Electrical work: most traditional saunas need a dedicated 240V circuit — typically several hundred dollars, more if your panel needs upgrading ($1,000–$3,000).
Site prep: outdoor saunas need a level base — gravel, pavers or a concrete pad.
Permits & inspections: vary by city; your installer handles them.
Running costs: a typical home sauna session costs roughly $0.50–$1.50 in electricity.
Labor: contractor labor generally runs $45–$200/hour on top of materials.
