Booking software for mobile saunas
Session is booking software for mobile, trailer, horsebox and pop-up saunas that move between pitches: one account, a booking page for each pitch, times you set around the tide, and private hire on the same calendar.
Free to set up · No monthly subscription · Paid in your own currency through Stripe

WHEREVER YOU’RE PARKED
One account, every place you pitch
Add each beach, lido or field you pitch at as a location. Guests pick a location at the top of your booking page and only see the times there, and each location gets its own page you can put on a flyer, a QR code by the sauna or your social profiles.
Move one session between places by changing where a date runs, and archive a pitch when you stop going there - its past bookings stay in your reports.

MOBILE SAUNAS ON SESSION
Mobile saunas already booking on Session
From the Isle of Arran to South Australia, trailer and pop-up saunas run their pitches on Session. In their own words, from their reviews.


Stonesthrow Sauna
Isle of Arran · 3 sites
“Session makes scheduling sessions the work of half an hour, when it used to take half a day.”
Amy Wegerhoff, Company Director
See their booking page →


Hotbox Sea Sauna
Benone Strand and Groomsport Harbour
“It’s easy to use and the layout of everything is clear and concise - both from the office and the guest side.”
Anna Isaksson, Owner
See their booking page →


Sauna Uno
Pembrokeshire
“In quiet months the fees are low, and in busy months you know you won’t pay more than £100.”
Renny V, Manager
See their booking page →


Salted Barrel
South Australia · 5 pop-up sites
“Knowing that Session is managing our bookings 24/7 while I can focus on actually running the business has been fantastic.”
Sarah W, Mobile Sauna Owner

TIDES, WEATHER AND CHANGING TIMES
A schedule that moves when you do
Mobile saunas rarely run the same week twice. Set a weekly schedule where you have one, and add everything else as dated sessions: a range of back-to-back starts in one go, a festival weekend at its own price, or a sunrise session that only opens to book a few days before.
One-off sessions and events →
Hide a date or close a day
Hide a date to stop new bookings without cancelling anyone, or close a whole day of regular sessions, for a travel day or a broken stove.
Move a regular time
Move a regular time by up to an hour and Session emails everyone booked. You choose whether they can cancel for a full refund, credit, or under your usual policy.
A waiting list for full sessions
When a space opens, the waiting list tells people, so a cancellation on the beach doesn’t go empty.
Tell regulars where you’ll be
An announcement at the top of your booking page tells regulars where you’re pitched next.
PRIVATE HIRE, PARTIES AND EVENTS
Private hire on the same calendar as your social sessions
Birthdays, hen parties, team days and wedding mornings often book the whole sauna. Add a private price to any session and one group books it out; the date then shows as fully booked, so it’s never sold twice.
Book out the whole sauna
A private price on any session. Once a group buys it, nobody else can join that date.
Price by group size
Add a price per size, such as 2, 4 or 6 guests, or sell a “bring a friend” block that leaves the rest of the session open.
Events at their own price
For a full day at a festival or a retreat, create a one-off session with an agreed private price and send the client its link to book and pay.
How private hire works →
Session sells time in your sauna. Hiring the trailer out to a customer’s address for a weekend isn’t a booking type in Session today.
GIFT VOUCHERS, BUNDLES AND REGULARS
Sell the winter in the summer
Gift vouchers
For an amount, a session or a whole private hire, emailed with a code or printed in your own design with a QR code. A credit voucher works at any pitch.
How gift vouchers work →
Bundles
Prepaid sessions, like 5 for the price of 4, that regulars can use at every pitch or only the ones you choose.
Bundles →
Memberships
Monthly memberships with included sessions or a member rate, and early access to book before everyone else.
Memberships →
Add-ons
Robes, towels and hot drinks sold with the booking, without taking a space.
ON THE BEACH
Every guest’s waiver signed before they reach the sauna
A waiver for each guest
Choose Each visitor signs and everyone in a group signs on their own phone, from a link the booker shares.
Check-in on your phone
Open the session, tap each guest in and see who has signed.
Clear arrival details
Each date can carry its own visit instructions in the confirmation email, like where to park at this week’s pitch.

PRICING
Quiet months cost almost nothing
Free to set up, with no monthly subscription and no contract. Session charges 0.5% per paid booking, capped monthly in your own currency - £100, €90, US$150, A$150 or NZ$170 - and free bookings carry no fee. A month you don’t trade costs nothing, and a quiet winter month with £1,000 of bookings costs £5.
Card fees are Stripe’s standard rates, and payments go into your own Stripe account. The cap is per venue, so extra pitches never cost more, and your cap never goes up as you grow. Operators already taking more than £30k a month in bookings (or the equivalent in their currency) when they join agree a cap with us directly.
On a £15 session
Session (0.5%)
about 8p
Stripe card fee (1.5% + 20p)
about 43p
You receive
about £14.50
Stripe’s standard rate for UK cards on a UK account. Session’s share stops at £100 a month, however busy your summer gets.
Switching from another system
Import your bookings, customers and vouchers from Acuity, Periode or any spreadsheet export, so regulars keep their bundles and vouchers.
Frequently asked questions
Does Session work for a mobile sauna?
Yes. Session is built for saunas that sell time in shared sessions or private hire, and that includes trailer, horsebox and pop-up saunas. Add each place you pitch as a location, add dated sessions when you know where you’ll be, and sell private hire, gift vouchers, bundles and memberships. Mobile saunas in the UK, the US, Australia and New Zealand already use Session.
Can I run my sauna at different pitches?
Yes. Add each pitch as a location with its own address and booking link. Guests choose a location on your booking page and see only the times there, and each location has its own page for flyers, QR codes and social profiles.
My times change every week with the tide. Will that work?
Yes. Skip the weekly schedule and drag across the hours you’ll be open on your calendar’s Week view. Quick add lays out back-to-back starts to add in one click, skipping any times already there.
What happens if I have to cancel for the weather?
Cancel the date and everyone booked is refunded or given credit, depending on your policy, and emailed with the reason you type. To stop new bookings without cancelling anyone, hide the date instead.
Can I sell private hire for parties and events?
Yes. Add a private price to any session so one group can book the whole sauna, or charge by group size with a price per size. For an event at its own time and price, create a one-off session and send the client its link to book and pay.
How much does Session cost for a seasonal sauna?
It’s free to set up, with no monthly subscription. Session charges 0.5% per paid booking, capped monthly in your own currency (£100, €90, US$150, A$150 or NZ$170), so a month you don’t trade costs nothing. The cap is per venue, so extra pitches never cost more, and your cap never goes up as you grow. Operators already taking more than £30k a month in bookings (or the equivalent in their currency) when they join agree a cap with us directly. Stripe’s card fees are separate and are paid from your own Stripe account.
Can I rent my sauna trailer out for a weekend?
Not as a booking type. Session sells time in your sauna, by the session or as private hire, including a full day at an event. Multi-day trailer rentals delivered to a customer’s address need a separate quote and invoice outside Session.
