Immersing yourself in temperatures ranging from 40°F (4°C) to 60°F (15°C) can bring a host of impressive advantages, such as decreased inflammation and muscle soreness relief.

Regular use of a DIY cold plunge tub may result in increased focus and even mood improvement for those affected by depression. And don’t forget the bonus reward – enhanced immunity when you take advantage of cold plunging routinely.

Physical Improvements

Research has found that submerging oneself in ice-cold water can help reduce inflammation by decreasing blood flow and numbing nerve endings, while also aiding injury recovery. Cold exposure – such as adding some cubes of ice to the tub – could even be effective for chronic autoimmune issues involving high levels of swelling.

Regularly engaging with an icy dip once or twice weekly may maximize these physical benefits from plunging into frigid waters!

Mental Health Benefits

Cold water immersion activates the body’s response to cold temperatures, which boosts concentration and alertness while releasing hormones like endorphins that uplift moods and amplify cognitive performance.

Several studies provide promising evidence for its potential in treating chronic autoimmune inflammation, anxiety, or depression issues. Although more research is necessary here too, it clearly showcases how advantageous a regular practice with these cool waters can be on our psychological wellbeing.

Immune System Boost

The advantages of engaging in cold plunge therapy are quite remarkable. Regular cold water therapy helps strengthen your immune system by increasing the production of defense cells, and there is also evidence that this type of activity helps reduce chronic autoimmune inflammation and improve insulin sensitivity as well.

Reports from individuals who regularly partake in swimming or other activities involving submerging their bodies into cold water suggest various benefits such as increased energy levels and mental clarity, decreased rates of catching a common cold, and improved overall health.

A DIY Cold Plunge Tub at home offers an efficient way to benefit from exposure to colder temperatures through its powerful effects on improving one’s immune system function while reducing inflammation simultaneously.

DIY Cold Plunge Options

Repurposed freezers, oak barrel conversions, stock tank transformations, or even an inflatable tub set up – there are plenty of ways for you to get started on crafting that perfect experience. Whatever you choose, ensure that the container is large enough to submerge your body (and vagus nerve in the neck) comfortably. Additionally, it should be made of a durable material that can withstand temperature extremes.

Let’s delve deeper into these choices so we can make sure they meet all your needs before trying them out yourself. Freezer chests provide excellent insulation against the chill as well as offer ample storage space. Meanwhile, barrels filled with icy water can be easily adapted for use, though keep in mind it won’t maintain temperature like chest coolers do. Stock tanks offer more features such as steps or jets too, but remember to buy one big enough! Inflatable tubs present portability advantages over other alternatives while still giving off much-needed frigid temperatures when needed.

Nowadays getting access to a customized version of cold plunge therapy has become easier than ever thanks to these ingenious DIY ideas. This is your opportunity to create your own cold plunge! Let us know what works best for providing optimum relief.

Repurposed Freezer Chest

Cost

Free – $300

Pros

  • Well insulated

Cons

  • Heavy

A repurposed freezer chest is a popular solution for a DIY cold plunge.

It can offer complete temperature controller and using silicone sealant with caulking guns ensures watertight seals so you can submerge safely. As an added bonus, frozen water bottles help to keep your desired level of chill in the water.

For just around $200 on average, these chests provide all the health benefits without breaking your bank account.

Remember – Anything that combines a tub of water and electricity, you have to be super careful. Or just use ice as a chiller and your risk of electrocution goes way down.

Oak Barrel Conversion

Cost

Free – $180

Pros

  • Inexpensive
  • Looks nice

Cons

  • Wood degrades
  • Cramped space
  • No insulation
  • If used, odors may still exist
  • You’ll need a ladder or other device to enter/exit the barrel

An oak barrel conversion is budget budget-friendly and easy-to-build DIY cold plunge option. This usually consists of a 55-gallon barrel (I prefer closer to 75-gallon if available) or an oak barrel, making it a rustic yet cost-effective alternative for chilly plunging therapy.

Oak barrel transformations provide not only inexpensive alternatives when compared to more sophisticated setups but are also easily assembled without too much fuss involved during assembly or post-maintenance upkeep thereafter.

You will need to install a spigot for draining and cleaning purposes. To do this simply drill through the container’s walls with an appropriately sized hole before sealing off the tap securely in place. Caulk around the spigot to ensure a watertight seal.

With a few simple preparation steps, transforming your humble old barrel into an exhilarating therapeutic bath can be completed quickly.

Tip: Some wineries sell their old barrels. Call them up to see if this is an option.

