Cold & Clean
Our Renu 1/4 HP water chiller can be set to chill the water temperature down to as low as 36F (2.2C). Our 50-watt magnetic drive water pump works with quiet, efficient 24/7 performance. Also, integrated into our system is a 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.

I’ve been using the Cold Stoic 2.0 for a while now and it's a game changer. Self-contained, no need to haul/buy ice, and easy to care for. Looks great beside my sauna, too!
One thing that really improves convenience is having it plugged into a WEMO switch, so I can control it from my phone, making turning it on or off a lot easier, especially when I want to keep things quiet during a gathering.
Speaking of that, there are a couple of minor downsides. The filter is a little awkward to place, and, as mentioned above, the unit runs at around 55 dB — like a dishwasher. Just annoying enough that I will turn it off if we’re hanging out nearby. Those are nitpicks, and in no way worthy of downgrading.
It’s been a solid purchase and easily deserves 5 stars.
If I could give 10 stars for customer service, I'd do it.
- CRChuck R.Verified BuyerReviewingThe Cold Stoic 3.0I recommend this productRated 5 out of 5 stars2 months agoLife Changing
The Cold Stoic 3.0 isn’t just a cold plunge — it’s a life upgrade. This thing has become my daily ritual, my reset button, and my secret weapon for mental clarity, stress resilience, and physical recovery.
Form meets function in all the right ways. The design is sleek and solid — no cheap plastics or gimmicks. It looks sharp enough to show off and performs like a workhorse. Clean lines, easy to drain and maintain, and stays cold consistently. Like, ice-in-your-veins cold.
What really makes it a game-changer though is how it fits seamlessly into my routine. Whether I’m doing Wim Hof breathing beforehand or just jumping in after a grind of a workday, the 3.0 delivers — every time. The cold hits, the mind clears, and the body snaps into gear. It’s better than coffee, therapy, and meditation rolled into one.
I’ve been using it daily and honestly, it’s non-negotiable now. Traveling? I miss it. That’s how you know it’s more than a product — it’s a lifestyle enhancer.
If you’re looking to level up physically, mentally, or just reclaim your edge — stop looking. Cold Stoic 3.0 is the real deal.

Best way to stress-test your day!
There couldn’t be a better system out there. The app allows you to check, change settings, flip on your light, schedule, etc. On a cold winter day I took the 3.0 a complete lap around the track in under 36 hours. From below 40 to 104, and back to below 40 again, amazing!
