Assembly, foundation and delivery
- Barrel saunas need a level, well-drained base that supports the cradles along their full length — confirm the seller's foundation guidance before ordering.
- Electric sauna heaters of this size are hardwired to a dedicated 220–240V circuit by a licensed electrician — never plugged into a standard outlet.
- Breaker size and wire gauge must come from the heater manual shipped with the unit; ask the seller for it before ordering.
- Check local permit and property-line setback rules before choosing the spot.
