It weighs about 238 pounds when empty and around 1,150 pounds when filled with its 105-gallon capacity. The system could cool water by 10–12°F per hour and heat at 4–5°F per hour (if the optional heater is used). A 1 HP chiller may maintain the 37°F temperature in environments as warm as 120°F, operating on a standard 15-amp circuit.

   The makers state that using the All-In for cold plunging regularly could support muscle recovery by improving blood flow and might help boost immune function by increasing white blood cell production. It might also help influence mood by raising norepinephrine and dopamine levels, which may act as natural mood stabilizers.

The shell is made from high-grade polyethylene, which could resist UV exposure and help maintain water temperature through built-in insulation. The Pod might work well for patios, balconies, or home gyms where space is limited. The makers highlight that it could accommodate users up to 6’7″ and may be quick to set up. It measures 45″ long, 30″ wide, and 34″ high. When empty, it weighs around 94 pounds and approximately 820 pounds when filled with its 87-gallon capacity.

Several accessories are included with The Plunge Air, such as an insulated clip-on inflatable lid to retain cold and block debris, a matching ground cover for added protection, a repair kit for minor issues, and a backpack that could make transport easier.

5. Plunge Pop-Up

   The Plunge Pop-Up might be suitable for you if you are  6’9″ (206 cm) and could hold a large amount of water relative to its compact form. You might use it as a DIY ice plunge or connect it to a compatible Evolve Chiller for a more controlled temperature experience. The materials used in its construction could help maintain cold temperatures while keeping setup and maintenance relatively easy. As per the official website, the Plunge Pop-Up comes with an elastic Pop-Up cover to keep out debris (an insulated lid is sold separately), a manual air pump for inflating the top ring, and manifold plugs to seal the tub when not connected to a chiller.

   To support year-round use, the system includes optional seasonal protection that helps prevent freezing in colder months. The Party Plunge includes accessories like a clip-on inflatable cover, a ground cover for additional surface protection, a repair kit for small issues, and a standing pump to assist with setup.

8. Evolve Chillers

Plunge Advantages

1. Focused On Smart Technology

   Plunge integrates smart technology into its product lineup to help you build lasting cold or heat therapy routines. Through its mobile app, compatible with both iOS and Android, you can remotely control water or sauna temperatures between 39°F and 103°F, power devices on or off, and schedule sessions in advance. This applies across models like the Plunge All-In and Plunge Sauna, offering control flexibility whether you’re at home or away. The app also tracks important session data, including plunge duration, usage frequency, and water temperature, providing insight into your habits over time. For units equipped with the Evolve chiller, you’ll receive automated maintenance alerts, such as filter-change reminders, to help avoid performance dips. Session streaks, usage charts, and guided onboarding steps are designed to reinforce adherence and remove guesswork, especially helpful if you’re just starting or trying to build long-term consistency. This level of app-based support reflects Plunge’s focus on reducing daily friction and making recovery routines measurable, repeatable, and easier to maintain. This means less manual oversight and more time focused on your wellness goals.

2. Offers a wide product range

   Plunge offers a range of options in cold and heat therapy products designed to suit different spaces, budgets, and usage needs. For cold therapy, the brand options include the Plunge All‑In, the Plunge (Tub Only), and the Plunge Pod. As per the official website, Plunge also provides portable models such as Plunge Air (inflatable) and Plunge Pop-Up (foldable), which are compact, easy to set up, and suitable for travel or smaller spaces. You can also combine hot and cold therapy through bundles like the Plunge All-In + Sauna, which supports contrast therapy. This range allows you to choose a setup that fits your space, lifestyle, and goals, whether you’re starting small, building a full home recovery zone, or looking for portable options.

Plunge Limitations

1. Limited Technical Support Availability

   Plunge’s limited technical support is a recurring concern among Reddit users and online reviewers, especially if you are living outside major cities. Many customers report delayed technician visits, lack of product-specific expertise, and the absence of direct phone support for troubleshooting. These reviews suggest that if you experience a mechanical issue or a chiller failure, you may have to wait days or even weeks for resolution. Some users have even had to diagnose and fix problems themselves due to unavailable or undertrained technicians.

   This gap in support can seriously disrupt your experience, especially if you’re relying on your plunge or sauna as part of a wellness routine or operating a commercial setup. Without fast repairs or easy access to replacement parts, you risk extended downtime, frustration, and diminished confidence in the brand’s reliability.

