Some of our commercial partners
"Lots of other brands don’t actually understand water, hydraulics, filtration, or heating/cooling…That’s what impressed me about ReGen. I pick a product for my clients that I trust will work… I don’t care about name brands or any of that—I care about not getting a call on Sunday night at 8pm because JJ's cold plunge was 87°."
I’ve had my tub for almost a year now and couldn’t imagine being without one. The quality is top-notch, service is outstanding and the tub has been a game changer for my wife and I. I would highly recommend anyone thinking about purchasing one, go with ReGen.
I had the brand “Plunge” and the brand MODTUB as well as used many other brands in a sports, spa and wellness setting and ReGen is the best. It’s the easiest to connect, clean, most comfortable position and the arctic blast button is the most advanced for cold therapy.
I'VE HAD MY 73" TUB FOR A LITTLE OVER 2 MONTHS NOW. COULD NOT BE HAPPIER. GREAT QUALITY, THE TEMPERATURE STAYS VERY CONSISTENT. I'M CURRENTLY AT 45 DEGREES PLUNGING DAILY. VERY SIMPLE TO DRAIN THE FIRST TIME AND CHANGE THE FILTER. I HIGHLY RECOMMEND THIS TUB IF YOU'RE IN THE MARKET!
ReGen’s cold tub is an amazing addition to anyone’s home looking to ramp up their lifestyle. Not only does the effects of cold plunging speak for itself, but the sleek and simplistic design make Regen the clear go to compared to the other brands. The team was so helpful in the installation walkthrough and I couldn’t recommend it enough to anyone who wants to boost their health and recovery journey.

Our Mission
To build better wellness tools — and better daily routines — through products that are engineered to last, accessible to use, and trusted by high-performing people everywhere. We believe the best results come from consistency, not complexity. Our mission is to make that consistency easier, more enjoyable, and built to withstand real-world use.
Why We Exist
Because people deserve wellness products that are actually built well. Cheap parts, overhyped marketing, and unreliable equipment have become the norm in the recovery industry. We started ReGen to do the opposite — to build products that you can count on day after day, in any climate, with support from a real human when you need it.
We Are Unique
ReGen is engineered differently — and supported differently. We build our cold plunges with commercial-grade components, high-flow systems, oversized filtration, and Arizona-tested insulation. And unlike big-box brands, we stay hands-on with every customer, from purchase to setup to long-term maintenance. Quality equipment paired with real support is what makes ReGen stand out.
What makes us different?
- Built for extreme environments. Arizona summers to Midwest winters
- Premium materials — stainless steel, commercial-grade chillers, high-flow systems
- Rooted in science — every feature is designed to support real physiological recovery
- Plug-and-plunge ready — no plumbing, no guesswork, just performance
- Human-first support — we handle every service and support ticket in-house
We don’t just build products — we build trust, results, and a recovery experience you can rely on for years.
