Sauna and cold plunge booking software that speaks your language

Fitness software can work for wellness — with the right customization

Sauna and cold plunge studios are wellness businesses, not fitness gyms. But most software was built for group fitness and doesn't let you change a single word. Your clients don't "register for a class" — they "reserve a session." Your staff aren't "instructors" — they're "guides" or "technicians." Forcing your studio into someone else's vocabulary is a small friction that adds up to a big brand mismatch.

Zipper is sauna and cold plunge booking software with a built-in Hotwords feature that lets you rename terminology across your entire reservation experience — from "class" to "session," from "instructor" to "guide," from "register" to "reserve." Your clients see language that fits your studio, not language borrowed from a spin class app. Everything else — session scheduling, memberships, automated communications, and a branded booking experience — works exactly the same.

Session memberships and recovery packs

Recurring wellness memberships, session packs, and custom pricing — all in one billing system.

  • Sell monthly recovery memberships with a fixed number of sessions per month
  • Offer session packs that auto-renew when clients use their last reservation
  • Create intro offers for first-time visitors with a discounted first session
Marketing between sessions

Automated client communications that build recovery routines — and fill your schedule.

Wellness clients who come once a month are nice. Wellness clients who build a recovery ritual and come twice a week are your business. Zipper's automations send the right message at the right time — turning one-time visitors into regulars without you manually following up with every single person.

  • Post-session follow-ups that invite clients to book their next reservation
  • Re-engagement campaigns for clients who haven't visited in 2+ weeks
  • Intro offer sequences that convert first-timers to members
  • Milestone rewards when clients hit session streaks
  • Unified Inbox for email, SMS, and social DMs in one place

More revenue, fewer tool subscriptions, less tech stress.

Zipper is sauna and cold plunge booking software that replaces your reservation platform, email tool, website, and lead management with one system designed for how wellness studios actually run today.

    Launch a beautiful, fully branded website built to convert visitors into bookings — or keep your existing site and drop in Zipper booking widgets to add scheduling, memberships, and checkout anywhere. Your call.

FAQ

Sauna and cold plunge studio owner FAQs

What is sauna and cold plunge booking software?
Sauna and cold plunge booking software is a reservation platform built for the way wellness studios actually run — timed session reservations for individual sauna bays or plunge pods, recurring recovery memberships, session packs, guided contrast therapy appointments, and automated client communications. Zipper is purpose-built for sauna and cold plunge businesses, with customizable Hotwords terminology so your booking experience uses your language ("session," "reserve," "guide") instead of generic gym vocabulary.
Can I set up timed reservations for sauna or cold plunge pods?
Yes. Sessions can be set to a specific duration with configurable capacity — for example, a 45-minute infrared sauna reservation for one person, or a 30-minute contrast therapy session for two. Clients book a specific time slot, and the booking system prevents double-booking for each space.
How do session memberships work for a wellness studio?
You can create monthly memberships that include a fixed number of sessions per month — for example, "8 sessions per month" that resets automatically on the billing date. You can also offer bottomless session memberships (unlimited monthly) or session packs that auto-renew. Whichever model fits your business, Zipper handles the billing automatically.
Can I offer guided contrast therapy sessions alongside self-directed sauna reservations?
Yes. Guided sessions with a staff guide and self-directed reservations can coexist on the same schedule with different pricing, capacity, and booking rules. Clients see the type of experience clearly when booking.
I'm switching from another platform. How hard is the migration?
Most studios are fully migrated in 1–2 weeks. We handle importing your client and member lists and transfer saved Stripe payment data so clients don't need to re-enter their cards. A dedicated onboarding rep guides you through every step.
How does marketing automation help a sauna and cold plunge studio?
The biggest opportunity is building recovery routines. Post-session automations invite clients to book their next visit. Re-engagement campaigns go out when someone hasn't been in for two weeks. Membership-to-pack upgrade sequences convert drop-in visitors into recurring members. All of it runs automatically.
What does Zipper cost?
One transparent monthly price, billed month-to-month, with no contracts and no add-on fees. Payment processing runs at standard Stripe rates with zero markup on our Growth plan and above. See current pricing at joinzipper.com/pricing.
Can I use my existing website with Zipper?
Yes. Embed Zipper booking widgets into any existing site, or use our included website builder for a fresh start. Either way, your session reservation experience is branded to your studio — with your custom terminology throughout.
