Public Events
How many portable toilets are required for an event?
The number of portable toilets required for a public event depends on several key factors:
1. Event Duration
- The longer your event, the more toilets will be needed to accommodate attendees.
2. Food and Drinks
- If food and beverages are served, expect a higher frequency of use. We recommend increasing the number of toilets by at least 30% to account for this.
3. Female Attendees
- If more than 50% of your guests are female, the number of toilets should be increased.
4. Accessible Toilets
- Always provide accessible toilets in addition to the standard number of units.
5. Cleaning Intervals
- Regular cleaning is essential for longer events:
- Events over 6 hours: Toilets should be cleaned every 6 hours.
- Events up to 12 hours: Toilets should be cleaned every 12 hours.
- For larger events, consider our on-site cleaning service to maintain hygiene standards.
