Direct answer
Size cryotherapy around paid demand and the rest of the member visit, not around the chamber's brochure capacity. A chamber can be the high-ticket anchor while smaller localized equipment handles more people at once. Work out peak flow, room turnover and staffing before you work out payback.
Start with the customer journey
Follow one member from arrival to departure and time each stage - preparation, session, cleaning, recovery and moving between rooms - for every modality. The slowest shared resource usually sets the real capacity of the studio.
Typical bottlenecks: one staff member covering several rooms, a single changing area, cleaning that runs late, limited electrical capacity, nitrogen deliveries, gaps in the booking schedule and equipment downtime.
Whole-body versus localized roles
A whole-body chamber usually works as a destination service in its own right; compare its room and utility needs, realistic session flow, operator requirements and local support. Localized equipment handles targeted sessions and can take less space, although its cooling source still drives supplies and room planning.
Give each piece of equipment a job.
- Acquisition service - attracts a new visit
- Membership service - used repeatedly within a plan
- Add-on service - increases value of an existing visit
- Capacity service - handles waiting or peak flow
The job decides which demand and pricing assumptions belong in the model.

Work out the bottleneck with the same hour
A planning example: a shared resource available for 60 minutes and occupied for 8 minutes per completed appointment can handle at most seven whole appointments an hour, before booking gaps or disruptions. If another resource every client needs can only manage six in that hour, the studio completes six - however high the chamber's advertised maximum.
Replace these illustrative numbers with timings from a trained team running the exact service. Note which tasks truly overlap, which need the same staff member and which happen outside the equipment cycle. This is scheduling arithmetic, not a treatment protocol or a demand forecast. In the business plan, keep unpaid demonstrations and membership redemptions separate from completed paid sessions.
Staged equipment plan
Stage 1 - Minimum viable service mix
Open with the smallest mix that can prove people will pay, without relying on full theoretical capacity. Keep working capital for the launch, staff and local marketing.
Stage 2 - Remove the measured bottleneck
Add capacity only when booking data shows where customers wait or where the schedule loses sales. The next purchase might be a cheaper parallel modality rather than a second chamber.
Stage 3 - Add redundancy or premium capacity
Weigh service continuity, preventive maintenance and the cost of your flagship service being closed. Redundancy can be worth buying for availability alone, even when average utilization is below capacity.
Financial inputs to collect
- Equipment and installed cost by modality
- Opening working capital
- Monthly finance payments
- Paid session price after discounts
- Membership allocation by modality
- Month-by-month session ramp
- Staff time by service
- Utilities and gas
- Consumables
- Maintenance reserve
- Downtime assumption
- Rent allocation by occupied square foot
- Marketing acquisition cost supplied by the operator
Online payback calculators can show very short payback periods because they assume high capacity or full utilization from day one. Keep technical capacity, expected utilization and paid demand as three separate numbers.
Supplier questions
- Documented behavior for consecutive sessions
- Precooling and recovery time between sessions
- Cleaning steps and time
- Scheduled service and support response
- Booking, usage-record or remote-diagnostics software
- Required software subscriptions and their cost
Decision rule
Choose the mix that still works in a conservative demand scenario and can handle the peak flow you've actually observed. A plan that needs full utilization from the first month has no room for error.
