What is an Ice Tub?

An ice tub is a container filled with cold water and ice used for cold water immersion therapy. It's also known as a cold plunge or ice bath. You can purchase purpose-built ice tubs or build your own, which we’ll teach you today. However, before we do that, let’s cover the main benefits of having your own ice tub. 

The Benefits of an Ice Tub

Immersing yourself in an ice tub can provide several potential health benefits, including reduced inflammation, improved circulation, and aiding muscle recovery.

Here’s why you should consider making your own ice tub at home:

Reduces Inflammation

Cold water constricts blood vessels, reducing inflammation and swelling in the body. This can be particularly beneficial for athletes who engage in intense physical activities that may lead to inflammation and for those who suffer from inflammatory health conditions. 

Improves Circulation and Aids in Muscle Recovery

When you exit the ice tub, your body experiences vasodilation or the expansion of your blood vessels, which increases blood flow and oxygen delivery to your muscles and surrounding tissues. This improved circulation aids in recovery after intense exercise and promotes overall well-being.

Cold water immersion can help alleviate muscle soreness and stiffness by reducing muscle damage and promoting faster recovery, as indicated by this study. This allows you to get back to your training or daily activities more quickly. 

An Immunity Booster

Regular cold water immersion can boost your immune system, increase your tolerance to cold temperatures, and enhance your overall resilience. Indeed, studies confirm that regular exposure to cold water increases immunity and stress response, as illustrated by this study on cold-exposed and cold-adapted humans. 

Mental Health Benefits

Ice tubs can also provide mental health benefits, such as reducing stress and improving mood. 

Studies show that cold water exposure leads to a sudden release of dopamine and serotonin, which are both natural feel-good chemicals. These chemicals can lead to a sense of well-being, relaxation, and potential reduction in stress.

If you’d like to reap the benefits of cold plunging but would rather not have to make your own ice bathtub, visit Icetubs for state-of-the-art dedicated ice baths.

Now that we know the benefits of ice bathing, let’s discuss the benefits of making your own ice tube at home. 

Why Make Your Own Ice Tub?

Making your own ice tub offers several advantages over purchasing a commercial one, including saving money and creating a tub that perfectly suits your needs.

Here’s why you might want to create your own ice tub instead of buying one:

Cost Savings

Building your own ice tub is significantly cheaper than buying a pre-made one. You can save hundreds or even thousands of dollars by using readily available materials and tools, especially if you recycle or reuse existing materials that you may already have.

Customizable Size and Design

When you make your own ice tub, you can choose the size and design that best fits your space and preferences. Whether you have a small apartment or a spacious backyard, you can create an ice tub that fits the intended area and yourself.

Convenience

Having an ice tub readily available at home means you can enjoy the benefits of cold water immersion therapy whenever you want, without the need to travel to a gym or spa. This convenience makes incorporating cold therapy into your regular self-care routine easier.

Now that you’ve decided to build your own ice bath, let’s move on and discuss the materials and steps required to make it all come together. Although, if you’d rather avoid this process altogether, the IceBarrel XL is a ready-to-go ice bath with advanced convenience and comfort features. 

How to Make Your Own Ice Bath Tub

With the informational aspects of cold plunging and building your own ice bath covered, let’s move on to our main purpose: building an ice bath at home. Let’s start by discussing what materials you’ll need for the job.

Before you can start building your own ice tub, you’ll need to gather some essentials, the main component of which is a large container or tub. 

To build your own ice tub, you'll need the following materials:

• A large tub or container (at least 300 liter for full immersion)
• Insulation materials (foam boards or spray foam)
• Waterproof sealant
• A drill (for drainage holes)
• A plug or stopper (for the drainage hole)
• Ice (depending on the size of your tub, you might need a significant amount)

Now that you’ve gathered your materials, let’s go through a step-by-step process on how to make your own ice bath, starting with choosing a container. 

Step 1: Choose a Suitable Container

The first step in the process is selecting the right container for your ice tub. Make sure that the container is durable and able to withstand the weight of the water and ice. You’ll also want to look for a container that is watertight and large enough to suit your needs.

Several tub or container options are available, such as stock tanks, plastic drums, and chest freezers. 

Let’s take a quick look at each. 

Stock Tank

Stock tanks, commonly used for livestock, are a great choice for an ice tub. They are durable, watertight, and come in various sizes. Look for a tank made of high-density polyethylene (HDPE) or galvanized steel for long-lasting performance.

Plastic Drum

Large plastic drums, such as those used for food storage or industrial purposes, can be repurposed into an ice tub. Ensure the drum is clean and has not been used to store toxic substances. A 55-gallon drum is a common size that works well for most people. However, a modified chest freezer is best for the most comprehensive ice bath. 

Modified Chest Freezer

For a more advanced setup, you can convert a chest freezer into an ice tub. This option requires more work but allows you to control the water temperature more easily. 

