Booking software for cold plunge facilities in the UK

What cold plunge venues need from booking software

Cold plunge and contrast therapy venues are growing fast across the UK. Sessions are short but capacity-limited — one tank, a handful of people per slot, strict turnover for safety and hygiene.

Clients book online for specific time slots, often combining cold plunge with sauna or breathwork. Your booking tool should handle session capacity, waiver collection, and passes for regular users.

Session slots and capacity

• Fixed-duration plunge sessions with capacity per slot.
• Contrast packages combining cold plunge and sauna.
• Intro sessions for first-timers with longer briefing time.
• Block cleaning, maintenance, and water treatment windows.
• Peak and off-peak pricing via separate services or promo codes.

Passes, memberships, and first visits

Regular plungers buy monthly passes or multi-session packs. Prepaid passes on Individual and Team let members book without paying each visit.

First-time sessions need extra time for safety briefings. Create a longer intro service with clear notes about what to bring and health considerations.

Prepayment and deposits

Session slots are limited — a no-show blocks someone else from the tank. Prepayment at booking or a deposit holds the slot seriously.

Sway supports online payments on all plans. Membership passes reduce admin for your regular community.

Growing beyond word of mouth

Many cold plunge venues start with referrals and a Google listing. A booking link on your website, Instagram bio, and Google Business Profile turns interest into confirmed appointments — and as Sway grows, clients can discover you on the platform too, without marketplace commission.
