Building a Backyard Oasis
with a Cold Plunge Tub
Have you seen people immersing themselves in ice-cold water and wondered why they're so keen on a teeth-chattering experience?
Well, this modern-day trend isn't just a passing internet challenge but a time-honored tradition in Nordic cultures that has been practiced for centuries to promote well-being.
From enhancing immune response and improving circulation to potentially enhancing mental health, the list of cold plunges’ health benefits is as long as it is impressive.
Read on to learn about the fascinating history of cold water immersion, its benefits, and different ways to incorporate it into your routine.
Introducing Cold Plunges
A cold plunge is an immersion in water that’s around or below 50 to 59 degrees Fahrenheit. While most people believe this cold therapy to be a relatively new thing, it dates back to 3500 BC when Roman physicians used to prescribe it for treating a variety of ailments such as skin issues, high fever, and open wounds.
However, it was not until the 19th century that the practice gained scientific interest and wider acceptance worldwide. These days, cold water immersion has evolved into a favored wellness ritual for awakening the senses, recharging the mind, and increasing energy levels.
Cold Plunge Working Mechanism
When you immerse your body in cold water, you induce an acute stress response that triggers a series of physiological responses. Initially, the cold water sends your body into a state of mild shock that activates your sympathetic nervous system, increases your heart rate, and causes hyperventilation.
Sudden cold exposure also constricts blood vessels, helping redirect blood flow from the skin and extremities to protect vital organs and maintain core body temperature. As you pass that initial stage and adjust to the temperature, you start reaping the benefits associated with cold water immersion.
Cold plunges can be done in various ways, such as taking an ice bath at home or jumping into a chilly lake during winter months. However, cold plunge tubs such as Dundalk Leisurecraft Baltic Plunge are one of the most controlled and convenient ways to engage in this practice. These specialized tubs allow you to regulate the water temperature to your preferred settings, making it easier to start with milder temperatures and gradually build your tolerance over time.
Some cold plunge chillers, like Aquavoss Model 2, even come with a Panasonic compressor that helps maintain the desired temperature for longer durations, so you don’t have to worry about adding buckets of ice. The included high-velocity hydrotherapeutic massage jets soothe every knot and tension in your muscles, providing an unparalleled recovery experience.

Benefits of Using a Cold Plunge Tool
The following are some of the benefits of cold plunges:
-
Research shows that cold water immersion increases metabolic activity and stimulates the production of leukocytes and other immune system cells that fight off disease and infection.
-
Ice baths also help shrink your pores and reduce skin inflammation, making your skin look smooth and fresh.
-
Regular exposure to cold water is also known to increase the efficiency of the body's autonomic processes, such as breathing and heart rate, which can improve resilience to stress and disease.
-
Research demonstrates that cold plunge stimulates the release of different neurotransmitters, such as beta-endorphins, noradrenaline, and dopamine, that help improve concentration, uplift mood, and induce pleasure.
-
A 2018 study further reveals that cold hydrotherapy can reduce depressive symptoms and anxiety.
-
Studies explain that cryotherapy helps reduce muscle breakdown and swelling, flush out lactic acid, and aids in post-exercise fatigue recovery, making it beneficial for athletes.
How to Use a Cold Plunge
Taking the cold plunge doesn't have to be an ordeal. Here’s a straightforward guide to making the experience both beneficial and bearable:
-
Ensure your cold plunge chiller is filled with water and chilled to the recommended temperature, usually between 50 to 60 degrees Fahrenheit.
-
Since sudden exposure can be life-threatening, step slowly into the tub to avoid any issues.
-
Once you're in, submerge yourself up to your neck. For beginners, one to three minutes is sufficient. As your tolerance builds, you can extend this time.
-
Your body’s first reaction will be to hold your breath. Instead, breathe deeply. It helps stabilize your heart rate and trick your mind into calming down.
-
When inside, pay attention to your muscles and keep moving them to improve blood flow.
-
After a cold plunge, your body will be a bit numb. Exit the tub slowly to prevent any light-headedness.
-
Allow your body to warm up on its own. If possible, engage in gentle movements or some light stretching to facilitate this process without further shocking your system.
To enhance the experience, consider the Nordic cycle, which involves alternating between hot and cold baths. The easiest way to practice this contrast therapy is to spend 15 to 20 minutes in a hot sauna, followed by one to three minutes in the cold plunge. This rapid temperature change helps invigorate the body, improves circulation, and may aid in muscle recovery.

I haven't even built this sauna yet (Rainelle), but I have to give an ENORMOUS shoutout to Adora and especially KELLY for their help on this one. This was a big purchase for us, and these ladies went way out of their way to make it work out for us. The first sauna that showed up was badly damaged in shipping, and from what it sounds like - that is not typical. At all. So Kelly helped us to get it squared away, and it took what could have been a horrible customer experience into a fantastic one. Give this woman a raise!
We really like our sauna! Quality of the sauna seems decent. The quality of the accessories was not! The back recliner was all busted up out of the box.