You'll need to remove the compressor and cooling elements, seal any holes, and install a drainage system, although this version offers the greatest versatility for DIY ice baths. Whatever you choose, you’ll need to adjust the container, so let’s move on and do just that. 

Step 2: Prepare the Container

Once you've chosen a suitable container for your ice tub, you should prepare it for use by cleaning it, sealing holes, and installing drainage.

Here’s how to perform each of these steps:

Clean the Container

Thoroughly clean the inside and outside of the container using a mild detergent and water. This ensures your ice tub is hygienic and safe to use. After cleaning, rinse the container with clean water and let it dry completely. Any remaining moisture can affect the adhesion of the waterproof sealant you’ll apply in the following step.

Seal Seams and Holes

Carefully examine the container for any cracks, holes, or seams that may allow water to escape. Pay close attention to the bottom and sides of the container where leaks are generally most common.

Use a high-quality, waterproof sealant to fill any cracks or holes and to seal any seams. Follow the manufacturer's instructions for application and drying time. This step is crucial to ensure your ice tub remains leak-free. An ice tub is useless if it leaks, making this step essential to follow properly. 
With all possible points of leakage sealed, it’s time to install some drainage. 

Install Drainage

We recommend installing a drainage system to make it easier to remove old ice water from the tub. 

Here’s how to install drainage in your DIY ice bath:

Choose a Drainage Method

Decide whether you want to install a drainage valve or a spigot. A valve allows for faster water removal, while a spigot is simpler to install and use.

Drill a Hole

If installing a valve or spigot, carefully drill a hole near the bottom of the container. The hole should be slightly smaller than the valve or spigot to ensure a snug fit.

Install the Valve or Spigot

Install the valve or spigot according to the manufacturer's instructions. Use plumber's tape or silicone sealant to create a watertight seal around the connection.

Test for Leaks

Before filling your ice tub with water, test the drainage system for leaks. Fill the container with a small amount of water and check for any drips or leaks around the valve or spigot. Make any necessary adjustments to ensure a watertight seal.

Now that your ice bath is watertight and has drainage, it’s time to insulate it to retain temperature.

Step 3: Insulate the Container (Optional)

Insulating your ice tub helps maintain cold temperatures for longer, reducing the need to add ice constantly. While optional, insulation can significantly improve the efficiency and convenience of your homemade ice tub.

Here’s how to insulate the container, starting with choosing the right insulation material: 

Choose an Insulation Material

Several materials, including foam boards, reflective bubble wrap, and spray foam insulation, can effectively insulate your ice tub.

Here’s what to expect with each type of insulation:

Foam Boards

Rigid foam insulation boards, such as polystyrene or polyisocyanurate, provide excellent thermal insulation. They are lightweight, easy to cut, and can be attached to the exterior of your container using adhesive or mechanical fasteners.

Reflective Bubble Wrap

This insulation material consists of a layer of bubble wrap sandwiched between two layers of reflective foil. It helps reflect radiant heat and provides an additional layer of insulation. Reflective bubble wrap is flexible and can be easily wrapped around your container.

Spray Foam Insulation

Spray foam insulation, such as polyurethane foam, can be applied directly to the exterior of your container. It expands and hardens, creating a seamless insulation layer. Spray foam is highly effective but requires more preparation and care during application.

Consider the pros and cons of each carefully before choosing your preferred insulation method. 

Install the Insulation

Once you've chosen your insulation material, you’ll need to measure and cut the insulation, attach it to the tub's exterior with the proper adhesion method, and seal any gaps.

Here’s how to install the insulation for your ice tub:

1. Clean and dry the exterior of your container thoroughly to ensure proper adhesion.
2. Measure and cut the insulation material to fit the sides and bottom of your container. If using foam boards, score the material with a utility knife and snap it along the scored line for a clean break.
3. Apply the insulation to the container using the appropriate method for your chosen material. For foam boards, use a compatible adhesive or mechanical fasteners. If using reflective bubble wrap, secure it with adhesive tape or straps. When applying spray foam, follow the manufacturer's instructions and wear protective gear.
4. Seal gaps or joints between insulation pieces with tape or additional insulation material to create a continuous layer.
5. If desired, you can cover the insulation with a protective layer, such as a tarp or plastic sheeting, to prevent damage and improve the appearance of your ice tub.

With the ice tub built, you can now fill it with water and ice. 

Step 4: Fill the Tub with Water and Ice

Now that your ice tub container is prepared and insulated, it's time to fill it with water and ice, but not before you choose the right location

Here’s how to fill your tub with ice and water:

Choose a Suitable Location

Place your ice tub container in a level, convenient spot. Consider accessibility, proximity to a water source, and drainage options. Ensure the surface beneath the container is stable and can support the weight of the filled tub.

Fill the Tub With Cold Water

Use a garden hose or a large container to fill your ice tub with cold water. If your tap water isn't cold enough, add ice to lower the temperature as you fill. Leave some room at the top of the tub for additional ice and water displacement when you enter the tub.

