Frequently Asked Questions
What size water chiller do I need for a cold plunge?
For tubs between 90-150 gallons, a 1 HP cold plunge chiller is typically recommended for stable cooling and faster
recovery sessions.
Who this cold plunge chiller is for?
Perfect for:
Home gyms
Athletes
Biohackers
Recovery clinics
Wellness spas
Outdoor ice bath setups
What is a cold plunge chiller?
A cold plunge chiller is a refrigeration system designed to cool and maintain water temperature for ice baths and
recovery tubs. Unlike traditional ice baths, a dedicated chiller can keep water consistently between 36°F and 50°F
without the need for bags of ice.
A 1HP unit is considered the minimum recommended power for most residential plunge tubs between 100 and 150
gallons.
What temperature range can the cold plunge chiller reach?
Our 1HP cold plunge chiller can cool water down to 36°F. Lower than this risks freezing the water, which could damage the system. Even for experienced users, 36°F provides an intense and effective cold therapy experience, making it an
ideal minimum setting for safety and performance.
How fast does the cold plunge chiller cool the water?
The average cooling rate is 5°F per hour, depending on the ambient temperature, water volume, and insulation of your
tub. It's up to 3x faster than entry-level models.
Is the ice bath chiller for ice bath loud when operating?
The cold plunge chiller operates at a low to moderate noise level - comparable to a small air conditioner. It's quiet
enough for use in home gyms, garages, or backyards without causing a disturbance.
Is the cold plunge chiller easy to set up and use?
Yes! Setup is straightforward. Just connect the inlet and outlet hoses, plug the unit in, and set your target temperature.
The digital control panel makes operation simple, even for first-time users.
Does the ice bath chiller require a lot of maintenance?
Minimal maintenance is required. We recommend:
1. Change the filter cartridge regularly
2. Checking hose connections every few weeks
Is the cold plunge chiller compatible with any ice bathtub?
Yes - our water chiller for ice bath is compatible with most bath tubs.
It works with inflatable bathtubs like the one we offer, and for tubs without built-in ports, you can connect it using the
included submersible pump and hose setup.
What is the warranty coverage for the cold plunge chiller?
Two-year warranty. See the Warranty Policy for coverage and contact support for help.
Does the 1HP cold plunge chiller use a lot of electricity?
The 1HP chiller has a cooling capacity of 2600W. As an illustrative estimate, cooling water from 90°F to 39°F may use approximately 4.25 kWh, costing about $0.60 at $0.14/kWh. Actual electricity use and cost vary with water volume, starting and target temperatures, ambient conditions, tub insulation and your electricity tariff.
What are the clearance requirements for the 1HP Cold Plunge Chiller?
To ensure proper airflow and optimal cooling performance, we recommend leaving at least 10 inches of clearance around all sides of the chiller.
For even better ventilation and heat dissipation, especially in warmer environments or indoor installations a clearance of around 12 inches is ideal.
Proper spacing helps:
Improve cooling efficiency
Prevent overheating
Extend the lifespan of the chiller
Maintain stable water temperatures during extended use
We also recommend placing the unit in a well-ventilated area and avoiding enclosed spaces with restricted airflow.
What are the package dimensions and weight of the 1HP Cold Plunge Chiller?
The 1HP water chiller will be shipped from the nearest available warehouse based on inventory. Our warehouses are
located in New Jersey, California, and Georgia.

What Customers Are Saying About Ultra 1HP Chiller
Customer Reviews
Overall rating: 4.6 / 5 from 300 reviews.
Honestly a total game-changer for my recovery. This thing cools the water down crazy fast and holds temp without any issues. Big fan of the ozone and that external 20-micron filter—keeps the water super clean and it’s way easier to swap out than an internal one. The controls right on the unit are simple to use too. Definitely worth the money.
Great so far. Love the external filter for when I need to change it, and it runs pretty quiet while maintaining temperature very well. No complaints at all, it gets the job done.
I’ve got the chiller set up in my backyard next to the plunge tub. It’s been running daily with no issues. No cover, no special setup—just placed it on a flat spot and let it run. So far, very solid and low-maintenance.
I built my plunge around an existing tub and needed a chiller that could handle regular use. This was the missing piece that made the setup complete
I bought this for my husband but ended up using it after workouts too. It has become one of those purchases we both appreciate
I was upgrading from a smaller cooling solution and noticed the difference immediately. It made my setup feel much more complete
I spent weeks comparing different chillers before buying this one. What stood out about Plunge Chill was how helpful they were before I ordered. They answered my questions and made me feel confident about my choice
I upgraded from a smaller setup because I wanted something that could handle more frequent use. The difference is noticeable and I no longer have to plan around adding ice
This chiller completely upgraded my cold plunge setup. I no longer have to deal with ice and my recovery routine feels much easier to maintain
After years of using ice bags this feels like a completely different experience. Reliable cooling and very convenient for daily use
Man, this thing is a monster. I live where it gets super hot and my old setup could barely keep up, but this 1HP chiller handles it like it's nothing. It drops the temp fast and stays there all day. If you're serious about your plunges, just get this one and save yourself the headache of dealing with ice bags.
