How do I maintain my cold plunge tub?

Maintenance is simple and keeps your water crystal clear for months: Replace the 20-micron filter every 2-4 weeks (based on usage). Sanitize the water weekly using a non-chlorine-based treatment. Clean the strainer weekly to prevent debris buildup. We’ve tested it for 6+ months without a water change when properly maintained.

Do I need to change the water?

Not often! Thanks to advanced filtration and sanitation, you can go months without changing the water. Light use (<4 week): Replace water every 4-6 months. Heavy use (7/week or multiple people daily): Every 1-2 months. Just replace the filter monthly and add sanitation weekly—your water stays pristine.

Can I use the cold plunge outdoors?

Yes! The Inergize Cold Plunge Tub is IPX4-rated, meaning it's splash-resistant and safe for outdoor use. Best setup: Place in shade or shelter for better efficiency and longer lifespan. Cold climates: If temperatures drop below 33°F, drain and store to prevent freezing damage.
