Home sauna & cold plunge buying guides

Sauna vs. plunge: the practical differences
| Home sauna | Cold plunge | |
|---|---|---|
| Main hardware | Wood cabin or barrel, electric or wood-fired heater | Insulated tub, chiller, pump and filtration |
| Typical power | Often a dedicated 240V circuit for larger electric heaters | Many units run on 120V; some chillers need dedicated circuits |
| Site prep | Level foundation, clearances, weather protection outdoors | Level surface, drainage access, shade or cover outdoors |
| Ongoing upkeep | Wood care, heater stones, occasional element replacement | Water changes, filters, sanitation, chiller maintenance |
Always confirm requirements against the specific model's install manual and your local code.
Our approach