Plunge Alternative Brands

1. Ice Barrel

   Plunge and Ice Barrel take fundamentally different approaches to cold therapy, addressing distinct user preferences and lifestyles.

   Ice Barrel emphasizes a raw, minimalist experience. Its signature upright, barrel-style tubs are designed for seated immersion and are available in models like the 300, 400, and 500, each varying in size, insulation, and chiller compatibility.

   Constructed from durable, BPA-free plastic, Ice Barrel units are lightweight, portable, and made in the USA. They don’t include built-in chillers. Instead, you manually add ice to cool the water. However, the 300 and 500 models by Ice Barrel can connect to an external chiller if desired.

   On the other hand, Plunge positions itself as a high-end, tech-forward wellness option by offering Cold Plunges ranging from $2000 to $9000. Its cold plunge systems feature fully integrated chillers capable of maintaining water at a consistent 37°F without the need for manual ice. The tubs, crafted from high-gloss acrylic and fiberglass, are ergonomically designed for full-body, reclined immersion, even accommodating users up to 6’9”. The official website highlights that Plunge also offers Saunas for hot baths, which is missing in  Ice Barrel’s offerings.

   Plunge models include advanced features like ozone sanitation, 20-micron filtration, LED lighting, and smartphone connectivity through the Plunge app. This enables precise control over temperature, session timing, and maintenance, offering a seamless and hygienic cold therapy routine. Plunge’s plug-and-play setup supports both indoor and outdoor use.

   Ice Barrel focuses on cold therapy, and if you are looking for an unplugged, self-directed experience, on the other hand, Plunge offers integrated, tech-heavy, and automated features.

2. The Cold Pod

   The Cold Pod and Plunge both offer cold therapy options, but they could suit different user needs, with significant differences in design, functionality, and user experience.

   As per its official website, the Cold Pod offers an upright, barrel-style tub, featuring an inflatable top ring, removable legs, and a compact footprint. However, it lacks an integrated chiller or filtration system, meaning you must manually add ice to achieve cold temperatures. This makes temperature control highly dependent on ice availability and ambient conditions, which can lead to inconsistent cold exposure.

   The Cold Pod’s offerings are available in two sizes (Standard: 320 L; XL: 440 L), and though it includes insulation, it’s mainly designed for short-term, low-tech use. The brand’s tub requires manual maintenance as you are responsible for regular draining, refilling, and cleaning to maintain hygiene.

   On the other hand, Plunge offers a far more advanced and automated experience. Its range includes models like the All-In, Plunge, Pod, and Air, all of which come with integrated chillers that maintain water temperatures as low as 37°F without the need for ice. Many brands’ models feature ergonomic, spacious tubs that support full-body immersion, even for users up to 6’9”.

   Cold Pod positions itself as a highly affordable, beginner-friendly option in the cold immersion market. Their products are typically priced under $500, with the Cold Pod XL (440L) currently available at a discounted price of $182 (regularly $245) and the Elite Lite Barrel (450L) priced at $447 (down from $697). These models emphasize portability, easy setup, and accessibility if you are looking to try cold therapy without investing in large, permanent installations.

   On the other hand, Plunge is aimed at a more premium audience, offering advanced cold plunges with integrated chillers and smart features. Their pricing starts at $2,990 for the Air model (inflatable) and goes up to $8,990 for the All-In system, originally priced at $9,990. The lineup includes various models like the Plunge Pod at $4,490, the Plunge at $5,990, and premium sauna bundles ranging up to $20,980. These price points reflect higher-grade construction, integrated cooling systems, and app-based control features.

   Cold Pod offers a straightforward 14-day return window, and there’s no stated restocking fee or explicit detail about who covers return shipping, making it appear relatively user-friendly for domestic buyers. The brand also provides a 1-year warranty covering manufacturing defects, as long as you register the product. However, accidental damage, misuse, and aesthetic wear and tear are not covered.

   Plunge offers a more detailed and structured return policy, giving users up to 30 days to return their cold plunge or sauna units. However, this comes with a 15% restocking fee, and customers are responsible for return shipping costs. Refunds are processed only after the product is inspected, with a waiting period of 7–10 business days after the item is received. Plunge does offer a 30-day trial on the Air model, which allows for a full refund if the product doesn’t meet expectations, provided it’s unused. Warranty coverage includes 12 months for plunge tubs and 24 months for saunas, with options for extended protection.

