How do I book a sauna plus a treatment add-on in one flow?
Combine sauna or cold plunge access with catalog add-ons in one checkout; separate practitioner treatments need a second offering.
Session checkout supports add-ons from the offering catalog on the same reservation. A treatment sold as a one-to-one practitioner offering is a separate offering and is not automatically chained in one flow.
What Zettlor does today
Add-ons on a shared-capacity sauna or cold plunge offering attach at checkout on one reservation. Practitioner treatments as one-to-one offerings require a second booking unless you sell the treatment as an add-on catalog item on the session.
This behavior is partial: some of it is live, and the rest is a desk workaround rather than a missing settings screen you should hunt for. Guest booking, cancel, and credit self-serve steps stay on Help. This page is for operators.
Desk path
Offering add-on catalog for session extras; separate offering create for one-to-one treatments; Schedule for two bookings if needed.
Do not invent a settings path beyond what is listed here. If the product does not include a control, the desk workaround is the path.
Failure mode
Operators create a one-to-one treatment offering and expect it to bundle into sauna checkout. Guests must complete two flows unless the treatment is an add-on item.
Operator example
Alchemy sells sauna access with a recovery add-on in one checkout; massage as a one-to-one offering is booked as a second appointment on Schedule.
A sauna and cold plunge operator can copy the shape of this example without copying another brand's private pricing or customer lists.
How to do this
- List session extras as add-on catalog items on the sauna or cold plunge offering.
- Test guest checkout: base slot plus add-ons on one reservation.
- For practitioner treatments, decide: add-on item on the session or separate one-to-one offering.
- If separate, book the treatment as a second offering on Schedule or guest flow.
- Align treatment timing with session buffers so slots do not overlap illegally.
Related questions
Can sauna and a massage book in one checkout?
Only if the massage is an add-on on the session offering. One-to-one massage is a separate offering and booking.
How do staff bundle at the desk?
Add add-ons on desk checkout for the session, or create two reservations on Schedule for session plus treatment.