Stock Tank / Horse Trough

Cost

$120 – $200

Pros

  • Solid
  • Some come with a spigot installed

Cons

  • Heavy
  • No insulation
  • Lids are typically extra

These durable containers, usually used to store water for livestock, are spacious enough for multiple people or friends so that they may benefit from the therapeutic benefits of this type of therapy together.

We like the Rubbermaid 100 gallon stock tank or the Agrimaster 103 Gallon Galvanized Stock Tank. Both are well made and should last a very long time. The Rubbermaid has a spigot already installed so modifications will be minimal when you get it home.

To ensure an ideal temperature in these large stock tank tubs, additional insulation might be required as well as climate control systems.

A DIY cold plunge with a stock tank allows you to enjoy all the advantages that come along with it, including increased size and robustness, enhancing your overall immersion into its icy waters!

Trash Can Conversion

96 gallon trash can be used as a DIY cold plunge

Cost

$100

Pros

  • Solid

Cons

  • Feet area is cramped
  • No insulation
  • You’ll need a ladder or other device to enter/exit the barrel

A large, 96-gallon trash can will already be watertight, and typically comes with a lid that will keep out leaves and other debris.

While they don’t have any insulation, you could wrap them in a DrumQuilt or similar solution to keep the water colder when not in use.

Due to the large wheels that come on trash cans this big, the “foot area” is smaller. It’s not a big inconvenience but people with larger feet may be crouching in a “toe down” position.

Also, I have seen some outside edges near the opening that are very sharp. Be aware of this and sand them down in order to avoid any cuts.

Inflatable Tub Setup

Cost

$100 – $1,000

Pros

  • Portable
  • Space saving
  • Inexpensive
  • Lightweight

Cons

  • May not last as long as other materials

For a DIY cold plunge, an inflatable tub provides the perfect solution for those with limited space or mobility. These are easy to set up and store away when not in use and are convenient options if you don’t want to do a lot of customization. With an inflatable tub, adding ice baths to your wellness routine is both simple and practical.

To begin, inflate the tub to the desired pressure (typically around 10 PSI which takes about 5 minutes) and make sure that it is placed on level ground.

Fill the tub using a garden hose then cool the water along with any desired additional temperature adjustments using ice or ice packs.

With so many benefits available through this form of therapy such as improving circulation, pain relief, immune system boost, etc., investing in an inflatable tub makes good sense, easily creating a unique cold plunging experience at home.

Creating Your DIY Cold Plunge

Step 1: Choose the Right Location

Ideally, you want a spot that is level and offers privacy, as the cold plunge is often a deeply personal experience. It should also be easily accessible, ensuring you can seamlessly transition from the cold plunge to a warm shower or cozy robe. If you have a spacious backyard or patio, that could be an excellent location.

You’ll want to make sure you can add or drain water easily.

Once your tub is full of water, it will be too heavy to move (It can weigh up to 1000 pounds). Make sure the location is structurally sound to hold this much weight.

Step 2: add a Spigot

You need to drain the water from time to time for hygienic purposes. The easiest way to do that is by a spigot.

The EarthMinded “Add a Spigot Kit” works in most situations and will provide a professional look and feel to your own cold plunge tub. It is inexpensive and comes with the drill bit that will be needed during installation.

Step 3: Waterproof and Sanitize the Container

Your container is the heart of your DIY cold plunge. It has to be watertight and clean when you use it.

Waterproofing

Before filling your container, make sure it’s completely watertight. Seal any potential leaks or gaps using a waterproof sealant (aka caulk). This will not only prevent water from escaping but will also ensure that your cold plunge maintains its desired temperature more efficiently.

You may not know what areas will leak initially, so be ready to fill the tub and look for problem areas to fix. You’ll need to drain the tub in order to seal it. Waterproof caulk is what we use and it’s important for you to seal from the inside of the tub, not from the outside.

Sanitization

Clean the container thoroughly before the initial use and establish a routine for periodic cleaning. A mixture of mild soap and water can work wonders in eliminating any bacteria or impurities that may accumulate over time.

You’ll want to invest in pool-safe cleaning agents and chlorine tablets to maintain water quality without harming the integrity of your container.

Step 4: Consider Insulation

To maintain the cold temperature of your plunge, consider insulating the container. This is especially crucial if you plan to use your cold plunge throughout the year, including colder seasons.

Without insulation, you will get wild temperature swings that will cost you time and money from purchasing and transporting ice all the time.

Insulation can be achieved using foam boards or insulation blankets, creating a more energy-efficient setup. DrumQuilt makes insulated sheeting that can be used to wrap your tub whe
