Buyer's Guide: Cold Plunge Setup
- Chiller vs Ice Loading: Tub units with motorized chillers hold constant temperatures without ice, whereas basic insulated barrels require manual ice bag additions.
- Filtration Systems: Ozone generators and 20-micron filters prevent bacteria growth and reduce necessary water drain cycles.
- Drainage & Placement: Ensure your outdoor deck or concrete pad supports 800–1,200 lbs when the tub is filled with water and an occupant.