   Cold Pod comes with a low price point and basic warranty support. On the other hand, Plunge offers high-end, fully featured systems with extended functionality, but you’ll pay more upfront and face stricter return conditions.

How Did We Evaluate Plunge?

1. Brand Credibility

   We looked at a combination of brand age, background, and consumer trust indicators like Trustpilot and BBB ratings to analyze Plunge’s reputation. Founded in 2020, Plunge entered the wellness space as a cold therapy brand offering sleek, tech-enabled products. The brand is known for its modern design, integrated chillers, and app connectivity. However, as a relatively young company, it is still in the process of establishing long-term credibility and consistency.

   We also considered how customers perceive Plunge through third-party review platforms. On Trustpilot, the brand has a 3.5-star rating based on over 100 reviews. Feedback is mixed as some users praise the product’s performance and aesthetic, while others report issues like shipping delays, technical malfunctions, and lackluster customer service.

   Another concern is Plunge’s F rating from the Better Business Bureau (BBB). This rating often reflects unresolved complaints or poor communication from the company, which suggests deeper issues with accountability. While the product itself may meet expectations for some, the overall ownership experience could be frustrating if problems arise and support is not responsive.

2. Consumer Feedback

   To evaluate Plunge, we examined a wide range of Trustpilot reviews from actual customers, covering both personal and commercial use cases.

   Many customers report meaningful health benefits from using Plunge products, especially for joint pain, inflammation, and recovery. Several users, ranging from older adults to athletes, shared positive experiences with the cold tubs, highlighting improvements in sleep quality and circulation. These reviews also noted that the design is sleek, the setup process is straightforward, and customer service was responsive when things went smoothly.

   At the same time, a significant number of users raised concerns about product reliability and ongoing maintenance issues. Common complaints include chiller malfunctions, pump failures, and electrical faults, often within the first year of use. For some, these problems led to repeated service requests and extended downtime. Commercial users in particular emphasized that the equipment didn’t hold up under regular business operations, despite being marketed for that purpose.

   Customer support experiences varied widely. Some reviewers felt well-supported, while others described delays in communication, inconsistent troubleshooting, and limited help during warranty claims. There were also cases where replacement parts arrived damaged or didn’t resolve the issue, causing further frustration. Although Plunge does respond to complaints and occasionally makes exceptions to its policies, several customers felt the resolution process required more effort than expected for a high-end product.

   While Plunge claims to provide value for wellness-focused users, those considering a purchase, especially for commercial use, should be aware of the possible service and durability challenges reported by others.

Frequently Asked Questions

1. Does Plunge require professional installation, or can I set it up myself?
   Mostly. Plunge setup is manageable without professional help, but it can still take a few hours due to the unit’s size and weight. You’ll require access to a standard electrical outlet and a level surface. Having an extra person during setup can make the process smoother.
2. Can the Plunge offerings be used outdoors year-round?
   Yes, but you’ll need to account for weather extremes. In colder climates, you may experience issues with freezing components. It’s best to place it in a covered or semi-enclosed area and winterize if temperatures drop below freezing.
3. Can I use Epsom salts or other additives in the Plunge’s cold tub?
   It’s generally not safe. Salts and other substances can damage the filtration system or chiller components offered by Plunge. If you want therapeutic benefits, you’ll need to keep them separate from your cold therapy routine.

Conclusion

Plunge offers a range of cold therapy and contrast therapy products that may support recovery and stress reduction. With U.S.-based assembly and a focus on engineering, the brand emphasizes precision temperature control, smart app connectivity, filtration systems, and product variety to meet different user needs.

Research supports the use of cold water immersion for reducing inflammation, aiding muscle recovery, and improving mood regulation when practiced appropriately. Plunge integrates this approach into a structured platform, allowing for scheduled sessions, progress tracking, and remote management through its dedicated app.

However, the brand has limitations. Customer feedback points to issues with delayed technical support, challenges with warranty claims, and inconsistent service quality. The brand’s lower BBB rating and some negative third-party reviews suggest that post-purchase support may not always meet expectations. Pricing may also be a barrier, especially if you are seeking more affordable recovery options.

While cold therapy has documented benefits, it’s not suitable for everyone. People with cardiovascular conditions, high blood pressure, or other concerns should consult their doctor before use. It’s also important to follow recommended session times by Plunge and temperature guidelines to avoid adverse effects.
