On-Site Highlights

At this exhibition, Alphasauna attracted a large number of visitors with its innovative cold plunge tub design. Our booth fully displayed our products and set up an experience area where customers could personally experience the efficient cooling function of the new cold plunge tub and feel its unique design. Upon learning of our participation, our loyal customers responded enthusiastically, expressing strong interest in the cold plunge tubs and actively inquiring about product details.
As a brand-new product of Alphasauna, the debut of this cold plunge tub has attracted widespread attention. We also demonstrated on-site how the cold plunge tub can control the temperature through a smart WiFi chiller and manage settings through an app, giving customers a more convenient user experience.

Alphasauna’s Unique Design Concept

This cold plunge tub has a novel design. Our Alphasauna is inspired by the design concept of diving and plunging, and has achieved breakthrough innovations in appearance design and performance.
The stepped handrail of the cold plunge tub is designed with reference to the swimming pool handrail and is combined with the deep structure design of the tub. It fully considers the principles of ergonomics and sets a seat in the tub to meet the customer’s needs for full-body immersion and provide a more comfortable user experience.
Our designs are currently patented, and both styles and performance are produced exclusively by us, ensuring quality and differentiated competitive advantages.

Exterior Design

The overall black design exudes a modern, minimalist feel. This design can be integrated into a variety of indoor or outdoor spaces, whether it is a high-end spa, gym, or outdoor garden, it can be well-decorated and adopted. It can also be paired with our black spray-painted sauna room to combine hot and cold therapy for a dual experience.

Smooth Shape and High-End Texture

The curved tub rim and square stepped surface create a sleek, simple design that exudes a sense of luxury. Paired with metallic components, it blends exquisite textures with an industrial style, creating a visually appealing experience.

Wifi Intelligent Temperature Control System

This unique cold plunge tub also features a luxurious WiFi chiller and an external LCD touch panel for intuitive and convenient operation. It also supports independent app control, enabling easy, intelligent operation and personalized adjustment.

Flexible Bottom Movement Design

The cold plunge tub is equipped with a sliding track at the bottom and wheels for easy movement, making it more flexible to use and very practical and convenient.

High-Quality Material Structure

At Alphasauna, we believe the quality of a cold plunge tub lies not only in its cooling performance but also in its structural design and material craftsmanship. To ensure a more stable and reliable ice bath experience for outdoor use, our new cold plunge tub design seamlessly integrates weather resistance, comfort, and aesthetics, meticulously crafting every detail from the materials used to the construction.

Metal Finish Combined with Stainless Steel Lining

The cold plunge tub features an integrated tub and chiller design. Its exterior is finished with a galvanized paint finish and a 304 stainless steel lining, offering exceptional durability and a premium feel while also meeting environmental standards. Furthermore, the high-temperature outdoor coating effectively resists UV rays and rain, extending the cold plunge tub’s lifespan and making cleaning and maintenance easier and more convenient.

Small Footprint, Customizable Colors

The tub measures 1400mm in length, 778mm in width, and 1260mm in height, occupying a compact footprint. Despite its compact size, the interior is thoughtfully designed to ensure a comfortable soaking experience while maintaining efficient cooling. The exterior paint color can be customized, with a wide variety of colors and finishes available, from subdued black and gray or vibrant metallics, creating a unique visual impact for your space.

Integrated Refrigeration System and Convenient Maintenance

A built-in chiller is located beneath the steps, forming an integrated structure with the tub for enhanced overall comfort. The chiller also features a built-in ozone generator and filter. Replacing the filter is simple: simply open the metal ventilation grille, remove the old filter, and replace it with a new one. Both sides can be opened for added convenience.

Efficient Heat Dissipation

There are ventilation nets on both sides of the steps and at the bottom of the front, equipped with cooling fans. There is a protective cover on the top of the cold plunge tub to facilitate timely heat dissipation when the chiller is running, thereby speeding up the cooling speed of the cold plunge tub.

Hidden Storage Space

The bottom step is designed as a storage box, which allows customers to store personal items such as towels and clothes. It not only saves space but also improves convenience.

Comprehensive Intelligent Dual Temperature System

This refrigeration unit supports bidirectional cooling and heating functions, flexibly adjusting the water temperature between 3°C and 40°C to meet the needs of various environments. Its exceptional cooling efficiency can reduce the water temperature by an average of 4–5°C per hour. Its robust power output of up to 1.3HP provides stable and efficient performance support for the temperature control system. Its multi-layer, high-efficiency insulation structure effectively minimizes temperature loss, improving energy efficiency and making the entire cooling and heating process more energy-efficient, rapid, and stable.

Market Environmental Certification

This cold plunge tub has passed numerous international safety and compliance certifications, including CE, ETL, PSE, and SAA, fully meeting the safety and performance standards of various countries and regions. Each cold plunge tub undergoes rigorous testing before shipment to ensure stability and reliability, ensuring true quality control and traceability. With the assurance of these certifications, you can be confident in your use, whether for personal use or commercial projects.
