Frequently Asked Questions

What is a good treatment room utilization rate for a day spa?

A healthy day spa room utilization rate is 60–78%. Below 60% usually means idle capacity and lost revenue; consistently above 78% may signal you need more rooms or therapists to meet demand.

How do I improve day spa treatment room utilization?

Improve room utilization with online booking, waitlists for cancellations, combination treatment scheduling, and membership plans that lock in recurring visits. Each recovered idle hour adds directly to revenue.
