What to Look for in a Cold Plunge Tub

Choosing the right cold plunge tub comes down to understanding what matters most for performance and comfort. Here are the key factors we consider:

• Temperature range: Look for tubs that can cool to at least 37°F (3°C) for effective therapy. Some also offer heating for contrast sessions.
• Cooling speed: Faster chillers mean less waiting time and no need for ice.
• Filtration and cleaning: Built-in filters and sanitation systems keep water clear and low-maintenance.
• Size and footprint: Make sure the tub fits your space, whether indoors or outdoors.
• Noise level: Quieter models are better suited for home gyms or indoor use.
• Smart features: Wi-Fi and app controls add convenience for adjusting temperature remotely.
• Safety: Look for features like automatic shut-off, warnings, and solid construction.

Top Cold Plunge Tubs of 2025 (Expert Picks)

We tested and researched the most talked-about cold plunge tubs of 2025, including established leaders and innovative newcomers. Here’s our take on the best cold plunge tubs this year.

Empava Cold Plunge Tub (Our Top Pick)

Empava’s Cold Plunge Tub is the most exciting launch of 2025. It combines advanced cooling power (3 kW) with a sleek, spa-like design perfect for home gyms or wellness rooms. Its 3–30°C (37–86°F) range supports both cold therapy and contrast sessions without ice. Wi-Fi connectivity and app control make it easy to adjust settings from anywhere.

We love its quiet operation (68 dB) and built-in filtration, which keeps maintenance simple. Automatic heating and cooling modes further elevate convenience. This tub feels like a true step forward. It is modern, tech-friendly, and built for daily use.

Ideal for: Users who want a high-end but low-maintenance plunge tub with premium performance and style.

Sun Home Cold Plunge Pro – Best Luxury Option

The Sun Home Cold Plunge Pro remains a strong contender in 2025. It chills water down to an impressive 32°F, which is ideal for those who want ultra-cold immersion. It also features durable construction, integrated filtration, and app-based control. Hence, it is a well-rounded premium option.

However, it’s large and heavy. So, it requires more space and investment than newer, more compact designs.

Ideal for: Serious cold therapy enthusiasts seeking professional-level performance at home.

Hydragun Supertub – Best Portable Design

Weighing just 21 lbs when empty, the Hydragun Supertub is lightweight and inflatable. It’s easy to set up and pack away. So, it is great for small spaces or travel. Its chiller cools quickly, and the sturdy build feels surprisingly durable for a portable tub.

That said, it lacks the deep temperature range and tech features of fixed models like Empava or Sun Home.

Ideal for: Users who want a flexible and portable plunge solution with fast setup.

Desert Plunge Grizzly Wide 450 – Best Outdoor Build

Holding 112 gallons of water, the Desert Plunge Grizzly Wide 450 is designed for rugged outdoor use. The built-in chiller cools to 39°F. This eliminates the need for ice and makes it ideal for serious cold therapy. It is also perfect for patios or backyard installations thanks to its durable and weather-resistant build. 

However, its size and weight make it less practical for indoor use or smaller spaces.

Ideal for: Outdoor enthusiasts wanting a high-capacity, heavy-duty tub.
