1. Stable Construction
The Indoor Cold Plunge Tub features a composite structure with a 0.3mm eco-friendly PVC outer layer, a 2mm pearl cotton insulation layer, and a 0.35mm nylon fabric. The overall pressure test shows it can withstand a static load of ≥120kg. Multiple support feet at the bottom distribute the weight, increasing single-point load-bearing capacity by approximately 30%, maintaining vertical stability even when full of water, preventing tilting or deformation, and making it suitable for frequent use.
2. Excellent Insulation
The multi-layer composite structure controls the water temperature drop rate to ≤2℃ per hour in a normal indoor environment. In 15℃ cold water conditions, using the lid allows for approximately 60 minutes of effective cold water immersion, reducing the need for frequent water changes, improving single-use efficiency, and meeting standard cryotherapy duration requirements.
3. Portable Design
The tub can be completely folded, with a folded thickness of approximately 15% of its original height. The 85cm size folds down to a height of ≤15cm. A single person can unfold or fold it in 30 seconds, and the overall weight is within a portable range, making it easy to move between different rooms or store.
4. Sealed Design
The Indoor Cold Plunge Tub uses an integrated heat-sealing process for its joints, with a welding width of ≥8mm, and has passed a 48-hour static water test without leakage. The drain outlet is located ≤2cm from the bottom, reducing residual water to less than 3% of the tub's volume, minimizing water accumulation, odors, and cleaning burden.
5. Safe Materials
The rounded, thickened air ring has a thickness of ≥5cm, providing more even pressure distribution at the edges and reducing pressure on limbs. The inner wall's friction coefficient is tested to be approximately 20% higher than ordinary PVC surfaces, improving sitting stability in wet environments, suitable for the high-frequency cold water use of the Indoor Cold Plunge Tub.
1. Home Bathroom
Suitable for use in typical residential bathrooms, the Indoor Cold Plunge Tub can replace fixed cold bath equipment. The 85cm diameter size can be placed independently within a standard shower area, with a water volume of 150–180L, meeting daily cold water immersion needs without affecting the use of other bathroom facilities.
2. Fitness and Recovery Area
Suitable for home gyms or private training spaces. Cold water immersion temperature is typically controlled at 10–15℃, with 10–15 minutes of use per session, aiding in post-exercise recovery management. The foldable structure allows for convenient storage during non-training periods, improving space utilization.
3. Physiotherapy Studio
Suitable for use as auxiliary equipment in small physiotherapy or rehabilitation studios. Compared to rigid bathtubs, this product requires no fixed installation, offering greater flexibility in drainage and movement, reducing renovation costs and making it suitable for phased deployment in multi-functional therapy spaces.
4. Guesthouses and Vacation Rentals
Used as a featured amenity in high-end guesthouses or short-term rental spaces. The Indoor Cold Plunge Tub can be flexibly placed or removed depending on the occupancy period, avoiding long-term space occupation. When folded, it can be stored centrally, making the configuration and management costs for individual rooms more controllable.
5. Temporary Recovery Space
The Indoor Cold Plunge Tub is suitable for temporary indoor recovery areas at events, training camps, etc. It requires no complex installation; simply fill with water for use, meeting the needs of concentrated recovery during specific periods. After use, it can be quickly disassembled and transported, without affecting the subsequent use of the venue.
A: The overall height of the product is approximately 75–85cm. In a seated position, the water level can cover the area from the waist to below the chest. It is suitable for people with a height of 160–190cm, allowing for standard cold water immersion in a seated or slightly bent position.
A: The tub itself does not have a cooling function; the water temperature depends on the water source. With the addition of ice, the temperature can be stably maintained in the 5–10℃ range. The insulated structure can maintain an effective cold therapy temperature range for 60 minutes.
A: Using heat-sealed welding and thickened composite materials, it is not prone to leaks or bulging under normal use conditions. It is recommended that the water level does not exceed the marked line on the inner wall of the tub to ensure balanced structural stress.
A: The inner wall is a smooth PVC layer; simply rinse with clean water after draining. It is recommended to perform a thorough cleaning every 3–5 uses. After drying, fold and store it to effectively prevent odor retention.
A: The material has been tested for over 500 folding cycles, demonstrating good durability for daily home or recovery use. Reasonable control of water volume and folding methods can extend the overall service life.
