To open a private gym rented by the hour you need six things: a room with a door you can control remotely, equipment that survives daily use by strangers, a slot grid with prices, a booking system that sends each customer a door code valid only for their slot, house rules, and insurance that knows nobody is on site. Customers book a slot, pay online and get the code by SMS. No keys, no staff. Plan about a month from decision to first paid booking.
What a private hourly gym is
A private gym (also called a self-service gym, hourly gym or private gym hire) sells exclusive use of the whole room for a fixed slot, usually 60 minutes. The customer who books 18:00–19:00 has the gym to themselves or shares it with the people they brought. No memberships, no classes, no strangers on the next machine.
| Private hourly gym | 24/7 membership gym | |
|---|---|---|
| Who is inside | One booking at a time | Any customer, any time |
| Access | A code per booking, valid for the slot | A card or app key valid for months |
| Revenue unit | Booked hours | Customers per month |
With one booking inside at a time, the booking record tells you who was there and when. Typical customers are personal trainers with a client, couples, small groups and people who avoid crowded gyms.
Step 1: Find and fit out the space
Size the room from the equipment and its clearances, not from a square-metre figure. Check ceiling height, floor load, ventilation, and what the lease says about noise and opening hours. Look at the door before you sign: it decides which access setup fits. Buy commercial-grade equipment. The checklist is in small private gym: space and equipment.
Step 2: Set slots, buffer and opening hours
60-minute slots are the usual default; a customer who wants longer books two in one order and gets one code. A 1-minute buffer is enough to keep two door codes apart: a gym open 6:00–22:00 fits 15 slots a day instead of 13 with a 15-minute buffer. Cleaning goes into a daily block, not the buffer. See slot length, buffer and cleaning time and try your hours in the slot and revenue calculator.
Step 3: Set prices
Divide your fixed costs per available hour by a realistic occupancy and price above that. Charge more on weekday evenings and weekends, less in quiet hours, and use discount codes for launches. The method is in how much to charge per hour.
Step 4: Door access without keys
A key means a handover, and a shared code lets every past customer in. You want a code per booking, valid only during the slot.
We recommend a 2N keypad with a maglock, fitted by a professional door or access installer. It is the reliable choice for a gym that runs unattended every day. The simpler, cheaper alternative is a Nuki smart lock with a keypad on an existing cylinder, but customers can tamper with it. Other locks with time-limited PIN codes: ask us. Compare them in choosing door access, with details on 2N keypad + maglock and Nuki.
Step 5: Booking, payment and the code
Sending codes by hand works for a few bookings a week, not 15 changeovers a day; see how to choose a gym booking system.
With Sparekey a customer picks a slot, pays through Stripe (cards, Apple Pay and Google Pay) and gets an SMS with a time-limited PIN right after booking. If the internet at the door is down and a new code can’t be stored, the customer gets the location’s backup code. Customers can move their own booking up to 24 hours ahead. You get statistics, an invoice for each booking and a CSV export for your accountant. Chrám pohybu and Fithub run this way.
Step 6: Rules, camera and insurance
With nobody on site, the rules do the explaining: in the booking terms, on a poster by the door and in the confirmation e-mail. Start from the rules template. A camera is a decision, not a default; one on the entrance is far easier to justify than one over the training floor (camera in an unstaffed gym). Tell your insurer the gym is unstaffed, because standard policies may exclude it (insurance and liability).
Step 7: The month before launch
Payment gateway approval and booking an installer take days to weeks, so start them first. Door installation, prices, rules and photos run in parallel. In the last week, make a real paid booking and check that the code opens the door during the slot and not after it. What we need from you and when is in implementation.
What it costs
The categories are the same everywhere: room and fit-out, equipment, door hardware and installation, booking software, insurance, and running costs (rent, energy, cleaning, payment and SMS fees). Irish specifics are in opening a private gym in Ireland.
Sparekey costs €990 one-off plus €19 a month for Operations (hosting and maintenance). SMS are billed per message. Locations are unlimited. See pricing.
After launch
Unstaffed doesn’t mean no work: cleaning in the blocked window, a phone you answer and the rare incident, each with a routine in what can go wrong without staff. Track occupancy and revenue per available hour in your statistics; both are explained next to the calculator.
