Powered by a 1HP compressor, it cools any standard bathtub from warm water down to 34°F in just 45-60 minutes, delivering consistent, repeatable cold water therapy at the exact temperature you dial in. The H3 sits beside your tub on rolling casters, with a patented bendable hose-arm that clips over the rim - nothing is plumbed in, nothing is permanent, and it rolls away when you're done.\n\u003c\/p\u003e\n\u003cp\u003e\nWinner of a CES Innovation Award and named to TIME Best Inventions, the H3 earned the highest Garage Gym Reviews score of any indoor cold plunge on their 2026 list. It's built for athletes, wellness enthusiasts, and anyone who wants the benefits of daily cold water immersion without redesigning their bathroom or hauling bags of ice.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e34°F Minimum Temperature:\u003c\/strong\u003e Cools your bathwater to true ice-bath cold without any ice - adjustable in 1°F increments down to 34°F.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1HP Compressor:\u003c\/strong\u003e Chills water at a rate of 20-30°F per hour, reaching cold plunge temperatures in 45-60 minutes for most standard tubs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero Plumbing Required:\u003c\/strong\u003e Plugs into a standard 110V\/60Hz household outlet - no electrician, no permits, no permanent installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatented Bendable Hose-Arm:\u003c\/strong\u003e Conceals both inlet and outlet hoses in a bend-and-stay insulated arm that clips over any tub rim in seconds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuya Smart App Control:\u003c\/strong\u003e iOS and Android compatible - set your target temp and schedule plunges remotely so your tub is ready when you are.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In Reusable Filtration:\u003c\/strong\u003e Integrated filter keeps water circulating and clean between sessions - no replacement cartridges, no chemicals required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Rolling Footprint (18.35\" W x 16.38\" D x 20.65\" H):\u003c\/strong\u003e Locking casters let you roll it beside the tub during use and stow it in a closet when you're done.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Operating Cost:\u003c\/strong\u003e Draws 4-6 amps while actively chilling (typically under 1 hour per day) - less than $10\/month for most users.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFCC \u0026amp; CE Certified:\u003c\/strong\u003e Meets recognized safety and electromagnetic standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Year Manufacturer Warranty Included:\u003c\/strong\u003e Extendable up to 4 total years with optional SureBright coverage at checkout.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eThis product requires additional shipping.

It's trusted by UFC fighters, former pro athletes, and everyday wellness enthusiasts who want a reliable, repeatable cold plunge practice built into their routine. The smart app scheduling means your bath can be chilled and waiting the moment you wake up or walk in from the gym - no prep, no ice runs, no guesswork. The reusable built-in filter keeps operating costs genuinely low, and the compact rolling design means it works just as well in an apartment as in a gym facility. If you're serious about recovery, focus, and feeling your best every day, the H3 is the most practical and capable way to bring cold therapy home.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eView Product Specs\u003c\/strong\u003e\u003c\/summary\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum Temperature\u003c\/th\u003e\n\u003ctd\u003e34°F (adjustable in 1°F increments, cooling only - no heating)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompressor\u003c\/th\u003e\n\u003ctd\u003e1HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCooling Rate\u003c\/th\u003e\n\u003ctd\u003e20-30°F per hour\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTime to Cold\u003c\/th\u003e\n\u003ctd\u003e45-60 minutes for most standard bathtubs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNoise Level\u003c\/th\u003e\n\u003ctd\u003e65-75 dB during operation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e110V \/ 60Hz standard outlet (220V \/ 50Hz available upon request)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAmperage Draw\u003c\/th\u003e\n\u003ctd\u003e4-6 amps while actively chilling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e18.35\" W x 16.38\" D x 20.65\" H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHose-Arm Length\u003c\/th\u003e\n\u003ctd\u003eStandard 3.5 ft (XL 5 ft available for +$299)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Tub Volume\u003c\/th\u003e\n\u003ctd\u003e30-110 gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApp Control\u003c\/th\u003e\n\u003ctd\u003eTuya smart app - iOS and Android\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFiltration\u003c\/th\u003e\n\u003ctd\u003eIntegrated reusable filter (no replacement cartridges required)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCertifications\u003c\/th\u003e\n\u003ctd\u003eFCC, CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e1-year manufacturer warranty included; extendable to 4 years with SureBright\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMobility\u003c\/th\u003e\n\u003ctd\u003eLocking casters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation\u003c\/th\u003e\n\u003ctd\u003eNo plumbing, no permits - plugs into standard wall outlet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAssembly Required\u003c\/th\u003e\n\u003ctd\u003eMinimal - hose-arm clicks into chiller, no fasteners or tools needed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShipping\u003c\/th\u003e\n\u003ctd\u003eShips freight; free U.S. shipping included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill the H3 fit my bathtub?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eIf your tub holds water and is between 30-110 gallons, the H3 will work. It's been tested on standard alcove tubs, freestanding soakers, clawfoot tubs, and acrylic spa tubs. The chiller doesn't go inside the tub - it sits beside it, and the patented bendable hose-arm clips over the rim to circulate water. Nothing is plumbed in or permanently attached.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow much does it cost to run the H3 each month?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eLess than $10\/month for most users. The H3 draws 4-6 amps while actively chilling, which is typically under an hour per plunge session. When idle, it draws near zero power. Running it daily costs less than a coffee subscription, and there are no ongoing filter cartridge costs since the built-in filter is reusable.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I have to drain the tub after every cold plunge?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eNo. Most H3 owners keep the same water for about a week and drain on the weekend. The built-in reusable filtration system keeps the water circulating and clean between sessions, so there's no need to drain and refill after every use. You can drain after every plunge if you prefer, but it's a choice - not a requirement.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the H3 require any plumbing or electrical work?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eNone at all. The H3 plugs into any standard 110V\/60Hz household outlet - the kind found in any bathroom. No electrician, no plumber, and no permits are needed. Setup takes just a few minutes: fill your tub, click the hose-arm into place over the rim, set your target temperature, and walk away. A 220V\/50Hz version is available upon request.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the H3 compare to buying bags of ice?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe H3 is more consistent, more convenient, and cheaper over time. Ice baths are inconsistent - the temperature spikes when you get in and warms unevenly as ice melts. Buying ice in bulk gets expensive quickly, and hauling bags is a daily chore. The H3 delivers the exact temperature you set every single time, lets you schedule sessions from your phone, and costs less than $10\/month to run - no prep, no cleanup, no ice runs.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I control the H3 from my phone?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes. The H3 uses the Tuya smart app, available on both iOS and Android. You can set your target temperature and schedule plunge sessions remotely, so your tub can be chilled and ready before you wake up or right when you get home from the gym. You can also adjust settings directly on the unit's touchscreen.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat warranty comes with the H3?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eEvery H3 comes with a 1-year manufacturer warranty included at no extra cost.
