How do I set shared-capacity seats on a sauna or cold plunge session?

Capacity is per-slot seats with ceiling from event, space, and slot; sauna and cold plunge are usually separate spaces.

ZettlorUpdated August 26, 2026

Each slot has a seat count; effective capacity is the ceiling across event, space, and the slot. Shared-capacity sessions use concurrent seat limits on overlapping slots on the same space or location.

What Zettlor does today

Sauna barrel and cold plunge pool are separate spaces with independent seat counts unless you attach both to one shared resource, which is unusual. Buyouts use a space buyout lock. Overlapping slots on the same space share concurrent seat limits, not separate appointment calendars.

This behavior is live in Zettlor today for a commercial sauna and cold plunge room. Guest booking, cancel, and credit self-serve steps stay on Help. This page is for operators.

Desk path

Scheduling → Configuration for seats per slot; Schedule capacity override for one-off changes; event create for event-level caps.

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 set high seats on every overlapping slot and exceed physical room capacity. Concurrent seat limits on the same space cap what overlapping slots can sell together.

Operator example

Rytual sauna space seats 8 and cold plunge space seats 4; each slot respects its space unless both share one resource.

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

  1. Assign sauna and cold plunge to separate spaces with correct seat counts unless intentionally shared.
  2. Set seats on the repeating schedule template or slot for each shared-capacity session.
  3. Check event-level caps when running special events with lower ceilings.
  4. Review overlapping slots on Schedule for concurrent occupancy on one space.
  5. Use a space buyout lock for buyouts that remove shared capacity entirely.

Do sauna and plunge share one seat pool?

Only if you put them on one space or shared resource. Normally each space has its own seats and concurrent seat pool.

How do buyouts affect shared seats?

A space buyout lock blocks other sessions on the locked space for the buyout window.
