1. Choose your format
The main formats in the UK are fixed saunas on a beach, harbour, lake or garden site, mobile or trailer saunas that move between pitches and events, floating saunas on a pontoon, and urban bathhouses indoors. Each has different costs, permissions and seasons. Fixed sites build regulars, mobile saunas reach more places, and urban sites are less exposed to weather.
2. Secure a site and check permissions
Talk to the landowner first, whether that's a council, harbour authority, estate or private owner. Ask your local council early about planning, licensing for any food or drink, and trading consent for public spaces, as rules vary between areas. Get public liability insurance in place before you open, and keep a written risk assessment covering heat, cold water, fire and the stove.
3. Decide how you'll sell sessions
Most UK saunas sell social seats in a shared hour and private hire for groups. Add memberships once you have regulars, and gift vouchers before your first Christmas. Read our guide to pricing sauna sessions.
4. Set up online booking before you open
Guests expect to book and pay online, choose a time and get a reminder. Choose a system built for shared seats, so you never oversell an hour. Look for card and Apple Pay payments, reminders, vouchers, and a way to fill last-minute gaps. Our guide to choosing sauna booking software has a checklist.
5. Get found
Create a Google Business Profile with your exact location, photos and opening hours. Make sure your website says clearly where you are, what a session includes, how long it lasts and what it costs, so people and AI assistants can answer questions about you. Instagram is where most UK sauna communities gather, so post the sunrises.
6. Plan for the seasons
Many outdoor saunas are busiest from autumn through spring, when cold-water swimmers are out. Use cheaper off-peak prices, memberships and vouchers to smooth out the quieter weeks, and last-minute alerts to fill gaps.
7. Look after your regulars
Regulars become members, members bring friends, and friends buy vouchers. Remember names, ask for reviews, and give members first access to busy dates.
