Most people focus on water temperature, but here’s the truth: a low-flow tub will feel warmer than it reads. That’s because your body creates a thermal pocket in still water.

ReGen’s high-flow system keeps water moving over every part of your body, disrupting that warm layer and delivering full-body cold immersion the entire time you’re in.

When shopping for a cold plunge, you want more than just cold water — you want reliability, power, and results.

1. Circulation – Flow rate is king. More movement = more effective therapy.
2. Chiller Power – Can it actually hit and hold 36°F?
3. Cleanliness – Ozone + filtration keep your water clean without chemicals.
4. Construction – Commercial-grade materials, built to last.
5. Customer Experience – Real support. No runaround.

Cold plunging isn’t a trend — it’s a proven tool used by experts to enhance physical and mental health.

Backed by 20+ studies, cold water immersion helps with:

🧠 Boosted dopamine & mood regulation
🔥 Reduced inflammation and pain
💤 Improved sleep quality
💪 Increased mental resilience and stress tolerance
🦠 Strengthened immune response
⚡ Faster post-workout recovery
