Warm & Hot Soaking Therapy Powered by Patented Oxygen Nanobubble Technology
Detox. Repair. Reset. Energize.
Description
ReGen O2™ — Oxygen-Infused Soaking
ReGen O2 isn’t a hot tub.
It’s oxygen delivery through water.
Using patented oxygen nanobubble technology, ReGen O2 infuses warm or hot water with billions of ultra-fine oxygen bubbles that stay suspended and interact directly with your skin during your soak.
The result: a deeper, more oxygen-rich experience that supports recovery, circulation, detoxification, and overall vitality.
No jets. No surface bubbles. No wasted oxygen.
Just sustained exposure, session after session.
Designed for daily use.
Built for real recovery.
Detox. Repair. Reset. Energize.
Hyper Dissolved Oxygen Technology
Powered by patented Hyper Dissolved Oxygen technology, ReGen O2 saturates the water with billions of oxygen-rich nanobubbles—designed to deliver a deeper, more restorative soak that supports recovery, circulation, and cellular repair.

What Makes ReGen O2 Different
ReGen O2 works at the cellular level.
The water is infused with hyper-dissolved oxygen, allowing oxygen to interact with the dermis and epidermis during your soak—supporting circulation, recovery, detoxification, and overall vitality.
This is the same oxygen nanobubble technology used in advanced therapeutic and recovery applications—but engineered for daily, at-home use.
Patented Oxygen Nanobubble Technology
ReGen O2 uses a patented ultrafine bubble process to create oxygen bubbles smaller than 100 nanometers.
Why that matters:
- Ultra-fine bubbles stay suspended in water instead of rising and popping
- Slow oxygen release creates prolonged exposure during your soak
- High surface area increases biological interaction
- Stable negative surface charge improves effectiveness and longevity in water
Unlike standard aeration or jets, this technology delivers true hyper-dissolved oxygen, not surface-level bubbles.
Users consistently report:
- Feeling deeply relaxed yet energized
- Noticeably improved sleep the night after soaking
- Faster recovery after training or physical stress
- Improved skin tone and warmth
- Reduced stiffness and inflammation
Many report benefits after just one session, with cumulative effects over time
Oxygen is fundamental to recovery.
Low oxygen levels (hypoxia) are associated with:
- Slower tissue repair
- Increased inflammation
- Poor circulation
- Fatigue and brain fog
By increasing oxygen availability during soaking, ReGen O2 supports:
- Improved circulation and cardiovascular efficiency
- Cellular repair and regeneration
- Detoxification and metabolic efficiency
- Immune system support
- Cognitive clarity and mental reset

Trusted by Those Who Use It
"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.
Cold plunging creates stress.
