The Plunge All-In Gen 2 is a self-contained cold plunge with integrated chiller and heater, running the full range from 37 °F to 104 °F in a single unit. Cold immersion and hot soaking come from the same tub — no second installation, no ice.
It's the long one. At 76¾" the All-In accommodates users up to 6'9", which is what separates it from the shorter tubs in the range.
The chiller specification worth reading twice: 0.75 HP, rated to hold 37 °F in a 120 °F ambient environment. A chiller's headline temperature is easy; holding it in an un-airconditioned garage in August is the part that decides whether the tub gets used year-round. Cooling runs at 10–12 °F per hour, and the integrated heater adds 4–5 °F per hour up to 104 °F.
Plunge states the Gen 2 chiller reaches 37 °F up to 31% faster than the previous generation while using 50% less energy — meaningful on a unit designed for daily use.
Water care runs continuously. A double filtration system cycles the full 105-gallon volume every 15 minutes, paired with ozone sanitation. The filter is top-access, so servicing means lifting it out and rinsing or replacing it rather than draining the tub.
The smart system is more substantial than app control. Ten smart sensors monitor the unit, a higher-gain antenna keeps the Wi-Fi connection stable, and the tub receives over-the-air updates. The Plunge app on iOS and Android handles temperature, scheduling, session tracking and maintenance reminders. Scheduling earns its place here: with cooling measured in hours, setting the tub to reach temperature by a chosen time is how a plunge is ready when you are.
Setup is genuinely plug-and-play — fill with a garden hose, plug the built-in 7 ft GFCI cord into a dedicated 120 V 15 A circuit. No plumbing, no plumber. The unit is engineered for quiet operation and rated for indoor or outdoor residential placement.
This is a residential-grade unit built for daily personal or household use. Plunge offers a separate commercial line for high-traffic gym and spa installations.

Before You Buy
Check you have a dedicated 15 A circuit at the intended location. This runs on a standard 120 V outlet, but the circuit must not be shared. The built-in cord is 7 ft, so the tub has to sit close to it — measure before delivery.
Confirm the filled weight against your floor. 1,150 lbs filled. On a slab or garage floor that's fine; on a deck, balcony or upper floor, have the structure checked.
Confirm delivery scope. In-home delivery is included and covers ground-floor placement
Plan for runoff. Water leaves the tub with the user — on a finished floor, plan drainage or a mat.
Confirm outdoor suitability for your climate, particularly freeze protection over winter.
Safety Guidance
A 105-gallon open water container and cold immersion both carry real risk. A protocol matters:
- Keep the insulated cover secured whenever the tub is unattended. Open water in a home is a drowning hazard for young children and pets.
- Never plunge alone. Cold shock response — an involuntary gasp and rapid breathing on entry — can be dangerous in water, and its severity isn't predictable from experience.
- Enter gradually and control breathing before full immersion.
- Limit session duration and watch for shivering, numbness or disorientation on exit.
- Do not use after alcohol or when significantly fatigued.
- Anyone with a cardiovascular condition, high or low blood pressure, arrhythmia, Raynaud's, a seizure disorder, or who is pregnant should consult a qualified physician before cold immersion, as should anyone taking medication affecting heart rate or blood pressure.
- Supervise all first-time users.
