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.

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.

No. The Eco runs on a standard 110–120V line at 4.5A, so there’s no need for a dedicated circuit or breaker upgrade.

Absolutely! The Inergize Cold Plunge Tub is made from military-grade drop-stitch polyester fabric, the same rigid, high-strength material used in inflatable paddle boards and kayaks.

• Supports 200 lbs on the edge without bending or spilling.
• As strong as an acrylic bathtub, yet portable enough to roll into a duffle bag.

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.

Both deliver industry-leading performance, but here’s how they compare.

Under typical 60°F ambient conditions, our system cools water at 2.7°F per hour, reaching your ideal plunge temperature in about 8 hours—and then maintains that temperature 24/7, so it’s always ready when you are.

The Eco has a 0.25HP chiller so the temperature might not get all the way down to 38°F in extreme heat.

Whisper-quiet when maintaining temperature. Runs at ~50 decibels when cooling, comparable to a quiet conversation at home.
