Everestplunge Reviews 

We are extremely disappointed with our experience dealing with Everestplunge.
We paid our deposit in March and were advised that delivery would take 4–6 weeks. Unfortunately, that timeline came and went with little to no communication. Throughout the process, we repeatedly had to chase updates ourselves, as emails and enquiries often went unanswered. When we finally received information, we were told there would be further delays, but again there was very little proactive communication from the company.
After months of waiting, we travelled from Whangārei to Auckland to collect our sauna, only to discover it was not the black model we had ordered. To make matters worse, the packaging was labelled with someone else's name, leaving us questioning whether we had even been given the correct product.
Once we started assembling the sauna, we found there were no instructions included, making the setup far more difficult than it should have been. The air purifier supplied also appeared extremely outdated and was broken on arrival.
Everestplunge has offered to have the sauna painted black, (which I highly doubt they will front up to doing because they are so useless in even picking up the phone) despite raising these concerns in writing via, we have yet to receive a response.
I get delays can happen, but poor communication, incorrect products, missing instructions, faulty components, and the lack of follow up have made this a very frustrating and disappointing experience. Based on our experience, we would NOT recommend Everestplunge to anyone.

Extremely Disappointing Experience – Poor Product Design, Dismissive Customer Service

I purchased a cold plunge and sauna from Everest Plunge, spending thousands on the setup including $700 for installation. At first, I was genuinely happy with the product and expressed that — but unfortunately, that quickly changed.

Within just two months, the chiller motor failed, despite me following the setup instructions exactly as given. The plunge was filled with water, water was circulating through both pipes, and the unit was functioning when I walked away. The damage happened overnight, due to a system that lacks basic protective features like an auto shut-off or alert when water stops circulating — a serious design flaw.

When I raised this, I was blamed for the failure, offered a “discounted repair” of over $550 + GST, and pressured with a time limit. No shared accountability. No genuine interest in resolving the issue. Just defensiveness, threats of legal action, and complete dismissal of my experience.

This wasn’t the first red flag. Weeks earlier, the sauna door dropped due to poor installation and started scraping the base. When I asked for help, I was told to fix it myself — despite paying a premium for professional installation.

This has been stressful, time-wasting, and incredibly disappointing. I’ve since learned other customers have experienced similar issues, and I’ll be pursuing this through Consumer NZ and the Disputes Tribunal.

I would not recommend Everest Plunge to anyone unless you are prepared to be blamed and ignored if something goes wrong.

A good product should be backed by good people — this one isn’t.
