• Safe heat and fire handling
• Customer service and hosting
• Scheduling and online bookings
• Basic towing and trailer upkeep

• General liability insurance that covers sauna operation, and check what your insurer needs for towing and fire risk
• Fire rules for wood-fired stoves, burn bans and local permits, so check with your fire department
• Permits for parks, beaches, private land or event vendors, since rules vary by city, county and state
• Guest safety: heat can be risky for some medical conditions, so use a signed waiver and clear safety rules, and avoid making health claims
• Check whether your health department has rules for towels, water or a shared plunge tub
• Towing weight limits and your vehicle's capacity

Startup costs are typically around $15,000 to $50,000, depending on the trailer and sauna build, the stove type and any cold plunge or towing gear. These are estimates, so get quotes before you commit.

Monthly revenue is typically around $1,500 to $7,500, depending on how many sessions and events you book and your pricing. This is an estimate of revenue, not profit, and you would also cover fuel, wood or power, and upkeep.

Check fire rules for wood-fired stoves, burn bans and local permits with your fire department. Also check permits for parks, beaches, private land or events, health department rules, towing limits, and insurance. Use a signed waiver and avoid making health claims.
