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.

Customer Reviews

Overall rating: 4.6 / 5 from 300 reviews.

Customer photo review of 1HP COLD PLUNGE CHILLER

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.

Customer photo review of 1HP COLD PLUNGE CHILLER

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.

1HP COLD PLUNGE CHILLER

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.

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.

Customer photo review of 1HP COLD PLUNGE CHILLER

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.

Customer photo review of 1HP COLD PLUNGE CHILLER

The cooling performance is excellent. Installation took a little longer than I expected, but once everything was connected, it worked great.

1HP COLD PLUNGE CHILLER

Customer photo review of 1HP COLD PLUNGE CHILLER

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.

1HP COLD PLUNGE CHILLER

Customer photo review of 1HP COLD PLUNGE CHILLER

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'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.