Check the Water Level

The ideal water level depends on your height and preference. A good rule of thumb is to fill the tub so the water reaches your chest when seated. This allows total immersion of your torso and lower body while keeping your head and neck above water.

Test the Drainage System

Before adding ice, double-check that your drainage system is functioning properly. If using a valve or spigot, open it briefly to ensure water flows out smoothly. This will prevent unexpected issues when it's time to drain the tub after your ice bath session.

Add Ice

Once your tub is filled with water, it's time to add ice to achieve the optimal temperature for cold water immersion. The most convenient option is to purchase bags of ice from your local grocery or convenience store. 

If you prefer a more cost-effective and eco-friendly approach, you can make your own ice blocks using freezer containers. Large silicone or plastic containers work well for this purpose. Fill the containers with water and freeze them overnight or until solid. Pop out the ice blocks and add them to your tub.

Adjust the Water Temperature

The target water temperature for an ice bath is typically between 50-59°F (10 and 15°C). Use a thermometer to check the water temperature and add ice accordingly. If the water is too cold, add warm water to achieve the desired temperature range.

Learn how to do an ice bath at home to maximize the benefits of cold water immersion therapy. 

With your ice tub filled and ready, you're one step closer to enjoying the refreshing and therapeutic effects of a cold plunge in your home.

Step 5: Monitor and Maintain

Regular monitoring and maintenance are key to ensuring your ice tub remains at the optimal temperature and stays clean.

Here’s how to maintain your DIY ice bath for the best results:

Check the Water Temperature

A thermometer is your best friend when maintaining the perfect ice bath temperature. Check the water temperature regularly to ensure it stays within the target range of 50-59°F (10-15°C).

If the water temperature rises above the target range, add more ice to bring it back down. On the other hand, if the water gets too cold, you can add a small amount of warm water to achieve the desired temperature.

Keep the Water Clean

Over time, the water in your ice tub can become murky and unsanitary. To keep your ice baths fresh and hygienic, drain the tub and refill it with clean water every few uses or as needed.

However, if you plan to use your ice tub frequently, consider investing in a water filtration system or a sanitizing solution to keep the water clean and clear for longer periods.

Maintain the Ice Supply

Whether using store-bought ice bags or making your own ice blocks, ensure you have a steady supply on hand. This will allow you to quickly and easily adjust the water temperature as needed.

If you regularly use your ice tub but never have enough ice, an ice maker can be a worthwhile investment. It will provide a steady supply of ice without needing constant trips to the store or the hassle of filling and freezing ice trays.

With your ice tub built, you can now start taking advantage of the many benefits of these awesome recovery tools. However, making your own ice bath at home is not without its challenges, as there are numerous difficulties that you might face during this lengthy process. 

Considerations and Challenges of a DIY Ice Tub

While building your own ice tub can be exciting and rewarding, there are several potential downsides to consider, with leakage, long-term costs, water cleanliness, and overall aesthetic appeal being just some.

Here are the biggest challenges you’ll face when making a DIY ice tub:

Leakage

One of the primary concerns with a homemade ice tub is the risk of leakage. Even with careful construction, time may take its toll on the ice tub. Extensive use can cause damage over time, which may lead to leaks developing, and even small leaks can cause great damage to the surrounding area of your home.

Costs and Ice Requirements

Although initially seeming cost-effective, the ongoing expense of purchasing huge quantities of ice regularly can add up. Even if you make your own ice with an ice maker or freeze large water blocks, both will cost you electricity. 

It may seem counterintuitive, but purchasing a purpose-built ice bath is likely more cost-effective in the long run. The IceBath is an affordable yet advanced model to consider. 

Aesthetic Appeal

A DIY ice tub may lack the aesthetic appeal of a professionally manufactured product. No matter how much work you put into it, it’s likely never going to come close to the professional look of a purpose-built ice bath such as those from Icetubs. 

Although a visually unappealing ice tub may not be a deal breaker for everyone, having professional equipment certainly helps add a little sophistication to any area. 

Water Replacement and Purification

Without built-in purification systems, the water in a homemade ice tub needs frequent replacement to maintain hygiene standards. 

This can become a tedious and time-consuming task, detracting from the convenience and enjoyment of the ice bath experience. However, something like the IceBarrel has built-in purification systems, thus completely eliminating this problem. 

Condensation and Insulation

Improper insulation affects the ice tub's efficiency, especially in warmer months, and can also lead to condensation. This moisture accumulation can create puddles around the tub area, posing a slip hazard and requiring additional maintenance over time. This is an issue that you won't be faced with if you purchase a professional ice bath. 

Final Thoughts

Building your own ice tub is a practical and affordable way to benefit from cold water immersion therapy at home. Following the steps listed above is relatively cost-effective, and it gives you a project to work on. 

However, if you’re looking for something a little easier, more durable, and more reliable, Icetubs offers the perfect solution for those looking to start their cold therapy journey without the hassle of DIY setups.
