Renu High-Flow Chiller

Our Renu 1/4 HP water chiller can be set to chill the water temperature down to as low as 36F (2.2C) & our magnetic drive water pump works with quiet, efficient, and reliable 24/7 performance. Featuring a magnet impeller assembly and an epoxy-encased power unit, our pump cycles an amazing 20 Gallons every minute and never gets contaminated with harmful oils or chemicals. Also, integrated into our system is a 2-stage filtration system with a removable large grate that catches larger debris and a flow-through, replaceable 50-micron water filter element for fine particles. Finally, our ultraviolet ozone generator discharges ozone into the water to help eliminate bacteria, viruses, and metals.

Intelligently Engineered, Designed, & Assembled in USA.

Our cold tanks are designed to last years. For example, our tanks feature a fully enclosed housing for the chiller system to ensure the longevity of all the electronics and pumps. Our tubs are Super Insulated for maximum efficiency and have a Leak Proof tank design. All of our products are constructed with the highest-quality components and have been extensively tested. Performance and reliability were considered in every step of our design process. Finally, we proudly design and assemble all of our cold tanks in Southern California.

Beautifully Designed for Indoors or Out.

Customize your tank for your gym, garage, or outdoors space. Our designs are minimalist, modern, and can match any environment. We believe quality design deserves the best materials. We use beautiful Natural Woods like Cedar and Redwood, which are treated with all natural oils and no chemicals. Every unique unit has its own artful characteristics.

Quiet and Energy Efficient

Our fully sealed design combined with our custom high-flow chiller allows your cold tank to operate at a whisper.  You’ll barely notice it’s there! Our thermally insulated tub keeps water colder and separated from the elements.  This allows the chiller to work more efficiently and saves 30% more energy compared to other cold tanks.  Our tanks are so well insulated, that in our tests, water stays below 60 degrees F even 24 hours after we've fully unplugged our unit.

Renu Cold Stoiic 2.0 is a Homerun!

Love our Renu Cold Plunge! It’s so easy to maintain, so easy to use and looks very stylish! I think this is the best cold plunge on the market hands down!

Jeffrey Tanski (Loganville, US)
Renu your Thrill!

We absolutely love it. My wife and I are currently plunging 2 to 3 times a day. The customer service has been fantastic with answering calls and emails. Get the chiller to cool down the water to 32°F and you have your competition beat.

michael citrone (Los Angeles, US)
Finally got the Renu after years of ice and water!

Keeps the water fresh and extremely cold.
I think they provide more detailed instructions.
Would be awesome if you could control temperature through a phone app. Perhaps later on down the road.

You get what you pay for!

Everything about this cold plunge is as it’s advertised! The unit looks great and holds the temperature even outside in the heat. It’s spacious, comfortable, durable, and easy to use and set up. Just make sure to buy plenty of extra filters. Great product!!! Couldn’t be happier with it.

My Renu and Stoic 2.0 Experience

I ordered the Stoic 2.0 back on May 16th when the lead time was 3-6 weeks. The unit got delivered on July 20th, a tick north of 9 weeks later. If I could make one recommendation to Renu it would be to promise small and deliver big on delivery dates. None the less...they did take care of me on this and it was much appreciated. When the unit arrived, it looked fantastic. Upon inspection with the delivery driver, there appeared to be no damage from delivery, so we sent him on his way. Upon a little closer inspection once we had the unit to ourselves, there was a tiny little chip in the breath decks finish, to which Renu has since sent me a kit to try and repair that. Shortly after that, the chiller developed some kind of ticking sound that would be present when the unit was chilling. Renu again took care of that and sent out a replacement chiller. I also had an issue where when trying to take a look at the chiller and I shut off the ball valves for the in and out lines going to the tank, the check valve on the ozone unit did not function properly and had a feedback of water coming through the ozone machine. Renu followed that up as well and sent me a new check valve to replace the faulty one.

