Filling Your Tub for a Cold Plunge

Imagine the invigorating chill of immersing yourself in your own home cryotherapy bath. Yes – turning your bathtub into a cold plunge tub is not only possible but also quite feasible. So, how do you begin? It all starts with filling your tub up with cold water.

In any case,

All you need is to turn on your tap and let it fill. If the tap water doesn’t feel sufficiently chilled, not to worry. There’s a workaround for that – ice! By adding this element, you’ll start to transform your tub into an ice bath.

Adding Ice to Achieve the Ideal Cold Plunge Temperature

You see,

The secret behind an ideal homemade cold plunge experience lies in achieving the perfect temperature. Now that I think about it, isn’t it fascinating how something as common as ice can provide therapeutic benefits?

Add ice gradually until you reach somewhere around 39°F-59°F range; often considered as an ideal temperature for a cold plunge or an ice bath. It might be useful to have a thermometer handy for this purpose. This way, you are creating what I like to call a DIY cold plunge setup right within the comfort of your home.

Maintaining Water Quality for Repeated Use

If like me, there’s no way you’re going drain this therapeutic pool after just one use, then maintaining water quality should be high on your priority list.
You’re probably wondering: How could I maintain my so-called “chilled soaking tub” for longer use?

All things considered,

You could add a little bit of hydrogen peroxide or chlorine to the water. However, never mix these chemicals together since they react with each other. Maintaining clean water is not just cost-effective but essential for a healthful cold therapy bathtub experience.

Insulating Your Tub for Efficient Cold Temperature Retention

Insulation is key to maintaining the cold temperature of your ice soaking tub. You see, without proper insulation, your “DIY cold plunge” might feel like an ordinary lukewarm bath.

In any case,

To make it more efficient, consider insulating your tub if possible. Remember that the insulation goes around the exterior of the tub and not inside where water goes.

Conversion Options: Turning a Hot Tub into a Cold Plunge Pool

If you happen to have an unused hot tub or spa lying around, why not convert that into a cold plunge pool?

Now that I think about it,

You can plumb chilled water supply and return lines from a chiller into your spa system. Just like that, you’ve transformed your old hot tub into an at-home ice bath conversion!

Commercial Solutions for Creating an At-Home Cold Plunge

Sometimes DIY solutions might seem too daunting or time-consuming.

In any case,

Fear not! There are commercial solutions such as CryoHome Ice Bath devices available in the market that make this process easier and faster by chilling bathwater without you having to add ice manually.

Duration and Adjustment: Getting Used to the Cold Plunge Experience

Just like any new experience, one needs time to get used to cold plunges. It’s recommended for beginners to start with short durations such as 15-30 seconds and gradually work up towards longer immersions.

Safety Precautions When Taking a Cold Plunge in Your Bathtub

All things considered,

Always be mindful of safety when taking an ice bath or doing any form of intense hydrotherapy. Listen to your body’s signals and exit the bath if you feel too uncomfortable or begin showing signs of hypothermia like uncontrollable shivering, numbness, or disorientation.

In conclusion,

Transforming your bathtub into a cold plunge tub isn’t as difficult as it may seem. Whether for therapeutic purposes or simply an invigorating refreshment, a DIY cold plunge could be just what you need.
