WHAT CERTIFIED REFURBISHED MEANS

Every Certified Refurbished unit is inspected, repaired and tested at our facility in San Diego before it ships. Units may show cosmetic marks such as scratches, small dents or minor chips. Those marks do not affect performance or function.

COLD THERAPY

Powerful Benefits of Cold Therapy

A daily plunge isn't a hack. It's a practice that compounds across your body and mind.

Sharper focus

Cold triggers a sustained dopamine and norepinephrine release. Most owners report two to four hours of clear, calm focus.

Stronger resilience

Three minutes of cold trains your nervous system. The carryover shows up in every hard thing you do.

Faster recovery

Cold reduces inflammation and post-training soreness. Athletes have used it for decades. The research caught up.

Deeper sleep

A morning plunge reinforces your circadian rhythm. Most owners report deeper sleep within the first month.

Elevated mood

Cold immersion drives a measurable lift in dopamine. Owners describe a steady, sustained sense of calm energy.

Reduced inflammation

Cold immersion lowers systemic inflammation. The same mechanism athletes have relied on for serious recovery.

Better metabolism

Cold activates brown adipose tissue and supports metabolic health. Real, modest, well-documented in the research.

Stronger immunity

Regular cold exposure is linked to increased white blood cell activity and fewer sick days reported by owners.

CERTIFIED QUALITY

FAQs

When will it ship?

If in stock, ships next business day. Current lead time below the Add to Cart button. Free shipping to lower 48.

Will I fit? I'm tall.

Yes. 30" deep and fits users up to 6'5" / 300 lbs. Verified owners over 6'4" report full neck-deep submersion without yoga poses. Internal dimensions: 45" long × 21.5" wide × 30" deep.

Can I put it outside? Is it weather-proof?

Yes. The Elite is rated for both indoor and outdoor use. UV-stable PVC outer shell, IPX-rated chiller, insulated code-lock lid keeps debris out. Use year-round in non-freezing climates. In freezing weather, bring it inside or empty it. The chiller works harder in extreme heat but performs reliably.

Is it actually portable?

Yes. The tub itself rolls up and packs into the included travel backpack, weighs ~40 lbs deflated. The chiller is on caster wheels and connects via flexible hoses. Many owners move the whole setup between garage, patio, and indoor space seasonally. Several owners take it in their RV.

How well insulated is it? Will it run up my electric bill? Does it run 24/7?

It's built to hold temperature. 4" of total wall air insulation and 4" insulated lid locks in cold when you're not using it.

The chiller can run 24/7 but most people don't. Most owners schedule it around their routine through the app.

Example daily routine:

4:00 AM: chiller switches on automatically (1 or 2 hours before plunge)

5:00 AM: water at 37°F, you plunge

5:30 AM: chiller runs another 30 minutes to filter and clean

6:00 AM: chiller off until your next session

Real-world energy cost at $0.15/kWh:

Typical owner (3 hours/day scheduled): ~$12/month

Light use (1.5 hours/day): ~$6/month

Maximum (24/7 continuous, rare): ~$96/month

The 4-inch insulated walls and 4-inch lid hold cold for hours between sessions, so the compressor only kicks back on briefly when water rises a few degrees above target. Schedule through the Tuya app or onboard touchscreen.

Does it need a special outlet?

No. Standard 120V / 15A grounded outlet. Dedicated circuit recommended for best performance.

What is the warranty?

Certified refurbished units have a 90 day warranty.

    Essential Part of My Wellness Routines!

    I’ve had the for over a year now and love it! The quality of the tub and chiller are excellent. Customer service is very responsive and thorough. I’ve no doubt I chose the right company and equipment for my cold plunge experience. My go to is contrast therapy between this and my sauna at least 4 times a week.

    Great Customer Service

    I had the ozone generator part go bad on my unit but the support team responded to my issues rapidly and remained in good communication through out the repair. They allowed me to make the repair on my own which was great as it saved on the shipping from Hawaii back to Inergize HQ.

    While I made the repair I could attest to the claim of exceptional build quality as every part seemed robust and well arranged. I was impressed with the overall quality the internal parts. I did make one suggestion to the hose line on the ozone generator. The repair was easy and works great again.

    I love using it again almost every day as part of my routine! I highly recommend going with Inergize for your cold plunge purchase.. 🤙
