Renu Cold Plunge Review: Is The Cold Stoic 2.0 Worth It?

Trying to decide what cold plunge to buy is daunting.

First, everyone seems to have a strong opinion, there are also more brands than you could imagine, anddddd they all have significantly different features and benefits.

So how the heck are you supposed to choose one?

Not only choose one, but not regret it. After all, some of these tubs can go up to $25,000.

Yup, the price of a used car.

To eliminate the guessing game and avoid buyer’s regret, I’ve made it my mission to research and simplify this process for you.

Bringing it back to the topic of discussion – the Renu Cold Stoic 2.0 has been popping off lately.

The real question is – is the Renu Cold Stoic 2.0 worth the investment? Are its competitors superior? Or are you better off with a cheaper tub that gets the job done?

Let’s dive into this Renu Cold Plunge review!

Is The Renu Therapy Cold Stoic Worth It?

Let’s be real – cold water immersion is not for the faint of heart.

It takes commitment and dedication to make regular ice baths part of your routine.

If you’re new to cold plunging, I’d recommend starting with some affordable ice bath sessions first, DIY cold plunge, or a cheap inflatable ice bath to see if it’s something you’ll stick with.

Once you know you are committed or are already a seasoned cold therapy junkie, then let me assure you – investing in the Renu Cold Stoic 2.0 is a decision you won’t regret.

The product itself is great (It should be for a $10,000 price tag), but it comes down to you. What is your level of commitment, experience, and budget?

For example, if you need to purchase a car and you are presented with a Rolls-Royce (or Renu Cold Stoic 2.0), the car is a masterpiece, with top-of-the-line pieces, design, and price. Is it worth it? Well, it really depends.

But, personally, the fact that I don’t have to hassle with ice bags, the water not being the ideal temperature, corrosion, cleaning the tub, or stressing that the tub will break and I’ll lose my investment already makes it worth it.

But, it is a pretty big investment.

So, you get to define your specific needs and non-negotiables. To make it a little bit easier.

Let’s break down the categories of who may or may not want to purchase this tub.

  • Cold plunge enthusiasts (people practicing the Wim Hof method or who are just committed to cold therapy) are looking for an extremely optimized ice bath.
  • Gym/ spa owners who are looking for a premium, durable cold plunge tank as an added benefit to their customers.

  • Gym-goers or athletes who are ready to invest in the health benefits of cold therapy (decreased inflammation, better muscle recovery, and increased performance.)

Not Recommended For

Renu Therapy Cold Stoic 2.0: The Drawbacks

  • Heavy (Not portable)
  • Expensive
  • Long shipping time
  • You will have to get a group of people to get the bathtub inside your home

The Renu Cold Stoic 2.0 comes with a few drawbacks to consider.

Firstly, it has a heavy and bulky construction that makes portability difficult. The high price tag of close to $10,000 is a significant investment. Customers also report long lead times for shipping the cold tub. Once delivered, you’ll need multiple people to maneuver the tub inside your home due to the large size and weight. Other possible downsides are the energy usage of the integrated chiller and the need for sufficient clearance space for the tub.

Carefully measure your space and assess your budget to determine if the Cold Stoic 2.0 will realistically work for your needs.

Amazing Warranty:

Most cold plunge tubs on the market have significantly shorter warranty periods, often 1-3 years at most. The Renu Cold Stoic 2.0 stands out with its generous 5-year warranty (excluding the chiller and commercial use). This extended coverage period gives me confidence and assurance for such a major investment. To me, it signals Renu’s faith in the tub’s durability and longevity.

Versatility and Customization Options

I love that you can customize the tub. Many cold plunges out there frankly look ugly – just a block of metal and wood slapped together. With Renu, this is not the case.

You can even customize the tub to match the color of wherever you will be using the cold plunge. The tub has a very sleek and modern look with a beautiful shine and coating.

You can select colors and materials to seamlessly match your existing space and style. Options include hues like Meteorous Black, Bianco Roman Granite, Basalt Grey, and luxurious wood types like California Redwood.

On top of this, you will have to pay extra, but you can pay for underwater lighting. Which isn’t necessary, but honestly looks pretty sick.

Low Maintenance 

This plunge is made for seasoned cold plungers. So, it’s safe to say this is an optimized tub. The cold stoic 2.0 from Renu comes with a high-quality 1/4 HP water chiller that can set the water temperature to 36 degrees.

What does this mean for you?

Well, you don’t have to be hassling with ice cubes or constantly having to change your water-less work.

The tub also comes with an integrated 2-stage filtration system and ultraviolet ozone generator. Why should you even care? This does the heavy lifting when it comes to making sure your water stays clean, microbe and debris-free. You won’t have to constantly clean the tub, replace the water, or deal with some nasty smelling and looking water.

Customer Experience

Renu is celebrity-backed by athletes like MMA fighter Yoel Romero and famous actors including Rainn Wilson. But perhaps more telling are the overwhelmingly positive customer reviews. Outside of their website, people generally rave about the Cold Stoic 2.0 experience (could find zero negative reviews a  the time of writing this).

Financing Options

This tub lays right around the 10k mark. So, what do you do if you want to invest in this tub but don’t ly want to pay everything upfront? They offer a nice payment plan.

Renu uses Affirm to offer different types of payment plans. 6, 12, and 36. The 6-month is the only one that offers a 0 APR/ interest rate.

Honestly, at the 36-month mark, it may not be worth it for you as you will be paying a 15% APR totaling a whopping extra $2,404.95. At checkout, you will also have the option to use a traditional credit card, Coinbase, PayPal, Meta Pay, or Shop Pay. 

Best Cold Plunge Tub Alternatives:

Look, the Renu Cold Stoic 2.0 is a beast of a cold tub. But it ain’t for everyone. With so many ice bath options out there, you gotta shop around before dropping 10K.

What you need depends on your budget, space, and how hardcore you go with cold therapy. Brands like Ice Barrel provide quality without wrecking your bank account.

There’s no shortage of Renu vs Blue Cube vs Morozko vs Edge Theory comparisons out there. Honestly, none are totally wrong.  All of these tubs are popular for a reason, they are amazing!

But, for different people and different needs.

So here are a few cold plunge tubs that vary in price, design, and features that I personally like a lot:

And you can always try cheaper ice bath tubs, DIY tubs, or cold showers if you wanna test the ice bath waters before investing big. Gotta find the cold plunge that fits your lifestyle!

Dimensions:  2.5/50

Quality: 5.0/5.0

Durability: 4.0/5.0

Pricing/Pricing Plans: 1.0/5.0

After reviewing all the details, it’s clear the Renu Cold Stoic 2.0 is a top-tier cold plunge tub for devoted cold therapy enthusiasts.

While the nearly $10K investment is substantial, the unparalleled quality, customization, and convenience features make it worthwhile for serious plungers.

However, more casual users or those new to cold immersion may be better off starting with a more affordable DIY tub or inflatable option before committing. And alternatives like the Blue Cube provide luxury and innovation at lower prices.

Ultimately, evaluate your budget, space constraints, and commitment to daily cold plunging. For hardcore ice bath lovers with the resources, the Cold Stoic 2.0 is a smart splurge that optimizes the experience.

More occasional plungers can likely find adequate options for less cost.
