FAQ
How does cold water therapy work?
Cold water therapy, also known as cold plunging or cold immersion, involves immersing the body in cold water for a short period of time. This process can help reduce inflammation, improve circulation, and promote overall wellness.
What are the benefits of using a cold tub?
Regular use of a cold tub can help reduce muscle soreness, speed up recovery after workouts, boost circulation, reduce inflammation, and improve overall mental clarity and focus.
Are cold tubs safe for everyone?
Cold tubs can provide numerous benefits, but they are not necessarily safe for everyone. People with certain medical conditions, such as heart issues, high blood pressure, or circulation problems, should consult with a healthcare professional before using a cold tub. The sudden drop in temperature can stress the cardiovascular system, which might be dangerous for individuals with underlying health concerns.
Pregnant women, individuals with diabetes, or those who have recently undergone surgery should also get medical clearance before using cold therapy. In general, it's always a good idea to ease into cold tub use, starting with shorter sessions at moderate temperatures, and pay attention to your body's response.
How long should I stay in the cold tub?
It's recommended to start with shorter sessions, around 3–5 minutes, and gradually work your way up to 10–15 minutes, depending on your tolerance and comfort level. If you feel your body start to shiver, you must exit the water immediately!
What is the ideal water temperature for cold water therapy?
The ideal temperature range for cold water therapy is typically between 36°F and 59°F. This range provides the most benefits while still being manageable for most users. The goal is to get your body to a shiver state within the desired timeframe, so adjust your temperature accordingly!
How often should I use the cold tub?
Frequency can vary based on your goals and recovery needs, but many people use their cold tubs 3–5 times per week. For athletes or individuals looking for faster recovery, daily use is also common—or even multiple times a day!
What sets ReGen Cold Tubs apart from other cold tubs on the market?
ReGen Cold Tubs are built with quality and durability top of mind. Our tubs are constructed with professional-grade components and undergo rigorous testing to ensure they meet the highest standards of excellence!
All ReGen tubs are built with a High Flow Rate and Oversized Components. Our tubs are built with the same components and plumbing that most underground pools are built with.
High Flow Rate helps provide a better user experience, as it breaks through your body's thermal barrier so you feel the true temperature of the water the entire time you are in the tub! This high flow rate also provides cleaner and clearer water, as our water is going through micron filtration every 3–5 minutes!
What temperature range does a ReGen get to?
Our Heavy Duty chiller lineup can be adjusted between 36°F and 82°F, giving you complete control over your cold plunging experience. Please note, our chillers will not heat the water.
How big is a ReGen tub?
The size and dimensions of our ReGen tubs depend on the model. We include full specifications on each model’s product page, including size and dimensions.
What does the maintenance typically consist of?
Any cold tub on the market requires ongoing maintenance. We’ve designed the ReGen tubs to be as easy to maintain as possible. On average, you should expect to spend about 10 minutes/month to maintain your tub.
Maintenance typically consists of:
-
Filter Maintenance: Micron filtration down to 20 microns. Filters need replacement every 4–8 weeks depending on model.
-
Balancing the Water: Maintain pH and chlorine levels. A professional test is recommended.
-
Chiller Maintenance: Clean screens and vents monthly.
-
Water Changes: Most residential customers change water every 6 months, depending on use.
What is the electrical requirement?
All of our tubs plug into a 120V GFCI outlet. The amount of amperage depends on the model you choose. Please review each product page for the exact specs.
Can I place a ReGen tub inside or outdoors?
Yes, ReGen tubs can be placed indoors or outdoors. If outdoors, place it somewhere not subject to flooding. Indoor placements may require professional movers due to the tub's weight, especially for upper floors or basements.
How easy is it to change the water? How often should I drain the tub?
All tubs include a plumbed hose bib for easy draining. In residential settings, we recommend draining the tub every 6 months. In commercial or high-use settings, more frequent changes may be needed. Always rinse off before entering to help maintain clean water.
How energy efficient is a ReGen tub? What’s the cost to run this?
ReGen tubs are built to be extremely efficient using high-quality insulation and a well-insulated cover. On average, expect energy costs to be around $0.60–$0.80 per day depending on usage.
Is there anything else I need if I purchase a ReGen tub?
No, ReGen tubs come with everything needed to operate your cold tub and keep it clean. We also include a Product Recommendation document with optional accessories for those who want more.
How does a ReGen tub perform in hot or cold climates?
ReGen tubs are designed in Arizona and can handle extreme heat and cold. High Flow Rate + quality insulation ensures performance in 115°F summers or freezing winters. We offer Help Center tips for protecting performance in extreme climates.
How easy is setup?
ReGen tubs can be setup in minutes. No tools or professionals are needed.
What is the warranty coverage for ReGen Cold Tubs?
