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.

We’ve fit a 250lb+ person before, you just need to be careful of the water level check out some photos here.

We’ve also had multiple >6ft 5” users comfortably fit and head dunk without their knees popping out or water spilling over the edge.

"Best part is that being 6’- 4” I STILL totally fit in the tub, all the way submerged up to my chin, without needing to do a yoga pose just to fit. I can comfortably sit, fully under the water, every time AND I can grab the top rails to pull myself up when getting out (unlike a normal tub)." - Ian Rice.

The Inergize Chiller connects to the Tuya Smart App via WiFi, allowing you to:

• Control temperatures remotely (adjust between 37°F and 105°F with the Pro model).
• Preprogram on/off schedules to save energy and ensure your plunge is ready when you are.
• Set different temperature schedules for morning and evening plunges.

No manual adjustments needed—control everything from your phone.

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.

It cools about 6-7F per hour when ambient is at 65F. It will take about 4-5hrs to get cold enough to plunge.

The pro has a 0.8HP chiller so works great in hot climates, if in temperatures >100F the water temperature might tick up slightly.

• Whisper-quiet when maintaining temperature.
• During active cooling/heating: Runs at ~60 decibels (about as loud as a quiet conversation or small portable AC unit).