Renu has been extremely responsive to every email and more than helpful in every situation I've encountered in the short couple of weeks I've had it. Both Chanel and Paige have been great and a ton of help. The only thing I would recommend to Renu is that if a unit is going to take 3-6 weeks or 4-8 weeks or what I believe is now 6-10 weeks......just say 10 weeks. If you deliver it in 6......well, then you have a very happy customer. My experience with the unit has been great. I'm in it every day at 5am and it's been a great addition to my daily health routine. The chiller has been holding the set temp within a degree or two every day. The unit is worth the wait and you'll be happy you made the purchase.


Thank you so much for the thorough review, and I truly apologize for all the issues you experienced. I'm glad we got you all sorted out and headed in the right direction. In regards to the lead times, we do try to do exactly what you suggested, but we got slammed with orders in May and I was a little late in bumping up the lead times. It was my personal mistake so I personally apologize.

Thanks for your business as well as your patience and understanding. Sorry your experience wasn't perfectly smooth. Please reach out if you need anything else at all.

Fits Tall Users, Well Built! Wish it would cool below 40F

First off, I am 6’4” and 230lbs. I was skeptical when I saw the claim that the Cold Stoic 2.0 would comfortably fit someone several inches taller than me. I could not find any reviews or examples of someone my height getting inside. After several plunges, I am happy to report that I fit just fine.

The build quality of the unit is superb and well worth the additional cost in my opinion. The body of the unit appears like it will last a lifetime and the electronics will be easy to service/replace down the road as needed.

Ergonomically, I like the fact I don’t feel like I’m lying down in a bath tub while using it. The section above the mechanical housing which Renu refers to as the “breath deck” makes getting in and out easy, despite the taller height of the tank.

Because no review is complete without mentioning the drawbacks, I noticed with the unit inside I can smell the ozone when in the same room. Not a big deal but I haven’t seen it mentioned elsewhere. Also, there were some small scuffs on the exterior of the unit upon delivery (see image). I emailed support and they settled the issue to my satisfaction the next day. Part of the reason I chose Renu is their customer service reports, and I’m glad I did!

The reason I gave 4 stars instead of 5 is because they advertise the chiller can be set down to 36 degrees. However, the water temperature will not go below 40 degrees. This has been my experience with the unit indoors and out of the sunlight (50% humidity and around 75F room temp).

JON M (McKinney, US)

The only thing better than buying a Cold Stoic 2.0 was starting cold plunging to begin with. Cold plunging has changed my health and my life. It has been probably the most effective treatment for mood and anxiety. I have never felt this good.

The Cold Stoic is everything I could have wanted and worth the investment as I plunge daily. It is high quality and easy to maintain. I am using it in North Texas area and it is in an outdoor building with no AC and it keeps the water perfectly at 47 degrees all day even when the heat index reaches 114.

I had questions before buying the unit and I called multiple companies. Renu was the only company that was able to answer my questions and took the time to get in touch with me. The other companies weren't interested in providing answers. Renu is responsive and care about their customers.

The only warning I'll give people is that the unit is extremely heavy even without water and with four grown men we still had to use floor dollies to move it off the pallet and to it's final location so get a team ready when it's time to move it.

My Daily Reset

Love my tub. It’s an integral part of my morning practice. I highly recommend RENU, and the Cold Stoic 2.0 if you intend to make cold plunge part of your commitment to your body.

Charles G (Weston, US)
Really Amazing

This is my first cold plunge machine after doing other cold plunges. Very high quality. Great aesthetics and hold temps very consistently. I live in South Florida and currently in July it is over 93° outside. We have our unit placed in our back patio area so it’s not in direct sunlight but it is hot outside. This unit has held its temperature within 1 to 2° consistently 24 hours a day. What I like most about this unit is the fact that it has a great build quality and it does not look like a porcelain bathtub with an external unit. Everything is housed within the entire system, and looks very clean and put together. Most other companies probably build similar quality units but look Cheap with plywood exteriors or with the chiller units outside connected by hoses. They mostly look like bathtubs, not that they work any different, but I don’t want to see a bathtub in my backyard. So far so good hopefully this will be in service for many more years to come. I purchased the extra five year warranty just to be certain.

Audrey (Phoenix, US)
Game changer

I live in Arizona, and on hot days (which is every day) my cold plunge is making it possible for me to energize and stay cool. I love it!
