Ice baths or cold plunges are amazing ways to refresh and recover after a hard workout or a long day. But to fully enjoy the benefits, it’s important to know how to keep ice bath water clean.

A clean ice bath ensures you’re not sitting in a pool of germs and keeps the experience enjoyable. Let’s explore some essential tips for maintaining crystal-clear water in your cold plunge.

1. Rinse Off Before Getting In

Before you hop in, use a water hose to spray off any sweat, dirt, or hair from your body. This simple step prevents grime from ending up in your ice bath.

Plus, if you’ve got hair products or deodorant on, rinsing will help keep the water balanced and improve the lifespan of your filters and pumps.

2. Keep Your Tub Covered When Not in Use

When you’re not using it, make sure to keep it covered. This simple step helps remove unwanted debris like leaves, dirt, and bugs from your water.

Most cold plunges come with covers, but if yours doesn’t, make sure to find one that seals tightly. It’s a quick and easy habit that will save you a lot of cleaning work later.

3. Remove Visible Debris Using a Skimming Net

Sometimes, even when you’re careful, debris like grass, dirt, or small leaves can end up in your ice bath. It might seem like a tiny problem, but those little pieces can make your water look dirty and cause bacteria to grow.

That’s where a skimming net comes in handy. Just run it over the surface of the water to scoop up any floating debris before it has a chance to sink to the bottom. It’s a quick and easy task that doesn’t take much time.

Plus, it’s satisfying to see all that junk disappear. You don’t need to do this daily, but checking for debris regularly can make a big difference in how fresh your ice bath feels.

4. Use Food Grade Hydrogen Peroxide for Sterilization

Adding a small amount of food-grade hydrogen peroxide to your water can work wonders. This safe and effective solution helps kill harmful bacteria and even helps your water chiller and pump.

Add about 1/2 cup every 1-2 weeks and about one cap full weekly!

5. Use an Ozone Water Filtration System

For the cleanest possible water, I recommend an ozone water filtration system. Ozone, a natural molecule, purifies your water by breaking down and removing contaminants.

Having an ozone system in place means you don’t have to add a bunch of chemicals, other than food-grade hydrogen peroxide and stabilizer, to your cold plunge or ice bath.

As a safety precaution, keep it turned off while you plunge, and make sure to wait at least 30 minutes after it has been turned off before getting in the tub.

6. Use Water Stabilizer

Have you ever wondered how to keep your ice bath water from turning green or feeling harsh? Water stabilizers are your answer! With only a FEW DROPS every month, you balance the water’s chemistry, making sure it’s neither too acidic nor too alkaline.

Think of it like adding a pinch of salt to your food—it makes everything right without much effort. So, next time you’re prepping your cold plunge, don’t forget this small but powerful step. Your skin and senses will thank you!

7. Clean Your Strainer Every 2-4 Weeks

Your strainer is like the gatekeeper of your ice bath. It catches all those tiny bits of dirt and debris before they can mess up your water. But it needs a little care to keep doing its job well.

Every 2-4 weeks, take some time to clean it thoroughly. Use a toothbrush or a scrubber to get into all the little nooks and crannies. It might seem insignificant, but it makes a big difference.

Additionally, it helps your entire system work more efficiently.

8. Use a Hose Filter

Using a hose filter adds an extra layer of protection for your ice bath. When you fill-up your tub, water from the hose can carry tiny impurities that you might not see but can still affect the cleanliness of your bath. A hose filter helps catch these impurities before they enter your tub.

If you’re already taking all the other steps to keep your ice bath clean, using a hose filter just extends the life of your other components. Trust me, this will save you hundreds and make the plunging experience so much better!

9. Change Your Pump Filter Every 2-3 Weeks

Changing or cleaning your pump filter every 2-3 weeks is essential. Over time, debris and grime build up in the filter, and if left unchecked, it can start to smell bad and even clog up the system.

This makes your water dirty and affects how well the water circulates, so make sure to do this step.

10. Circulate Your Water

When water stays still, it becomes dirty and eventually starts to stink. But with constant circulation, your water has a better chance of staying fresh for longer.

Circulating the water also helps spread the hydrogen peroxide and stabilizing agents evenly, which prevents any buildup of grime.

I use a small submersible pump, which does the job well, but you could also use a circulation jet. Both are available on Amazon for under $100.

11. Empty and Wash Your Tub Every 3-6 Months

Every 3-6 months, empty all the water from your tub and scrub the heck out of it (using a rubber brush only). Use this cleaning soap and rubber brush to get into all the corners and crevices. This helps remove any built-up grime or residue that could affect the quality of your next plunge.

When scrubbing, pay attention to areas that might not be visible at first glance. Those hidden spots can harbor bacteria and grime. Once you’re done cleaning, rinse the tub thoroughly to make sure no soap residue is left behind. Then, let it dry completely before refilling it with fresh, clean water.

A clean tub not only looks better but also works better. It ensures that your water stays clean longer and the entire system runs smoothly. Plus, it just feels good to know your cold plunge is spotless.

*Note: Unplug any water chillers or pumps before you start scrubbing your plunge tub so you don’t accidentally damage anything.

12. Completely Change Your Water Every 3-6 Months (even if you don’t wash the tub itself)

If you’re only going to do one of these 12 tips, make it this: drain your ice bath every 3-6 months and refill it with fresh, clean water.

Think of it like a factory reset. The old water collects chemicals, bacteria, and other impurities you can’t always see, but trust me—they’re there. Dump that junk water and start fresh!
