WHEN PEOPLE GO
Sunday is the big day
At four in five saunas, weekend sessions fill better than weekday ones, typically by about a fifth. Sunday is the single fullest day at nearly half of saunas. Friday is usually the quietest.
If you’re deciding where to add sessions, weekends are the safe bet. If you’re trying to fill the quiet ones, midweek and Friday are where a lower price or a members-only session has the most room to work.

Mornings, afternoons and evenings fill at much the same rate - the day of the week makes more difference than the hour. Early starts before 9am are the exception: they’re a small share of sessions and fill less well.

Four in five bookings are for a session of an hour or less, and almost none run past 90 minutes. If you run longer sessions, say clearly what the extra time gets them.
HOW PEOPLE BOOK
Sauna is a last-minute decision
Almost half of bookings are made less than a day before the session. Only about one in seven is made more than a week ahead.

Weekend sessions get booked a little further out than weekday ones, but not by much.
Cancellations are rarer than operators fear
2 in 100
bookings get cancelled at a typical sauna
Even at the high end it’s about 1 in 20, and fewer than 1 in 100 are cancelled in the last 24 hours. For most saunas, cancellations are not what makes or breaks a week.
Don’t panic early
A session that looks half-empty the day before can still fill.
And whatever people see when they check on the day - your booking page, your social posts - is where most of your bookings are won.
HOW FULL SAUNAS GET
Most saunas have room to grow
The typical sauna fills about a third of the spaces it puts on sale across the year, and about one in three saunas averages half full or better.

Typical sauna: about a third full
Middle half of saunas: a sixth to two thirds full
7%
of sessions sell out at a typical sauna
So if your weekday sessions feel quiet, you’re in good company. Weekends fill first at most saunas, so that’s where extra sessions are most likely to sell.
Groups are already half the demand
46% of bookings are for two or more people, and a third are pairs. A small discount for a second person is one of the easiest ways to raise what each booking is worth.

Six is the most common size, but a quarter of saunas seat thirteen or more.
Price per space sits in a narrow band while capacity doesn’t, so what decides revenue is how full each session is, not the headline price.
Private hire
£95
typical private hire · ≈ $127 · €111
Most private hires fall between £70 and £120. The sessions actually booked privately hold about six spaces, so a full private hire works out at roughly £16 a head, about the same as selling six single spaces.
≈ £16 a head
A private booking takes the whole sauna however many people come, so compare it with a full session of singles. If your private hire costs less than that, you’re charging less for the whole sauna than it earns when it’s full.
GETTING PEOPLE BACK
72%
of customers visit once in twelve months and don’t come back
Only 5% reach a fifth visit. For most saunas the biggest opportunity isn’t finding new customers, it’s getting the ones you already have to return.
Bundles
1.7×
as often as other customers, and three times as likely to reach a fifth visit
Two in three saunas sell a bundle. Most are packs of five or ten, with a typical saving of 18%, and nearly all come with an expiry date.
Some of that is people who were already regulars choosing to buy a bundle, so treat it as a sign of which customers to look after, not as proof that bundles create them.
Memberships
Members
7.7
Everyone else
1.6
Visits a year
Just over half of saunas sell one, and four in five tiers include a set number of sessions. A typical membership is £40 a month (≈ $54 · €47) for four sessions, against about £60 (≈ $80 · €70) one at a time. Members are under 2% of customers but make up 8% of visits.
People who already come often are the ones most likely to join, so don’t expect a membership to turn occasional customers into regulars. Treat it as a way to look after the regulars you already have.
Win-back emails
11%

It costs nothing to send once it’s set up, and it goes straight at the 72% who otherwise never return.
How we measured this
Every figure is an aggregate of real bookings. We’ll update these figures each year.
Who’s included
Live saunas on Session that take payments in pounds. Figures from different currencies can’t be meaningfully averaged, so saunas outside the UK aren’t included in this edition.
Period
Sessions and bookings over the twelve months to September 2026. Prices as on sale in September 2026.
Per sauna, then typical
How full saunas get, which days fill best and how often bookings are cancelled take each sauna’s own figure first, then the typical sauna, so one very busy sauna can’t outweigh the rest. Saunas with too few sessions are left out of these.
Per booking
How far ahead people book and how long sessions run count every booking.
Prices
What customers can actually buy on each sauna’s booking page, not every price an operator has ever set up.
“Typical”
The middle value, so a handful of unusual saunas don’t skew it. “Most common” means exactly that.
Conversions
Dollar and euro figures use European Central Bank rates from 21 September 2026. They’re conversions, not observed prices.

Frequently asked questions
When are saunas busiest?
Weekends. At four in five saunas, weekend sessions fill better than weekday ones, and Sunday is the fullest day at nearly half of saunas. Friday is usually the quietest day, and time of day makes less difference than the day of the week.
How far in advance do people book a sauna?
Mostly at the last minute. Almost half of sauna bookings are made less than a day before the session, about one in six within three hours, and only about one in seven more than a week ahead.
How long is a typical sauna session?
An hour. 60 minutes is the most common session length, used by two in three saunas, and four in five bookings are for a session of an hour or less.
How much does a sauna session cost?
In the UK, the most common price for one space in a shared sauna session is £15 (about $20 or €17). About three in four saunas charge a typical price of between £12 and £19 for a single space. Typical private hire of a whole sauna is about £95.
How much is a sauna membership?
A typical sauna membership is about £40 a month (about $54 or €47) for four sessions, against about £60 to buy four sessions one at a time. Four in five membership tiers include a set number of sessions rather than just a discount.
How often do sauna customers come back?
72% of customers visit once in a year and don’t return, and only 5% reach a fifth visit. Members visit about 7.7 times a year, against 1.6 for everyone else.
