Plunge All-In Gen 2

The Plunge All-In Gen 2 is a self-contained cold plunge tub with an integrated chiller and heater, so a single unit delivers both cold immersion at 37 degrees F and warm soaking up to 104 degrees F. Fill it with a garden hose, plug it into a standard 120V 15A dedicated outlet, and the system cools and maintains your water automatically. No plumbing and no ice are required. You can explore it alongside the rest of our cold plunge collection.

After you fill the tub with tap water, the integrated chiller brings the water down to your target temperature over the course of several hours, depending on your starting water temperature and the surrounding conditions. The Gen 2 cools up to 31 percent faster than the original model, so the initial wait is shorter. Once the water reaches temperature, the system holds it automatically, so your plunge stays ready for your next session.

The Plunge app connects over Wi-Fi and lets you set precise temperatures, build daily or weekly schedules, track your session history, and receive maintenance reminders, all from iOS or Android. It is built on insights from more than 45 million cold plunge sessions across the Plunge community. Many owners value pre-cooling or pre-heating the tub remotely so it sits at the perfect temperature the moment they are ready to step in.

The Plunge All-In Gen 2 is a residential-grade unit purpose-built for daily personal or household use. With true plug-and-play setup, double filtration that cycles the full 105-gallon volume every 15 minutes, and continuous ozone sanitation, it suits the dedicated individual or family building a daily recovery practice at home. For a high-traffic gym or spa, Plunge offers a separate Commercial Max line. Browse more options in our cold plunge collection.

The Gen 2 keeps water clear with a double filtration system that cycles the full 105-gallon volume every 15 minutes, paired with continuous ozone sanitation.
