Looking for an inflatable cold plunge that can double as a hot tub? Meet the Edge Tub by Edge Theory Lab.

In 2024, cold plunges are the talk of the biohacking world, and for good reason. The practice of cold water immersion (CWI) has been around a long time, but it wasn’t until recently when it went mainstream. Celebrities, influencers, and athletes swear by it – promoting cold immersion as part of their daily routines.

Ever heard of Wim Hof, The Iceman? This legend has inspired millions around the globe with his methods of breathwork and cold exposure. He’s practically the poster guy for this chilly trend, and he’s inspired the guys at Edge Theory Labs too.

There are many cold tub products out there, ranging from DIY ice baths and glorified trash barrels to chic cedar tubs. However, up until now, there hasn’t been a solution appealing to the masses. Enter the Edge Cold Tub by Edge Theory Labs.

Over the past 3 years, I’ve tested out over 25 different brands of cold plunges, and Edge Theory Labs’ tub is a standout. It’s comfy, portable, and easy to use, which is why I use mine everyday. Without further ado, here’s everything you need to know about this inflatable cold plunge. Let’s dive into my Edge Theory Labs review in 2024.

Choosing your Edge tub: know the different options

A few months back, Edge Theory Labs designed a new and improved model – which is different from the classic Edge Theory cold plunge that they previously sold. So today, you have a choice between two cold plunges: The Edge Tub Elite and the Edge Tub Legacy.

When comparing the Edge Tub Elite and the Edge Tub Legacy by Edge Theory Labs, it’s clear that both are designed with the modern wellness warrior in mind, but they cater to different needs and preferences.

I own each of these tubs, so I’ll include my thoughts throughout this article. Here’s a breakdown of what each has to offer below.

Edge Tub Elite:

  • Price: $5,490.00
  • Power: Boasts a 1HP chiller, the most powerful in its class, cooling water to 37 degrees or heating it to 104 degrees in just 2.5 hours.
  • Size Options: Available in standard or XL for full body immersion up to 7 feet tall.
  • Portability: Sturdy and inflatable, designed for both permanent installation and portability.
  • Functionality: Offers both cold and hot functionality, perfect for diverse therapy needs.
  • Special Features: Includes a state-of-the-art filtration and sanitation system, Wi-Fi-enabled chiller for remote control, and is compatible with the Legends circle app.
  • Other note: For an addition $500, you can purchase the Edge Tub Elite Commercial unit, which comes with a commercial grade compressor and 3x sanitizer kits (with extra filters)

Edge Tub Legacy:

  • Price: $4,490.00
  • Power: Features a 0.8 HP chiller, lighter and weighing 25% less than the Elite model, cooling water down to 37 degrees in 5 hours.
  • Size Options: Available only in standard size, suitable for individuals up to 6’4”.
  • Portability: Emphasizes lightweight design for even easier maneuverability and transport.
  • Functionality: Focused on cold functionality, making it a dedicated choice for cold water therapy.
  • Special Features: Shares the Elite’s filtration and sanitation system and Wi-Fi-enabled control, ensuring clean water and convenient temperature management.

Both models are celebrated for their portability, durability, and ease of setup. They come with a 30-day money-back guarantee, a 1-year manufacturer warranty, and access to top-notch customer support. They’re trusted by professional athletes and wellness enthusiasts alike for their quality and performance.

Choosing between the two:

  • Elite is your go-to for more power, faster temperature changes, and both hot and cold therapy options. It’s ideal for those who want the ultimate flexibility and have a bit more space and budget.
  • Legacy is perfect for those focused solely on cold therapy, looking for a more affordable and even more portable option without needing the quickest temperature change or extra-large size.

Both the Edge Tub Elite and Legacy promise a transformative experience in recovery and performance, making them stellar choices for anyone serious about their wellness journey. I’ll discuss more nuanced details of each later in this Edge Theory Labs review, when I discuss the specs and pros/cons.

Edge Theory Labs at a glance

Based in San Diego, California, Edge Theory Labs is a rising star in the cold plunge world. It was founded by cousins Joshua and Rob Church, these guys are all about personal growth and the magic of cold-water therapy.

I met Joshua at an Iceland retreat last winter and was blown away by his knowledge of cold immersion. Like me, he’s made cold dips a daily ritual. It was inevitable he’d channel his passion into something we can all use to boost our lives.

How Edge Theory Labs’ cold plunge is answering market demand

Cold plunges are all the rage, and for good reason! Cold immersion offers countless scientific benefits, ranging from muscle recovery to boosting the immune system. As such, it’s no wonder that cold plunges are gaining popularity across the world.

Sure, you can jump into a trash barrel or chest freezer full of ice. But why settle for a makeshift ice bath when you can have the real deal?

With its flagship products, The Edge Tub Legacy and Edge Tub Elite, the company is answering the market’s growing demand for portable cold tubs. While other tubs might set you back $10,000-$15,000, the Edge Tub offers top-notch quality and durability for just $4,490. It’s a game-changer in the cold plunge market.

