Everyone should have one

The Cold Stoic is a 10/10. I use It every morning and love It. The tank is very cool looking and matches my outdoor furniture plus It requires very little maintenance. It stays cool and clean all the time. I couldn’t recommend It highly enough.

Love it!

Nice products. Beautiful results. Thank you.

Changes the way you perceive live!

I start following the Wim Hof method and got interested in the cold plunges. But filling the tub with 8 bags of ice once or twice a week takes away all the incentive to take the cold plunge. Besides it is a lot of water that goes away in the drain. I start looking and found Renu fall in love with the tub just looking at the web page. It doesn´t take much space can be inside or outdoors can keep your water cold and clean for 3 o 4 weeks, so I order it. need to be mention I live in Mexico so I order it to Laredo Tx and smuggle it to Mexico City. Got it about 3 weeks ago there haven,t been a day that I don´t use it. It activates your mind put your energy is different takes the stress out and you can achieve that with a 3-5 minutes plunge. I didn´t even thought to have the discipline to go in daily but is something that when you start you can´t stop.

Love my renu cold plunge . Built top notch and use it daily

We love our cold stoic. I'm ordering a 2nd one for our other home.

Fantastic product design & quality

I'm really happy with my Cold Stoic.

There are a few refinements I'd like to see, mainly being a digital control system that would enable the pump & chiller to run intermittently. I solved the problem with an $8 outlet timer, but having this integrated into the system would allow for more sophisticated control. I'm happy to provide ideas/suggestions to hone the feature.


The product and service provided to get set up, are outstanding.

100% percent! The very best!

I love my cold plunge. One of the best purchases ever for me! THANK YOU!🙏


I’ve had my Renu now for about 2 months. We use it 3-4 times a week and it’s been great for recovery and mental discipline. I also bought a sauna from Renu and the 2 together I couldn’t recommend enough. Also - the customer service and appreciation for you business is excellent!