I use this almost every morning after training. The cold temperature helps me feel refreshed and ready for the day. I like that it’s always ready when I am.
The 1HP chiller has plenty of power for my plunge tub. It takes the water down to the temperature I like and maintains it well. The unit is a little noticeable when running, but the performance makes it worth it.
Very strong unit. Keeps temps stable and works well for daily use. Only reason I didn’t give 5 stars is because the unit is a bit heavy to move around once installed.
The cooling performance is excellent. Installation took a little longer than I expected, but once everything was connected, it worked great.
I started with just a basic tub and bags of ice, which worked, but it got old pretty quickly. After switching to a chiller setup, it honestly changed how often I use it. Now the water is already cold when I go outside, and I don’t have to think about prep. The tub itself holds up well when full, and I can sit in without it feeling unstable. It’s not something I look forward to every time, but I use it a lot more now.
I started using this after hearing about cold plunges on a podcast. Didn’t think I’d stick with it, but here I am, three months later, still plunging daily. The chiller keeps it perfectly cold and reliable. I feel calmer, sleep better, and it’s kind of addictive in a good way.
I run a small gym and this chiller handles multiple tubs effortlessly. Powerful and reliable for commercial use.
Fast, powerful, and easy to control. Makes daily cold plunges effortless. Love it!
The chiller is heavy but that’s expected with 1HP. The cooling performance is worth it—it keeps water icy cold consistently.
I’ve tried smaller chillers before, but 1HP is a whole different level. Water chills quickly and stays perfectly cold.
Perfect after hiking or cycling. Quick cooling, easy to maintain, and sturdy. Love it!
After long runs, this chiller is a game changer. Muscles recover faster, and the water is always perfectly cold. Totally worth it!
Exceeded my expectations. Keeps water at perfect plunge temps and is super easy to operate. Glad I bought it.
Paired it with my Plunge Chill tub and it works perfectly. Water gets down to freezing temps and stays cold even with multiple plunges.
This chiller has changed how I do recovery at home. It’s super easy to operate and keeps water icy cold without me having to babysit it. I love how I can set it and go about my day, knowing the water will be perfect when I’m ready to plunge. It’s a bit big but the wheels help a ton. Worth every cent.
I do a 3-minute cold plunge every night and this setup makes it effortless. No more hauling ice—just cold, clean, consistent water every time.
This chiller keeps the water cold exactly how I want it. The steady temperature control and build quality make it a great investment.
I’m in a small city apartment and space is limited, but this chiller fits in nicely with my plunge tub setup on the balcony. It’s quiet enough not to bother neighbors and strong enough to bring temps down even on warm afternoons. Great build and solid value.
Set this up near my backyard and it works like a charm. The water cools down fast and stays icy for hours. I love that I can just wheel it around when I want to store it away. It’s been a great addition to my recovery routine, especially after long hikes or runs. Really glad I invested in this.
I'm a cold plunge newbie and found this unit easy to use and pretty effective. It gets water down to the right temp quickly and holds it there. The noise is noticeable at startup but not too bad overall. I appreciate the portability with wheels since it’s heavy. Definitely made cold plunging a regular part of my routine.
I did a lot of research before buying because I didn’t want to mess around with poor build quality or bad service. This chiller checked every box—arrived fast, great instructions, tight construction, and it actually performs like advertised. Totally worth the price.
I do wish it were a little quieter, but it cools the water just the way I need. I've been using it for two weeks now, and I can definitely feel a difference in my post-workout recovery.
I run a small private gym and got this chiller for the recovery area. So far, it’s been solid with no problems. It cools the water pretty quickly and is simple to keep clean. Customer support was helpful and responded quickly when I had questions during setup.
I had no idea there was so much to learn about water care. Once I figured out the routine it became much easier
I replaced an older cooling solution that was inconsistent. The improvement in reliability was the main reason I am happy with this purchase
I built a larger plunge setup and needed something that could keep up with regular use. This has been a dependable part of my home recovery space
I am not an athlete or anything like that. I just wanted something that helped me feel better after long days sitting at a desk
I had an issue where the water was not circulating as expected. After checking the setup and cleaning the filter everything returned to normal
Good product overall. New users should learn the basics of water flow and maintenance before setting everything up
