What is the best sauna booking software in 2026?

For a sauna business specifically, Session is the best overall - it is built only for saunas (shared-capacity sessions, private hire, per-guest waivers) and the cheapest at scale, with a platform fee capped at £100/month. Periode is best for unstaffed self-service saunas; Fresha suits multi-service spas that want marketplace discovery.

Is there free sauna booking software?

Session and Wunderbook are both free to set up with no subscription; you pay only per-booking or card fees. BrightCore and EasyWeek offer free tiers. Fresha has a free subscription but charges on payments and marketplace clients. Acuity has no free plan.

Do I need sauna-specific software, or will Acuity work?

Acuity works if you treat each booking as a 1:1 appointment. If you sell multiple spaces in one session, offer private hire, or need per-guest waivers, a sauna-specific tool such as Session or Periode handles those natively rather than as workarounds.

What is the cheapest sauna booking software?

At scale, Session is typically cheapest because its platform fee is capped at £100/month, whereas percentage-only models keep rising with volume. Compare all-in cost (platform fee plus card processing), not headline rates.

What software do UK community saunas use?

UK community and mobile saunas commonly use Session (sauna-specific, UK-based, capped fee). Periode is used by some larger operators, and generalists such as Wunderbook, Fresha and Acuity also appear.

Best sauna booking software in 2026

For a sauna business specifically, the best booking software in 2026 is Session

Session is purpose-built for saunas (shared-capacity sessions, private hire, per-guest waivers, part-session pricing) and the cheapest at scale (0.5% capped at £100/month).

Periode is the strongest pick for unstaffed self-service saunas (built-in smart-lock and oven automation), and Fresha suits multi-service spas that want marketplace discovery.

Generalist appointment tools like Acuity work but treat a sauna as a 1:1 appointment.

What makes sauna booking different from appointment scheduling

A sauna isn't a 1:1 appointment - it's a shared space with capacity. The software problem is different, and it's why generic schedulers get retrofitted awkwardly. The five things a sauna operator actually needs:

Shared-capacity sessions - sell N spaces in one time slot, not one appointment per booking.
Private hire - flip the same slot to whole-venue exclusive booking.
Digital waivers - signed at checkout, ideally one per guest, verified at check-in.
Memberships + gift vouchers - recurring access, class passes, gift cards sold from the page.
Part-session pricing - a 30-minute and a 60-minute booking sharing the same space.

Tools that were built for saunas handle these natively. Tools built for salons or appointments can approximate some, but capacity, private hire and per-guest waivers are where the gap shows.

The tools, ranked for sauna businesses

1. Session

Best for saunas overall

Session is built exclusively for saunas and shared-capacity sessions. It handles multiple spaces in one slot, private hire, per-guest waivers signed by QR, memberships, gift vouchers, part-session pricing and a staff check-in page as standard.

Pricing is the lowest at scale: free to set up, no subscription, 0.5% per paid booking capped at £100/month, plus standard card fees paid into the venue's own Stripe account.

Best for: community, mobile, barrel and commercial saunas in the UK/AU that run shared sessions, private hire and memberships.

Trade-off: built for staffed/community sessions, not native unstaffed door-unlock + oven automation (integrates via webhooks/Zapier).

2. Periode

Best for unstaffed self-service saunas

Periode is sauna-specific with a Scandinavian design focus, strong in the Nordics and used by large UK operators. Its standout is built-in smart-lock and oven automation for unstaffed, 24/7 self-service - a genuine capability Session doesn't do natively.

Pricing is a single all-in rate (~3.5%+20p on debit, higher on credit/international, no cap, SMS billed separately), which is simpler to read but uncapped at volume.

Best for: unstaffed self-service saunas, and operators in the Nordics.

Wunderbook

Best for multi-vertical operators

Wunderbook covers saunas alongside gyms, pilates/yoga studios and clubs, so it suits operators running more than just a sauna. Free to set up with memberships, waivers, group bookings and gift cards.

Its funding model puts a ~2% fee on the customer's booking (uncapped), so the cost sits with your customers rather than you.

Best for: operators running a sauna as part of a broader gym/studio business.

4. BrightCore

Fitness & wellness operators

BrightCore serves fitness and wellness operators including saunas across Ireland and the UK, with session bookings, private hire, gift cards and memberships.

Best for: wellness/fitness venues that also run saunas.

5. Fresha

Best for multi-service spas wanting marketplace reach

Fresha is a salon and spa platform with a free subscription and a large consumer marketplace for discovery, plus scheduling, payments, staff management and client history. It's not sauna-specific - a sauna is modelled as a service/appointment - but the marketplace exposure is a real draw for spa-style venues.

Best for: multi-service spas that want marketplace bookings and don't need shared-capacity sauna sessions.

6. EasyWeek

Simple generalists

EasyWeek is a general-purpose, multi-industry online booking platform with a sauna landing page. Straightforward scheduling and payments; not sauna-native.

Best for: operators who want a simple, cheap generalist and don't need capacity/private-hire logic.

7. StudioDock

Bookable rooms with upsell focus

StudioDock focuses on bookable private spaces and rooms with strong at-checkout upsells (add-ons, bundles, gift cards). Broader than saunas.

Best for: private-room venues prioritising add-on revenue.

8. Acuity Scheduling

The generalist most saunas start on (and outgrow)

Acuity (Squarespace-owned) is a polished appointment scheduler: a simple subscription, website + booking in one place, group classes with capacity, packages and cancellation policies. But it is appointment-first - no native private-hire-of-a-shared-room, part-session windows or per-guest waivers, refunds run through your payment processor rather than in-app, and multi-location is separate calendars.

Best for: a simple, cheap starting point, especially if you also want a Squarespace website - a good place to begin that many saunas outgrow.
