How much does it cost to open a day spa?

A day spa typically costs $100,000 to $350,000 to open, with the wide range driven by location, number of treatment rooms, and level of build-out. A small 2-3 room spa in a suburban strip mall can open for $80,000-$120,000, while a luxury urban spa with wet rooms and saunas can exceed $300,000.

How many treatment rooms does a new spa need?

Most new spas start with 3-5 treatment rooms to balance capacity with overhead costs. Each room costs $5,000-$15,000 to equip and build out. You want enough rooms to keep therapists busy during peak hours without paying for unused space during slow periods.

Is owning a spa profitable?

Spas can be profitable with net margins of 10-18% once established. The average day spa generates $300,000-$800,000 in annual revenue. Profitability depends heavily on keeping therapist utilization above 60% and selling retail products, which carry 40-50% margins.
