Addictive Cold Plunge Tub!

Can’t Believe It’s As Good As The Hype

Plunge Life!

- GCGreg C.Verified BuyerRated 5 out of 5 stars22 hours agoTwo months in and loving the experience!
The company and founder himself have helped us at every turn as we took our cold plunge voyage. The tub is great and the chiller works well. We’ve had a couple of learning curve items around chemicals etc, but we’re doing great. Highly recommend the tub and wouldn’t hesitate to become part of the Inergize family. Thank you
- MMikeVerified ReviewerRated 5 out of 5 stars2 months agoInergize Fan
Bought mine 10 months ago. Took a bit to get to know how to maintain my tub, but I've got the routine down now. I've looked at other tubs, but love how small this is, perfect size for me (I'm 5'10"). Customer service is very helpful and responsive. Since I live in hot Arizona, I use this every single night, right after I take a shower, so as to keep the tub clean. Too many benefits to list out, very happy with this purchase, highly recommend it!
