Built different. On purpose.
Take your health routine to the next level with the TheraFrost portable cold plunge system. This advanced system allows you to experience the benefits of cold water immersion therapy in the comfort of your own home.
The TheraFrost chills water down to 37°F and maintains that temperature for hours, so you can take multiple cold plunges per session. It uses triple-patented Structured Water technology to restructure the water, maximizing its positive effects. The large capacity inflatable tub holds over 100 gallons, providing plenty of space to immerse your entire body.
This all-weather, digital programmable chiller is made with high-grade rubber for durability. It features an integrated ozone purification system that bursts ozone into the water for purity. Use the Apple iOS and Android apps to control temperatures and ozone levels remotely.
Portable and easy to use, the TheraFrost makes cold water immersion accessible anytime. Experience reduced inflammation, improved circulation, and boosted immunity. Take the plunge into better health with the most advanced portable cold plunge system on the market.

FAQ
How long does delivery take?+
2–3 weeks from order. Cold plunges and saunas ship curbside LTL freight direct from the manufacturer; you'll get tracking and a scheduled delivery window 24-48 hours before drop-off. Chillers and small items ship parcel.
Is shipping really free?+
Free curbside freight on cold plunges and saunas to the lower 48. The carrier delivers to your curb or driveway; you handle final placement and quick DIY setup (we text you through it), or we can refer a local installer. Chillers and accessories ship parcel.
What's the warranty?+
It depends on the brand — every product carries the manufacturer's own warranty, which we pass through and help you file. Dundalk cedar cold plunges carry up to a 5-year residential limited warranty on the tub (parts only); the bundled chiller is typically 1 year. Golden Designs and Maxxus saunas run 5 years on heating elements and electronics, 1 year on the wood. Most other brands are 1–2 years. You generally cover shipping to return a defective part. Full terms are on this product's page — text us and we'll pull them up.
What if something breaks?+
Text us a photo. We diagnose it, file the manufacturer warranty claim for you, and expedite the maker's part. Most issues resolved fast.
Can I return it?+
30-day try-it-cold guarantee on uninstalled products. After 30 days, warranty applies.
