Choose the Right Location

Select a stable, level location with sufficient clearance for assembly and access. Be sure the area allows for proper drainage and has convenient access to electricity. Thoughtful site selection helps ensure safe operation and long-term durability.

Check Local Building Requirements

Depending on your location, a building permit or HOA approval may be required to build a sauna. Always check local regulations before installation.

Hire an Electrician

A trusted licensed electrician must be hired to install your sauna heater. Sauna heaters do not plug in to standard outlets and must be hardwired to your electrical panel.

Concrete pad or concrete footings under each sauna cradle
