As someone who has gone over the bulk of ice bath tubs on the market with a fine toothed come, I understand the importance of finding the perfect product that meets your specific need, especially when spending up big on your cold plunge for home.

With the growing popularity of cold water immersion, it can be overwhelming to navigate the market and choose the right ice bath for yourself.

That's why I've taken it upon myself to review some of the top cold plunge tubs available for sale today, including the highly acclaimed Cold Stoic 2.0 from Renu Therapy. 

Renu Therapy is a renowned brand in the cold tub space, catering to professional athletes, Hollywood celebrities, and everyday individuals who value health and wellness. Their flagship model, the Cold Stoic, offers a premium ice bath experience for those fully committed to the cold plunge lifestyle.

Let's take a closer look at the Cold Stoic 2.0 by Renu Therapy, and stack it up against a few of the other big players in the cold plunge market like Plunge, Ice Barrel, Blue Cube and Morozko Forge.

Within their ice bath tub collection, the Cold Stoic serves as the base model, while the Cold Stoic 2.0 has a few enhanced features for a slightly higher price. There are also a few larger options like the Siberian Cold Plunge for those who need to stretch out or something big enough for 2 people to plunge, as well as recently adding a portable Traveling Stoic option, strays away from the solid, fixed style tubs that Renu started with.

Is the Cold Stoic 2.0 worth it? 

Absolutely! Let me tell you, cold water immersion is not for the faint of heart. Sure, if you haven’t done a lot of cold plunge and this is going to be your first ice bath purchased, it might be worth looking into a bit more before you spend over $10k on a cold plunge for home.

It's a lifestyle choice that requires commitment and dedication. I always recommend people spend a few weeks going to a wellness space that has an ice bath and spend the money on a few cold plunge sessions first to see if cold therapy is something you want at home and would make enough use of for the investment.

If you're already a devoted cold plunger like me, then investing in the Cold Stoic 2.0 is a decision you won't regret. Trust me, it's worth every penny to have the water icy, clean and ready for you and not have to do annoying and time-consuming trips for ice bags – this is just a barrier to a regular cold plunge practice!

It's like having a permanent addition to your property like an infrared sauna, it's a statement piece that enhances your lifestyle and you want to get solid use out of.

With a price tag of $9699USD, you might be wondering if it's worth the investment. Well, let me assure you that it is. The Cold Stoic 2.0 offers a range of customisation options, allowing you to personalize your ice bath experience. And the features? Yeh they have those too. You can customise pretty much every feature in the Renu Therapy Stoic 2.0 including adding an internal night light, choosing the timber colour and the finish colour.

Things To Note About Renu Therapy Stoic 2.0

When you see the Renu tubs, there is no doubting that this is an ice bath for a luxury cold water therapy experience. There are just simply no other ice bath tub brand out there that offers the same level of design and feature customisation, apart from maybe Brass Monkeys, which are an ice bath in UK.

Compared to other brands like Brass Monkeys in the UK, Renu tubs stand out due to their focus on customization. Users can often choose from a variety of sizes, materials, and additional features that cater to specific preferences and needs. Whether it's the integration of ergonomic seating, adjustable water temperature controls, or advanced filtration systems, Renu tubs are designed to provide a tailored cold water therapy experience that meets individual requirements.

Moreover, the construction and durability of Renu tubs are typically of high quality, ensuring longevity and reliability over time. This durability is essential for withstanding frequent use and maintaining optimal performance, whether in a professional sports facility or a private home gym environment. The robust design and premium materials used in Renu tubs reflect a commitment to excellence and customer satisfaction, offering reassurance to users seeking a reliable cold water therapy solution.

Additionally, the aesthetic appeal of Renu tubs contributes to their appeal beyond mere functionality.

No Chemicals required

Cold Stoic 2.0 actually is low-maintenance which is attractive, and there’s no doubt it is miles better than the all too common starting point of converting the household chest freezer. While this is great temperature wise, the safety aspect and the convenience of having clean, filtered, sanitised water are just not there with the chest freezer conversion DIY option.

Renu Therapy’s Stoic 2.0 uses a natural 4-part purification system that uses an ozone generaor, replaceable filter, spa stick and dirt/oil buoy means there is no need for harsh chemicals to be added to your water to keep it clean. 

