Cold Plunge All-In Gen 2

Plunge All-In Gen 2: The Smartest Cold Plunge Tub for Home Recovery

You've committed to the cold. You've felt the surge of clarity, the deep calm that follows, the way your body rebounds faster after every session. But filling a tub with bags of ice, wrestling with inconsistent temperatures, and dealing with murky water? That's not a wellness ritual — it's a chore. The Plunge All-In Gen 2 eliminates every friction point between you and the transformative benefits of daily cold therapy, delivering a self-contained, app-controlled cold plunge tub that's engineered for the dedicated home recovery enthusiast.

Cooling 31% faster and consuming 50% less energy than its predecessor, the Gen 2 represents the most refined residential cold plunge system Plunge has ever built. From 37°F ice-cold immersion to 104°F hot therapy — all from a single unit, no plumbing required — this is cold and hot contrast therapy, perfected for your home.

• Reach target temperature faster — Upgraded chiller cools to 37°F up to 31% quicker than Gen 1, so your plunge is ready when you are
• Cut energy costs in half — Redesigned efficiency uses 50% less energy, keeping your utility bill in check even with daily use
• Control everything from your phone — Wi-Fi-enabled app lets you adjust temperature, set schedules, track sessions, and manage maintenance from anywhere
• Crystal-clear water, minimal effort — Double filtration system cycles the full 105-gallon volume every 15 minutes, paired with ozone sanitation to keep water pristine
• Hot and cold in one unit — Seamlessly shift between 37°F cold therapy and 104°F hot soaking for contrast therapy without a second installation
• True plug-and-play simplicity — Fill with a garden hose, plug into a standard 120V 15A dedicated outlet, and you're ready. No plumber, no ice runs, no hassle
• Whisper-quiet operation — Engineered for indoor or outdoor placement without disruptive noise, so it fits gracefully into any wellness space
• HSA/FSA eligible — Use your pre-tax health savings to invest in daily recovery

What Makes the Plunge All-In Gen 2 Stand Out

The home cold therapy market has exploded, but most products force you to choose between convenience and performance. The Plunge All-In Gen 2 refuses that compromise. Its integrated chiller and heater system means you never touch a bag of ice or wait for a separate heater to warm your water. The app — built on data from over 45 million cold plunge sessions — transforms your tub into a smart wellness device, letting you pre-schedule morning plunges from bed, monitor water quality, and track your consistency over time.

The top-access filtration design makes routine maintenance refreshingly simple. Pop the filter, rinse or replace, and you're done. Combined with continuous ozone sanitation, most users find water changes are infrequent and upkeep is minimal — a stark contrast to the constant draining and scrubbing that cheaper alternatives demand.

This is a residential-grade unit purpose-built for daily personal or household use. If you're outfitting a commercial gym or spa with heavy traffic, Plunge offers their Commercial Max line for that. But for the dedicated individual or family committed to making cold therapy a daily practice at home, the Gen 2 is the gold standard.
