four feet long and our tester couldn’t fully extend his legs. On the plus side, you don’t have to clean it when you’re done—the three-step filtration system ensures clean, clear water every time.
Misery loves company in AquaVoss Model 2, a premium model that allows multiple users to partake in post-workout contrast therapy.
Our Tester’s Take
Alternating between hot and cold tubs—causing your blood vessels to expand and then narrow, a protocol that’s been linked to improved circulation and reduced soreness—generally requires two tubs. Not so with the AquaVoss Model 2, which combines a two-person cold plunge with a four-person hot tub so you’re getting the most bang for your buck (and the significant square footage).
The cold plunge features an acclimation seat to help you ease into the icy depths, powered by a robust 1-horsepower chiller for precise temperature control. When it’s time to warm up, sink into ergonomic seating while 24 high-velocity hydrotherapeutic massage jets work their magic on tired muscles. Crafted from a proprietary exterior paneling and lined with heavy-duty spray foam insulation, the AquaVoss Model 2 expertly maintains its temperatures, regardless of the elements outside.
The energy efficiency and quiet operation are standout features, too; the hot tub side has a circulation pump that runs the water through a filter and ozone cleaning system every three to four hours while the cold plunge side has a three-step system to keep it clean no matter who’s cycling through. It’s no doubt a splurge, but the price is a deal if you consider what it would cost to buy two separate high-tech tubs for the same purpose.
The NordicWave Viking Gen 2 cools down to 36°F and heats up to 104°F, offering two types of therapy in a space-saving footprint that would fit in almost any home.
Our Tester’s Take
The NordicWave Viking Gen 2 looks basic, with its barrel shape and plastic exterior, but it’s actually a two-in-one tub that makes hot and cold therapy more accessible to those with less space for at-home recovery tools. When empty, the tub is just 60 pounds—super easy to move around to best suit your square footage.
With a temperature range from 36°F to 104°F, the NordicWave Viking Gen 2 lets you seamlessly switch between ice-cold immersion for muscle recovery and a soothing hot soak for relaxation (although it will take a significant amount of time to heat or cool the tub). The quiet, energy-efficient filtration system ensures clean water every time, while the easy-to-use digital control panel gives you complete command over your experience.
You’ll want to set up this vertical tub outside so it can drain properly, but it’s designed for year-round use. The updated chiller doesn’t require winterization and has an increased flow rate for faster water circulation and temperature adjustments. Plus, it’s built with a UV-resistant shell and two inches of foam-insulated walls that help lower energy costs while maintaining your ideal temperatures, even in the most extreme weather.
With a sleek design and simple-to-use controls, the Hydragun Supertub Cold Plunge is the perfect entry point into cold plunge therapy for those who want results without the premium price.
Our Tester’s Take
The Hydragun Supertub Cold Plunge isn’t as cheap as, say, your bathtub and a few bags of ice, but with cold plunge costs stretching into five figures, this model rings up at a fraction of the price of its high-end competitors. It’s packed with features that rival more expensive tubs, but the inflatable design is lightweight (just 21 pounds without water), compact, and easy to set up in under 15 minutes, according to our testers.
