Built for saunas, no workarounds

Most booking systems were built for hairdressers or yoga teachers, with a sauna shape forced on top. Session was built around how saunas actually run.

Schedule once

Full-page editor with a live preview of exactly what your customers will see. Repeat schedules every N weeks, one-off dates, per-instance overrides.

Flexible pricing

Memberships, bundles, gift vouchers, add-ons, 30-min sessions - configured in one place. Sliding scale and concessions built in properly.

Manage your day

Booked-count grid, colour-coded by session type. Spot a quiet session before it runs empty.

Multi-space booking

A single ticket can take 1, 2, or all 8 spaces. Group bookings, family tickets, private hire — without the workarounds.

Waiver per visitor

Each visitor signs their own waiver via a shareable link or QR code, instead of the booker signing for everyone.

Flexible membership

Whether you offer 4 free sessions a month, or 50% off all bookings, you can configure memberships your exactly as needed.

Multiple locations

Run more than one sauna under one login, with one customer base and per-location schedules.

Reporting overviews and details

Revenue trends, occupancy by session, weekly heatmap. CSV exports for accounting and end-of-month

A booking page that just works

Fast, branded, mobile-first. No forced sign-ups, no clunky calendars, no "please contact us to cancel."

Your own brand

Your logo, your colours, your contact details on every email.

A custom web app

Installs as a branded mobile app — no app store fees, no developer.

Full self-service

Customers reschedule, modify, or cancel - all by themselves.

Switching is easy.

Upload a CSV export from your current system and Session brings across your bookings, guests and vouchers. No data lost, no awkward gaps.

Most operators switching to Session have been on a generic booking tool — one that wasn't built for saunas. The difference tends to show up in the same places every time.

Built by a sauna operator

Hi, I'm Wil. I'm a startup founder and product designer, setting up Cardiff Community Sawna — a not-for-profit community sauna.

Every feature in Session exists because we needed it ourselves, or because an operator asked for it. We're doing this to make good, fairly priced software for the sauna community.

Get in touch, I love a chat!
