How do private hire and shared drop-in share the same sauna slot without double-booking?

Private hire and shared drop-in sell against the same sauna or cold plunge space inventory: exclusive private or buyout claims lock that space for the window, and shared seats draw from concurrent seat limits so two modes cannot oversell the room. What does not happen is a second appointment calendar that ignores the first—one physical room stays one capacity pool.

What Zettlor does today

Zettlor natively supports shared sessions, private sessions, and private buyouts on the same rooms. Shared seats fill up to the space or slot seat count; private offerings sell exclusive access for a duration; a space buyout lock closes other bookings on the locked space for that window. Overlapping slots on the same space share concurrent seat limits rather than separate appointment calendars. Dual-mode calendars (shared rows beside private rows) are live; this guide explains how shared and private modes share one inventory pool so you do not double-book the same sauna or cold plunge space.

Guest booking, cancel, and credit self-serve steps stay on Help. This page is for operators.

Desk path

Scheduling → Configuration for shared vs private session types on the sauna or cold plunge space; seats per slot and concurrent capacity on overlapping slots; space buyout lock when a full exclusive claim must remove shared inventory. Schedule to verify private rows and shared seats do not oversell the same window.

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 publish a shared drop-in grid and a private hire grid as if they were two rooms. Guests book both. Staff refunds and rearranges mid-shift. The failure is treating private hire as a second calendar instead of an exclusive claim on the same space inventory that shared seats already draw from.

Operator example

Bad Sauna runs one eight-seat barrel and one cold plunge circuit on the same evening block. Shared drop-in sells individual seats until the concurrent cap is hit. When a couple books a private hire hour on that barrel, the buyout or private exclusive claim removes shared inventory for that window so walk-ups cannot also take barrel seats. Plunge seats stay on their own space unless both resources intentionally share one pool.

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. Put the sauna barrel and cold plunge on separate spaces with correct seat counts unless you intentionally want one shared pool.
2. Enable shared and private session types on the space that should run dual-mode during public hours.
3. Set seats on the repeating schedule template or slot so shared drop-in cannot exceed physical capacity.
4. Use a space buyout lock (or private exclusive offering) when one group must own the whole room for that window.
5. Review overlapping slots on Schedule for concurrent occupancy so private and shared claims cannot oversell the same space.
6. Confirm a test: book one shared seat, then attempt a private claim on the same window—or the reverse—and verify inventory blocks instead of double-selling.

Related questions

Is private the same as a buyout?

No. Private is a session type with its own exclusive window on the room. Buyout locks the space so no other sessions run concurrently on that inventory. Both remove shared drop-in for the locked window; neither is a second room.

What happens if shared seats already sold when someone wants private hire?

You cannot convert a slot that already holds live shared bookings into an exclusive buyout without moving those guests first. Sell private only on windows that still have clear exclusive inventory, or move shared guests before locking the space.

Do sauna and cold plunge share one conflict pool?

Only if you attach them to one space or shared resource. Normally each space has its own seats and concurrent seat pool, so a private sauna hire does not auto-block plunge seats.
