Booking software for sauna and cold plunge studios
Timed sessions that many guests book up to capacity, with memberships, bundles, gift vouchers, per-guest waivers and check-in. Built for sauna and cold plunge studios, contrast therapy and recovery studios, and bathhouses.
Free to set up · No subscription · Paid in US dollars through Stripe
TIMED SESSIONS
Built around the session, not the appointment
An appointment tool gives one person the whole slot. A studio sells spaces: many guests book the same timed session, up to the number your space holds, and Session stops taking bookings the moment it’s full. That’s the difference between a sauna reservation system and an appointment calendar.

Shared-capacity timed sessions
Set a capacity and guests book spaces in the same slot until it’s full. Overbooking is blocked at checkout, and a waiting list can tell people when a space opens.
Private hire of the whole space
Add a private hire price and one customer books out the whole session, so nobody else can join it.
Flexible start times
Guests choose how long they stay, such as 30 or 60 minutes, with a start as often as you like. Every start shares the same spaces, so you never sell more than the room holds.
Sauna, cold plunge and contrast therapy
Sell contrast therapy as one session, or run the cold plunge as its own session with its own capacity and prices.

Bring guests back and sell ahead, all from your own booking page.
Memberships
Monthly memberships with a set number of included sessions or a member rate, plus early access to book before everyone else. You choose which sessions each tier covers.
Bundles
Bundles (session packs) are prepaid sessions, like 10 for the price of 8, with the expiry and the sessions you choose. A credit comes off each time the holder books.
Gift vouchers
Sell gift vouchers from your booking page, for an amount or for a session, so a regular can bring someone who’s never been.

WAIVERS AND CHECK-IN
Waivers signed before guests arrive
Per-guest waivers
Each guest signs their own waiver on their own phone, from a link or QR code the booker shares. Returning guests don’t sign again unless you change the terms, and each signature is kept with when it was signed and which version was agreed.
Check-in at the door
Staff open the day’s session on the Bookings page, tap each guest in as they arrive and check that waivers are signed. Install it on a phone or tablet as an app for the front desk.

Frequently asked questions
Does Session work in the US?
Yes. Your studio sets its own country, currency and timezone, and US venues get a 12-hour clock and month-first dates by default. Card payments go into your own Stripe account in US dollars, and Session is already used by saunas in the US as well as the UK, Ireland, Australia and New Zealand.
Can I run cold plunge and sauna sessions together?
Yes. Sell contrast therapy as one session with one capacity, or run the cold plunge as its own session with its own capacity and prices alongside the sauna. Memberships, bundles, waivers and check-in work the same way on both.
How much does Session cost?
It’s free to set up, with no subscription. Session charges 0.5% per paid booking, capped at US$150 a month, and free bookings carry no fee. Stripe’s card fees are separate and are paid from your own Stripe account.
Can guests sign waivers before they arrive?
Yes. With one signature per guest, the booker signs at checkout and shares a link or QR code, so everyone else signs on their own phone before the session. Staff can check who has signed at check-in.
Can I sell memberships and bundles?
Yes. Sell memberships with included sessions or a member rate, bundles of prepaid sessions, and gift vouchers, all from your own booking page.
Can I move my bookings over from Acuity or Mindbody?
Yes. You can import bookings, customers and vouchers from Acuity, Mindbody or any CSV. Moving off Acuity has its own step-by-step guide.
Does Session work for a recovery or wellness studio?
Yes, if you sell time in a shared space. Contrast therapy, sauna, cold plunge and other recovery sessions that several guests book at once all work the same way: a timed session with a set number of spaces, plus memberships, bundles and per-guest waivers. Session isn’t built for one-to-one treatments such as massage, or for a therapist’s diary, so a studio that mostly sells appointments will want an appointment tool for those.
