The Primal Plunge has completely changed how I start my mornings. The guided sessions keep me consistent and motivated, and the scenery on the screen makes it feel like I’m plunging in a mountain lake. It’s become a ritual I actually look forward to.
Jason Miller
I’ve tried other plunges, but the build quality on this one is much better. The water stays crystal clear, the pump is very quiet, and swapping filters is insanely easy. You can tell they thought about every detail.
Davey Fisher
I'd done a few cold plunges before and I decided to bite the bullet and buy a good one. Within a few weeks, I got used the cold water and it definitely helped my energy levels and mood. The plunge cools down fast and holds temp even in our hot garage. I'm actually addicted now and it's been a great investment.
David Chen
The touchscreen and app are pretty cool. I wasn't sure I really needed it but it definitely adds to the experience. It distracts you from focusing on the clock and the coaches have pretty good motivation topics in each video. Plus it sends you push notifications that keep me accountable.

Common Questions

What makes your chiller different?

There are good chillers on the market and garbage chillers. It's hard to tell as a consumer what is what. So, we bought several of the chillers on the market, took them apart, and compared them to our chiller, side by side. Watch this video to see how our chiller stacks up.


Chiller Comparison Video

How cold does it get?

Both our chillers can cool to 34º and heat to 104º. Most users will find benefits with water kept at 45º-55º.

How long is setup?

Most users will be able to unpack, connect, and setup our cold plunges within 15-30 minutes. Our app guides you through the setup process using a walkthrough video specific to your model.

Is it noisy?

When cooling, the chiller runs at 55db. When only the pump is circulating water, the noise level falls to 44db which is equivalent to a library or quiet dishwasher/fridge.

Can I use it outdoors?

All of our chillers and tubs are engineered for the outdoors. We offer two touchscreens. One rated for indoors and one rated for outdoors. Ensure to select the outdoor touchscreen if you plan on locating it outdoors.

Is there a monthly subscription?

For customers who purchase a Primal Plunge in 2025, they will receive a lifetime free subscription to PrimalOS and never pay a subscription fee.