No Plumbing required

The lack of extra plumbing requirements for the Cold Stoic 2.0 offers a very hassle free setup for most people, and the drainage valve has the ability to link up with a garden hose. Instead, the water flows through the Renu 1/4 HP water chiller which can be set to chill the water temperature down to as low as 36F (2.2C) and can run 24/7. The pump cycles an 20 Gallons every minute and never gets contaminated with harmful oils or chemicals. It also includes a removable large grate that catches larger debris and a flow-through, replaceable 50-micron water filter element for fine particles.

Central to the Cold Stoic 2.0's functionality is the Renu 1/4 HP water chiller, which serves as a pivotal component in maintaining optimal water temperature for cold water therapy. This water chiller is designed to lower water temperatures significantly, capable of chilling water down to as low as 36°F (2.2°C). The chiller operates continuously, ensuring consistent cooling performance around the clock. This capability is particularly beneficial for athletes and individuals seeking precise control over water temperature to maximize the therapeutic benefits of cold water immersion.

Moreover, the Cold Stoic 2.0 incorporates a robust pump system that efficiently cycles 20 gallons of water per minute. This high-capacity pump supports effective circulation within the tub, facilitating even distribution of cold water and promoting uniform cooling throughout the immersion process. Importantly, the pump is designed to remain uncontaminated by oils or chemicals, preserving water quality and ensuring a clean and hygienic user experience with each session.

The inclusion of practical features such as a removable large grate and a flow-through, replaceable 50-micron water filter element further enhances usability and maintenance convenience. The removable grate effectively captures larger debris, preventing clogging and simplifying cleaning tasks. Meanwhile, the replaceable water filter element helps remove fine particles from the water, promoting clarity and cleanliness throughout extended use.

Multiple colour and timber options 

The Renu Stoic 2.0 and the other Renu ice bath tubs offer a massive range of colour and timber choices which we love. For people making choices for a cold plunge tub for home or wellness space, this gives you the selection to match your design and aesthetic closely to make the cold plunge customised to your internal or external space.

When you go through the checkout on the Renu shop for their ice baths, it allows you to first choose your base colour in either Meterous Black, Bianco Roman Granite, Basalt Grey, Sira Grey Granite, Estonian Sandstone, Adriatic Grey and then choose your “breath deck” timber type between California Redwood, Pacific Cedar, Shou Sougi Ban Dark Burn or Shou Sougi Ban Tiger Stripe.

Not only that, you can upgrade the Stoic 2.0 and include a spa light for an extra $320 which offers both red and blue lenses for the ultimate night time plunge experience.

Warranty Period

The warranty on the Renu Stoic 2.0 is exceptional. The 5 year warranty is one of the big selling point for the Renu tubs in my eyes, and offers a confidence element that you know you will be supported with quality and design issues for a long period.

It is worth noting that the warranty only covers for defect that arise during normal use conditions, not for poor water chemistry, neglected filter care, freezing conditions, power outages, lack of attention to low water flow, or any other form of neglect, misuse, or abuse. Keep in mind, the 5 year warranty does not apply to the chiller unit, this only carries a one year warranty.

Frequently Asked Questions

Final Word on Renu Stoic 2.0

The Renu Stoic 2.0 has got to be up there in the top three ice bath tub brands we have reviewed to date. All things considered, the Renu Therapy tubs really do stand up well against some of their main competitors like Plunge, Blue Cube and Morozko. In terms of design and overall quality, I would personally choose the Renu therapy tub over the Blue Cube or Morozko, and the really beautiful design just has way more character than the plain white bath tub style of the Plunge Cold Plunge. 

Overall, I would offer the Renu Therapy Stoic 2.0 a strong score of 4.8/5 in the cold plunge department. The only thing they are really lacking is a powerful chiller unit, at 1/4hp this just isn’t quite as strong as some of the other big player which use a chiller unit 2-3 x stronger than this.

The modern aesthetic, mixed with a very cool selection of timber choices really gets me excited and is definitely what gives the Renu brand a strong edge in the ice bath tub market. Sure, the price is high, but this is no blow up plastic ice bath. This is something you will want to put on display!
