Are you looking for a way to improve your health and well-being? Cold plunges are a fantastic way to reset body and mind. Studies have shown that cold exposure can improve mental performance, reduce stress levels, and even help boost immune system function. Even short periods of cold exposure can cause a lasting increase in dopamine and a sustained increase in mood, energy, and focus. Check out more details in this episode of the Huberman Lab podcast.
I started taking cold showers when I was about four years old. I think it’s something of a family tradition, apparently passed down by my great-grandma. While a cold shower is a good solution, nothing compares to full immersion in icy water. I finally bought a cold plunge last year, and it’s definitely a game-changer. It’s almost as nice as a dip in a wintery Swedish lake (and yes, that’s me in the picture above).
Imagine jump-starting your morning with a cold water immersion-induced dopamine kick or a refreshing dip during a hot day.
In this guide, I ranked and reviewed 7 of the best cold plunges on the market, along with my top 3 choices depending on what features you care most about.

What are the best cold plunges of 2023?
Below I review my favorite cold plunges on the market today. These ice baths have some key features in common that make them convenient and easy to use: water filtration and sanitization, as well as efficient cooling with good insulation. I do not include any plunge pools that are essentially a barrel you must fill with ice on your own as this is something you can replicate in your bathtub almost for free.
Renu Therapy – for the designer look
The Renu cold tubs feature an elegant yet super tough exterior with a wooden top that can be placed indoors and outdoors. The self-contained system chills water temperature down to 36°F (2.2°C) and includes advanced filtration systems and ozone purification to keep the water clean. It also comes in several sizes and color options.
- Temperature: Cools the water to 36°F (2.2°C)
- Size options: You can choose between the Cold Stoic standard (suitable for customers up to 6’5” and/or 255lb), the Cold Stoic 2.0 (up to 6’7” and/or 275lb), and the Siberian Cold Plunge, suitable for plungers 6’8” and/or 290lb and over.
- Base colors: Depending on the model, you can choose between five or six base colors.
- Wooden deck: The top wooden deck is also available in several alternatives. For a natural wood look, choose between the California Redwood and Pacific Cedar options that are treated with all-natural tung oil and wax. For a more artistic look, go for the Douglas Fir finished using the Shou Sugi Ban technique – a traditional decorative Japanese wood preservation technique through burning. The wood is torched and repeatedly scraped to create a more waterproof and weatherproof surface with an artistic look and exposed texture.
- Equipment enclosure: All the equipment is enclosed and out of sight, keeping it safe and ensuring an aesthetically pleasing experience. The enclosure additionally reduces noise pollution from the chilling system.
- Water sanitization: The plunge sanitizes the cold water using ozone technology and a filtering system.
- Insulated cover: All Renu plunges have an insulated cover that helps maintain cold temperatures and a matching step stool.
- Warranty: A 5-year limited warranty is included
- Shipping: Free shipping on all cold plunges
- Made in the US
The Cold Stoic starts at $9,699, and the larger Siberian Cold Plunge starts at $13,899. If you choose a deck finished using the Shou Sugi Ban technique, it’s $500 extra. A spa light can be added for $319.
The Renu Therapy ice bath is a piece of art that stands out among other cold plunge pools. I also like that the cooling mechanism is out of sight. This is my choice if you want to spend the extra money.

The Morozko ice bath is the perfect option for those who keep their ice plunge outdoors and live in cold climates and those looking for the added chill of cold therapy amidst floating ice.
Polar Monkeys The Portal – For the Budget-Friendly Option
This cold tub from Polar Monkeys is a no-nonsense ice bath with everything you need to immerse yourself in cold water without the glamorous features of some of the other ice baths. This simplicity is also reflected in the price.

I am a big fan of the Polar Monkeys cold plunge pool. If you want to start practicing cold water exposure but don’t want to pay for “extras” such as a fancy wooden exterior and hidden cooling mechanism, this is the best ice bath for you.
This handmade cedar ice bath on this list can reach temperatures as low as 32°F (0°C). It features a unique cooling mechanism in which the cooling compressor is connected to copper coils wrapped around the inner stainless steel tub walls.

This is a really cool (no pun intended) looking ice tub, and it’s nice that it’s self-contained and you don’t see the cooling mechanism. Note that the Odin ice bath should be placed without direct exposure to the elements.

This is a great option if you want a weather-resistant tub that can be used outdoors. The insulation on the underside of the tub ensures that you won’t have to deal with condensation should you choose to use it indoors.

The Dreampod Barrel – For the Small Footprint
Dreampod makes a barrel ice bath – the only one I could find with such a small footprint. This is ideal if you want to enjoy a regular freeze but don’t have the luxury of tons of space.
- Temperature: Cools to 37°F (2.8°C)

This is an interesting option if you’re tight on space, and it is suitable for indoor and outdoor use.
What is a cold plunge?
A good cold plunge maintains filtered and sanitized water between the temperatures of 32°F (0°C) and 39°F (3.9°C). Cold water immersion provides mental and physical benefits, such as reduced inflammation and increased blood circulation, which promotes relaxation, alleviates pain & anxiety, and enhances focus & cognitive abilities.
Summary – what is the best cold plunge of 2023?
Check out the table below for a summary of the best cold plunge options. I recommend considering a few things before buying one: will you have it indoors or outdoors? If you plan to have your cold plunge outdoors and live in a climate where temperatures fall below freezing in the winter, you may want a plunge with good insulation to withstand cold temperatures without the pump mechanism freezing. Otherwise, you may have to disconnect it and empty the hoses or add hot water to it regularly. If you plan to have it indoors, either make sure you can place it on a waterproof floor or buy a cold plunge that does not condensate.
