How Many Portaloos Do You Need?
A practical starting point for estimating portable toilets, accessible units and handwash stations.
Start with people and duration
For a short event, a rough planning point is one standard toilet for about 50 people over four hours. Longer events, larger crews and limited amenities increase the requirement. Treat the number as a conversation starter, not a compliance calculation.
Adjust for the job
Alcohol service, queues, overnight use, food service and remote access can all change the mix. Construction sites may need regular servicing, while a wedding may prioritise presentation, handwashing and accessible access.
Ask for a supplier plan
Give the supplier the headcount, hours, site or venue access, dates and whether alcohol is served. Use the calculator on a city page, then ask the hire company to confirm the final number.
