In most households more than one person uses the product. It costs enough! Make the experience user friendly for all those that plunge! Every update takes my app/plunge connection offline and it is murder trying to re connect. Super inconvenient ### 2/5 — This sauna is trash *2026-03-30, version 4.4* I am unable to get my sauna above 150°. The floor of my sauna won’t get above 90°. However, the sensor tells me it is 215° in the sauna. The craftsmanship and technology do not work. Do not buy this sauna. I repeat. Do not buy this sauna. You will not be able to get the health benefits you want because it does not heat up enough even though it tells you it does. Why not give it one star? That’s simply because I like my cold plunge. The cold plunge works well. ### 2/5 — Can’t see water flow *2026-03-24, version 4.4* In the app on my phone, I can’t see all the words in the water flow section. ### 3/5 — Get with the times *2026-03-18, version 4.4* Should allow more than one person to use the app without someone having to sign out and sign back in EVERY time. In most households more than one person uses the product. It costs enough! Make the experience user friendly for all those that plunge! ### 4/5 — Good, BUT… *2026-03-10, version 4.3* Love it. Simple to use, good graphics, BUT why isn’t there a steam room timer??? ### 2/5 — Weak app *2026-03-07, version 4.3* Plunge app never stays connected, adding it over and over just gives u multiple tubs. The cold plunge is awesome. ### 1/5 — horrible app *2026-03-02, version 4.3* it logs you out regularly and then you have to manually type in your email and password cu it is not integrated with Passwords on iOS. horrible and stupid ### 1/5 — Garbage *2026-02-27, version 4.3* The Plunge needs major repairs every 3-4 months. Buy a chilligoat instead. ### 1/5 — Terrible app and support *2026-02-22, version 4.3* The app is so unstable and terrible and buggy it’s almost unusable. I’ve run into a number of basic issues with logins, logouts, connection to the sauna, vague error messages, etc. Please have your developers use Claude Code to build the most basic test harness and functionality, this is beyond embarrassing. I can’t recommend the product like this. ### 1/5 — Second plunge *2026-02-18, version 4.1.1* I had one of the original plunges in my house in California and since moved to Az. I purchased a much more expensive version called all in one and it has been a nightmare. After 2 months of dealing with filter problems and 2 leaks I finally got it working. Customer service was a joke and getting someone to come out and fix it 2 times took forever. For 9,000 dollars you would think it would work but when it doesn’t you would think it would be dealt with in a timely manner. You can’t talk to anyone on the phone and emails are not answered for days. Takes weeks to get them to send a tech out to fix it. Worse experience for 9,000. ### 1/5 — Support Non-Existent *2026-02-07, version 4.1.1* I have had my sauna for a little over a year and it warped and will not hold heat. I have reached out to support over a handful of times without success. They respond immediately, likely AI, and then ghosts you. Whatever system they are using will not respond back after the initial. I would stay away given their very poor customer service. ## Most critical reviews (10 lowest-rated) ### 1/5 — The “All-In One” cold plunge is a Lemon *2026-09-01, version 4.7* Purchased 18 months ago. Constant mechanical issues with my All-In one. Zero customer support (impossible to reach a human at company to discuss). Terrible customer support and a lemon product ### 1/5 — Abysmal quality *2026-08-28, version 4.7* Do not buy Plunge. I own the Plunge Pod with the Evolve Pro Chiller, and it’s had two critical failures: the chiller previously went into an error state for no reason and needed a full replacement, and now the clear filter housing canister has cracked on its own — a manufacturing defect that risks leaking the entire tub since it sits right in the water line. Plunge doesn’t even sell this part directly on their site, and instead of standing behind their own product, customer service pushes you toward a third-party insurance claim (Plunge Protect/XCover) rather than just fixing a known defect. You will spend far more time fighting through claims and troubleshooting than you’ll ever spend enjoying this product. Save your money. ### 1/5 — Does not pair w cold plunge *2026-08-19, version 4.7* Persistent problems pairing and will not hold temp Hard to navigate to repair dysfunctional plunge ### 1/5 — Eco mode *2026-08-18, version 4.7* Does not function Software is not working properly ### 1/5 — Cold plunge *2026-08-14, version 4.7* This cold plunge sucks!!! Don’t get!!! Buy from someone else!!! The people here so don’t care ### 1/5 — Cold plunge *2026-08-10, version 4.7* This cold plunge sucks!!! Don’t get!!! Buy from someone else!!! ### 1/5 — No customer service *2026-07-22, version 4.7* Honestly you spend thousands of dollars on a product and there is hardly any customer service other than texting!? System keeps dropping out on the WiFi (not the WiFi’s fault, running consistently at 350mpbs). When you get the bath installed you cannot upgrade the firmware. You can’t control it from the app because it drops out every few minutes. Complete waste of money ### 1/5 — Very Delayed Support *2026-06-26, version 4.6* After investing over $10,000 into this bathtub, we are still waiting for PLUNGE Support to email us back why our PLUNGE cannot seem to stay on. We have an email that is asking for metrics which we don’t have access to because the electrical system for the PLUNGE is down. Very disappointing. PLUNGE support emails are not monitored with any frequency apparently. If we had known better, we should have returned this unit within 30 days. Now we are stuck with this horrible investment and we are at the mercy of PLUNGE Support. If we do not have the unit fixed using the warranty system, then no future damage will be covered under warranty. We are being held hostage. Caveat Emptor ### 1/5 — No Centigrade option? *2026-06-21, version 4.6* Bit of an oversight? ### 1/5 — Worst customer service on earth *2026-05-05, version 4.6* First and foremost. The product works. When you use it; you will become addicted. I can’t even begin to explain how bad of support the company has. I bought a second plunge after my first one crapped out. They had a faulty system and my internet didn’t ping to the plunge so they voided my warranty. After a month of emails back and forth (they won’t talk on the phone) I went to the COO and head of customer relations. They finally got back to me. Now I am here sitting for a week and a half trying to schedule a technician to install a new chiller (prepaid the $750 technician visit) and no timeline in sight. The entire process has been one of the most maddening experiences of my life. I have contemplated getting my attorney involved because the product is so good. It is a catch 22 but don’t fall in love because once it goes out (which it will) you are in serious trouble. ## Most praised reviews (10 highest-rated) ### 5/5 — Cool!

Amazing way to get cold and energize my day! ### 5/5 — Cold plunge review *2025-10-07, version 3.6* Best purchase I’ve ever made for my health and attitude to start my day . ### 5/5 — Absolute game changer *2025-08-27, version 3.5.2* There are loads of cold plunge and sauna companies, but Plunge is the only one with a (really good) app that not only makes the experience of using these products so much more convenient – from starting and tracking sessions to getting maintenance reminders – but also teaches you a lot about contrast therapy along the way. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
