How to Set Up Filtration, Ozone & Temperature Control for Your DIY Chest Freezer Ice Bath

WATCH ON YOUTUBE

Welcome to Grounded Ginger HQ — in this guide, I’m showing you exactly how to set up your DIY chest freezer ice bath using my Filtration, Ozone, and Temperature Control Kit.

This setup will help you maintain clean, safe, and stable water temperatures all year round. Whether you're new to cold exposure or upgrading your plunge, this guide will show you how to wire and place every component the right way.


Safety First

Although I’m fully insured, certified, and accredited in my field, your safety is your responsibility.

The Power Setup: What Plugs Into What?

At the heart of this entire setup is your surge-protected power board with at least three available sockets. This is where everything connects.

Here’s what you’ll be plugging in:

  1. Fully Submersible Water Pump

    • This circulates the water and keeps it moving — essential for both filtration and ozone sanitation.

  2. Ozone Generator

    • Plugs into the board and helps sanitize your water, keeping it fresher for longer.

  3. Thermostat Controller (Inkbird or similar)

    • Also plugs into the board. This controls your chest freezer’s temperature.


How the Thermostat Works

Your chest freezer plugs into the cooling socket of the thermostat unit.
The thermostat probe is placed inside the chest freezer, dangling in the water. It reads the temperature and switches your freezer on and off automatically, helping you maintain a consistent plunge temp while saving power.


Ozone Connection Options

There are two ways to run your ozone tube:

  1. Through the Pump:

    • Connect the ozone line to your pump. When ozone is turned on, the pump will help circulate the ozone through the water.

  2. Using the Diffuser Stone:

    • Simply plug the diffuser stone onto the end of the ozone tube, place it in the water, and let it run.

Both work — just depends on how you want to integrate it.


Safety Switch (RCD or GFCI)

You’ll want to plug your power board into a residual current device (RCD) or GFCI — available from your local electrical or hardware store. This adds another layer of protection by cutting off power in the event of a fault.

Your RCD/GFCI plugs into your main power outlet, and then your power board plugs into that.


Mounting Your Gear

Here’s how to mount each component safely:

  • Pump: Fully submerged in the water

  • Ozone generator: Mounted outside the freezer

  • Thermostat controller & power board: Mounted outside too

You can use a weatherproof box or build a simple housing unit around your chest freezer. Even a set of drawers can work — just ensure everything is safe from water, weather, and spillage.


Final Wiring Tips

You’ll end up with:

  • Two wires and one tube running into the freezer

  • Keep these close to the lid hinge to prevent kinking

Final Thoughts

With just a few core components — a submersible pump, ozone generator, and thermostat controller — you can build a powerful at-home ice bath that’s safe, low-maintenance, and efficient.

My goal is to make cold exposure safe, affordable, and easy to do at home — and this setup is proof of that.