My wife and I would occasionally sit in the sauna at our gym after a workout. It was hot but a little gross. I can't tell you how many times we bailed on the gym sauna session because someone else was playing their phone too loud, someone was breathing like they were gasping for air, someone decided to be shirtless in public, someone is weird or any number of other reasons. Loved the sauna feeling but HATED the gym sauna.
We bought a sauna for our home and installed it in our basement to escape the gym sauna experience. We absolutely love it! We sauna daily. Without the angst and frustration of hoping to avoid an awkward gross experience at the gym sauna.
If you are considering a sauna purchase, spend a little extra and get the WIFI enabled heater. This is the best way to make sure you get the benefit of owning a sauna. The app on our phone is easy to use. Just click the on/off button on the app and set your temperature to your desire. I like 171. My wife likes 153. Once it hits the temperature, the app will let you know. You can even turn on your sauna while you are on the way home from the gym. The WIFI version and the app make all the difference in usability and enjoyment of your investment. If we did not have the app and the WIFI version, we probably would probably skip 2/3 of the sessions we currently take.
The sauna is well made. Wood quality is excellent. Very few knots and blemishes. Hillsboro Almost Heaven saunas are a great choice for quality components, solid electronics, easy to use controls and an enjoyable sauna experience.
This is a standard kit sauna. I made several modifications but I am very satisfied with it so far. I have a few shingles left to install tomorrow and then will move onto to interior. MSW has been easy to work with and I recommend them.
I really love this sauna. I use it about four times a week to help me wind down before bed and calm my ego. Customer service at MySaunaWorld was great.
Assembly took me roughly 8–10 hours total over two days, and I’m not a particularly handy person. The step by step instructions video was straightforward and easy to follow.
I paired the sauna with the HUUM Drop 9 heater (the largest HUUM Drop), and it performs very well. I hired an electrician to install it (about $900 extra). It easily heats the sauna to 190°F plus. I personally like it around 180°F, which it reaches in about an hour. Also, you can pour water over the hot rocks to make the air hotter and steamier. Make sure to mount it low so that it can heat everything above it. (I mounted mine 6” from the ground to the base of the heater.) I love that I can start heating the sauna from my iPhone, even when I’m not on my home Wi-Fi.
I got the double-bench configuration going across the back of the sauna which lets two people lay down. The area around the lower bench is cooler which is nice to have different temperature seating options.
The sauna looks fantastic, smells great, and feels solid. I would recommend this sauna to a friend.
We love our new Almost Heaven Pinnacle barrel sauna!
Delivery was perfect, the assembly was a breeze, and the sauna fits perfectly in our space.
The only regret we have is not to have made this purchase 10 years ago!
I had been thinking about installing a sauna for quite some time. I kept going back and forth between framing one in or a prefab that I assemble. I spent several weeks going over the various websites looking at designs for both and writing out the pros/cons for each. After much deliberation, I reached out to My Sauna World to purchase an Almost Heaven Greyson.
It came way sooner than expected which was a good thing, so I had to arrange for my electrician. I assembled it very easily, with my wife holding just one panel, and then I ran into a problem. The last wall was short. It took a lot of head scratching and measuring and remeasuring as well as back and forth communication with both My Sauna World and Almost Heaven. It turned out that I had been sent 2 glass panels that were the same dimension when the 2 glass panels are actually designed with different dimensions. The new panel was sent out without question, and the rest of the assembly went easy.
I will say that the folks at My Sauna World were extremely responsive and did a great job as liaison back to the manufacturer.
Overall, I had a really positive experience, and we are very happy with the Greyson with the Harvia Spirit 8kW stove.
We also have the duckboard flooring (that is a must) sitting on top of the concrete floor. The back and leg rest are also recommended.
Note: this is advertised as a 3-4 person but in reality it is a good 2 person. And lastly, I grew up with sauna my whole life, starting with my grandpa’s wood burning sauna. This non insulated Greyson type will not get up to the same temperatures, but it does get the job done. Very pleased with the product and do recommend (to frame one in my self and buy a pre-cut kit would have cost a few thousand more overall)
Their customer service is refreshing in a world where most companies fail miserably with service. They should teach customer service to other companies and government agencies. We have only tested the actual product to make sure it works, but along the way, we had multiple questions and the replies were quick and helpful. The sauna was easy to assemble.
Frankly, I was stunned at the quality of this product. Equally stunning is how easily everything fits together. It’s well and I’m looking to an improved lifestyle.
Back rests are a nice size and fit perfectly in my Lugano 3-person sauna. They are very comfortable (especially considering they are wood) and make sitting in the sauna an even more pleasant experience. To think that they were added in free to my purchase of the sauna is hard to believe. Very pleased with customer service from My Sauna World.com !
Well built, good quality, reliable, and matches my barrel sauna very well
I purchased this since it was significantly more affordable than from the brands website. It arrived quickly and is function perfect. It's easy to install and looks great. I had issues with water leaking into the sauna before that used to annoy me. Now it stays completely dry and the wood also is protected from damage and weathering.
The best Sauna ever, and the quickest delivery, 100% recommend !!!!
Works exactly as advertised. Easy install and perfect coverage. Highly recommend.
Very good customer service. My sauna came as expected.
