# Sauna and cold plunge studio software

In a contrast therapy studio, guests rotate between heat, cold, and rest during one visit, and the cold plunge almost always sets the capacity ceiling. Booking the sauna and the plunge as two separate 1:1 appointments creates two reservations for one visit and a queue at the cold tub whenever a session runs long.

## Short answer

Zettlor schedules a contrast studio around physical spaces (`Sauna`, `Cold Plunge`, or a combined contrast room) with concurrent seat limits, staggered arrival waves, and turnaround buffers. The same rooms can sell shared contrast seats, private sessions for two, and full group buyouts from one inventory pool without double-booking, alongside recurring memberships, per-offering digital waivers, front-desk POS on your own Stripe account, and assisted migration.

## When you do not need this

If you rent one sauna and one cold plunge exclusively to a single private party by the hour and never sell shared seats or memberships against capacity, a simple appointment calendar is enough.

## Why generic schedulers break

- **Shared loops, private contrast, and full buyouts on the same rooms**: Generic schedulers split shared sessions and private rentals onto separate calendars. In Zettlor, [shared seats, private sessions, and space buyout locks](/guides/booking/private-vs-shared-same-slot) share one room inventory: a buyout locks the sauna and plunge for that window, and booked shared seats block conflicting buyouts. Private buyouts also support [upfront percentage or fixed deposits with balance collection](/guides/pay/deposit-then-balance), [checkout add-ons](/guides/booking/private-with-add-ons) (towels, plunge tokens, electrolyte add-ons), and [host-paid booking before every guest name is entered](/guides/pay/host-pays-before-names).
- **Per-offering waivers for sauna vs. cold plunge without cart drop-off**: A studio often needs a cold-plunge contraindication acknowledgment alongside a general session waiver or membership agreement. Zettlor supports [multiple separate waiver templates](/guides/desk/more-than-one-waiver) via per-offering `Requires Waiver`, collects payment first so group hosts never abandon checkout, prompts immediately for signatures or [door QR / kiosk signing](/guides/desk/waiver-web-or-door), blocks self check-in until every attendee signs, and shows signed status on each guest row on `Schedule` ([seeing signed waivers](/guides/desk/see-signed-waiver)).
- **Front-desk POS and walk-in checkout on your own Stripe account**: Zettlor connects directly to [your own Stripe account](/guides/pay/own-stripe-account) so payouts, saved cards, and disputes stay in your name. Staff run front-desk POS and walk-ins using saved cards on file, Stripe's in-browser card form (with phone tap-to-pay where supported by the browser), [retail cash on the register](/guides/pay/offline-payment), and [door QR self-checkout](/guides/desk/qr-poster) without requiring dedicated countertop Stripe Terminal hardware ([front-desk card checkout](/guides/pay/stripe-reader)).
- **Assisted migration with staged deduplication and zero re-checkout**: Moving from Momence, Mindbody, Mariana Tek, or Acuity combines team-assisted migration with `Advanced -> Import` and `Advanced -> Migration` staging: customer CSVs are deduplicated by email and phone (`Merge Customer` includes undo), [existing Stripe subscriptions link directly to customer profiles](/guides/membership/port-existing-membership) so active members keep their billing date and card without a second checkout, [remaining punch-pack visits and gift card balances import](/guides/migrate/gift-card-balances), and [future bookings](/guides/migrate/future-reservations) land on repeating room templates before you flip the live calendar ([full migration checklist](/resources/migrating-sauna-memberships-and-credits)).