Their motto is that “greatness happens at the edge of your comfort zone” and that’s exactly where The Edge Tub takes you. Dive into icy waters, find your edge, and push past it.

My experience using the Edge ice bath

Before jumping into all the specs and other details about the Edge Labs cold tub, let me share a bit about my time with it.

Before getting the Edge Tub for my home, I used it about 5 or 6 times. Right away, I was struck by its comfort and how simple it was to set up. Plus, it’s inflatable and portable, so no need for a moving crew to lug it around!

At a retreat in Mexico, 13 of us shared the tub under the blazing sun, and guess what? The water stayed refreshingly cold for ages. That’s when I knew I needed one at home.

My experience owning two Edge Tubs

For many businesses, the relationship ends the moment you receive the product. This is a totally different story with Edge Theory Labs.

In my experience, ETL really knows how to treat you right. Once my tub landed at my doorstep, the real fun began. I got a handy email with a link to their mobile app, where I could mingle with fellow cold plungers and catch online events. They even sent a 7-minute video that had me set up in under 10 minutes!

I firmly believe in the power of proximity. I used to trek 25 minutes to the gym for a cold dip, but now, with the Edge Tub in my living room, I’m diving in daily. It’s almost too easy!

As of January 2024, I’ve owned the legacy tub for around a year. And just last month, I got the Elite tub as well. I decided to get the XL version, which more spacious and allows me to get my full body comfortably in the tub. It’s such a game changer, especially for me as a tall person at 6’4″.

And let me tell you, I’ve never felt better – body, mind, soul, the whole deal. My performance at work and at the gym has never been better – I am truly living life to the fullest, in part thanks to this product.

Those chilly winter mornings are tough, but the boost I get is unbeatable. Ready to hear about the cool features of this inflatable wonder? Here we go!

Highlights of using the Edge Tub

Priced between $4,490 and $5,490 depending on which model you get, The Edge Tub is a significant investment. As such, it’s most suitable for people (and organizations) who practice cold immersion regularly. If you’re new to cold plunges, you’re better off starting with ice baths in your bathtub or cheaper models before working up to this one.

Here are some things I find most unique and interesting about The Edge Tub:

– The Edge Cold Tub has an ergonomic design that allows you to sit comfortably inside. The standard size is 47 inches long, 25 inches tall, and 24 inches wide. I’m 6’4” and I can fit well in a reclining position with my knees bent.

– It can be used as a hot tub and a cold tub. The 1.0 horsepower compressor in the Elite Tub can cool the tub to 37°F (2.8°C) and heat it up to 105°F (40.6°C).

– The tub contains an advanced filtration system that fully renews the water every 15 minutes. This makes it clean and suitable for gyms and wellness spas with high-volume usage.

– Unlike many other tubs and pools out there, The Edge Tub uses an EPA-approved, non-chlorine sanitizer that is clean and safe.

– Though the Edge cold plunge is inflatable, you wouldn’t know it by how sturdy it is. The tub uses military-grade technology and has the same material as inflatable paddleboards and boats.

– You can adjust the chiller settings remotely using a smartphone application on your phone. All you need is a Wi-Fi connection to toggle between warm/cold settings.

– The Edge Tub weights 25 lbs. and fits in a backpack. This makes it one of the most portable cold tubs out there.

– People who are new to cold immersion and don’t know if they want to do it long term

– Folks looking for a budget cold plunge tub are better off with a cheaper alternative on Amazon

– Those looking for a freestanding tub rather than an inflatable one may opt for an alternative to the Edge cold plunge

My tips for using the Edge ice bath

1. Position Your Body for Maximum Impact: The Edge Tub has plenty of space, so be sure to bend your knees (if needed) to submerge your body up to your neck. This will allow your Vagus nerve, the most important component of the parasympathetic nervous system, to reap the anti-inflammatory benefits of cold plunging.

2. Best time of day to use the Edge Tub: You can’t go wrong with an Edge cold plunge anytime of day. However, I like to start my day with a polar plunge to get a boost of energy and focus. It’s also great to use before bed, as it leads to a feeling of relaxation and calm.

3. Add ice to bring cold plunge temperature to 32°F: The Edge cold plunge has a built-in cooling system that brings the temperature down to 37°F. If you’re someone who wants to make it colder, add a bag of ice cubes. It’s safe to do so and it will give you that Wim Hof ice bath experience you’re looking for.

4. Take advantage of built-in financing options: The Edge Tub offers financing through Affirm for as low as $174/month. If you qualify for 0% APR, definitely take advantage of this. Given that this is a pricey product, having a 0% loan with no credit check can help make this product significantly more affordable.

5. Do a head dunk for added effect. It goes without saying that you should put your arms and hands in the water. But I also recommend dunking your head under for just a few moments. Be sure to do this in a safe way though, and it’s always a good idea to have someone spotting you while you’re in the tub.
