Pros & cons
Plunge Original
- ✓True plug-and-plunge setup — most owners are in cold water the same day it arrives
- ✓105-gallon tub fits users up to 6'8" with full-body immersion
- ✓Ozone plus filtration keeps water clear for weeks between changes
- ✓Massive owner community means every problem has a documented fix

- ✗Perpetual discount pricing makes the 'list price' feel artificial

Inergize Cold + Hot Plunge
