Why sauna business's love us!
Sauna businesses love Wunderbook because it takes the steam out of admin and keeps their focus where it belongs — on the experience.
From group bookings and memberships to vouchers and waitlists, everything runs automatically in the background and can be managed right from your phone.
With Apple Pay and Google Pay built in, checkouts are lightning fast — click, confirm, and chill.
Plus, every business shares the same app, meaning saunas tap into a growing community of users already booking nearby gyms, studios, and wellness spaces — bringing new faces through the door without extra marketing.
Simple. Fast. FREE. Just how it should be.

Everything’s in one place, from gift cards to memberships, so they can easily explore new wellness spots and revisit their favorites.
And because every sauna, gym, and studio is on the same app, users get access to a whole community of experiences — all just a tap away. Simple. Fast. FREE. Exactly how booking should feel.

FAQ's
Is it really FREE?
Yes, companies never pay us a penny. We charge a small 2% booking fee to the user, meaning your success = our success.
The only fee your business pays is Stripe’s processing fee: 1.5% + 25¢ per transaction.
To be fully transparent, we’ve created a calculator so you can see the exact cost. Just note, this goes to Stripe, not Wunderbook.
Keep an eye out for platforms that hike up these fees and still charge you a monthly subscription.

Do I need to download the app to book?
No, each company has a Schedule link. This is a direct link to your schedule and profile. You can share it on your Website, Social media or even simply send it as a message or maybe you want to create a QR code.
How long does the set up take?
Set up in minutes. Leave anytime.
No contracts. No commitments. Just register, connect Stripe, and start taking payments. If we don’t add value, walk away – no hard feelings.
Can I have more than 1 account
Absolutely and we actually recommend it. Multiple accounts allow you to take full advantage of our geo-targeting feature, which shows users the businesses closest to them first.
More local visibility = more bookings.
We can also link your accounts for easier management across locations — making it simple to switch, monitor, and grow each business.
