As a Commercial Officer planning a successful outdoor event, you need to organise more than just the entertainment and catering. Regardless of event – be it a festival, corporate event, sporting competition, wedding, agricultural show, or public gathering - getting your event toilet hire right can make a huge difference to guest satisfaction.
Getting it wrong can quickly lead to long queues, unhappy attendees, hygiene issues, and complaints, but hiring the correct number of portable toilets or luxury event toilets keeps your guests comfortable and helps your event run smoothly from start to finish. Read on to find out how!
Toilet planning for multi-day events
Toilet demand at single-day events is relatively straightforward to estimate. Multi-day events, however, are more complex because usage increases significantly over time. Guests stay on-site longer, food and drink consumption rises, and overnight attendees need access around the clock.
Generally accepted recommendations are:
• 1 toilet per 60–100 guests for events lasting under 6 hours
• Additional units for events serving alcohol
• Increased capacity for multi-day or overnight events
• Separate facilities for staff, traders, and VIP areas
For events lasting several days, such as camping festivals, each guest will use toilet facilities multiple times daily. This has the knock on effect of servicing and waste removal becoming as important as the units hired.
Using an event toilet calculator can help commercial officers estimate requirements more accurately based on attendance, event duration, catering, and alcohol consumption.
How to use an event toilet calculator
An event toilet calculator is one of the simplest ways to estimate how many portable toilets or toilet trailers you need. Most calculators use a combination of:
• Expected attendance numbers
• Event duration
• Male/female split
• Whether alcohol is served
• Whether food vendors are present
• Number of disabled attendees
• Overnight camping provision
Multi-day events – General guide for single use toilets
| Attendance | Recommended Portable Toilets |
| 100 guests | 2-3 units |
| 250 guests | 4-6 units |
| 500 guests | 8-10 units |
| 1000 guests | 15-20 units |
| 5000+ guests | Bespoke calculation required |
If alcohol is being served, toilet demand can increase by up to 30–40%, particularly at festivals and evening events.
How many luxury toilet trailers do you need?
As luxury toilet trailers contain multiple cubicles and urinals within one unit, fewer trailers are needed compared to standard portable toilets.
Multi-day events – General guide for luxury toilet trailers
| Attendance | Luxury Toilet Unit |
| 100-150 guests | Small luxury trailer - Luxury 2 + 1 Toilet Unit |
| 200-300 guests | Medium trailer - Luxury 3 + 1 Toilet Unit |
| 400+ guests | Large trailer - Luxury 4 + 2 Toilet Unit |
For multi-day events, it is important to account for cleaning and servicing intervals. High-end facilities can quickly lose their premium feel without regular maintenance.
Many commercial event organisers now combine standard event toilet hire for general admission areas with luxury event toilet hire for VIPs and hospitality, plus accessible toilet units for inclusivity compliance. This mixed approach helps balance budget, guest experience, and operational efficiency.
Choosing the best location for event toilets
Almost as important as how many toilets you hire, is where you place them at your event venue. Poor positioning can create congestion, hygiene problems, or accessibility issues. At JB Event Facilities, we will help assess your site layout before delivery.
Key considerations for portable toilet placement
Wherever portable toilet units are positioned, they should:
• Provide easy access for guests
• Be clearly visible
• Be easy to reach
• Be spread evenly around the venue
• Be located near food and drink areas without being directly beside them
• Never be that far that guests have to walk excessive distances, especially at large venues
Delivery vehicle access
At JB Event Facilities, we need to ensure sufficient access for our delivery vehicles. To help us provide the best service to our clients, we need to be made aware as early as possible of:
• Gate widths where applicable
• Ground conditions
• Turning space
• Weight restrictions
• Overhead obstructions
• Wet fields, steep gradients, and narrow tracks, as these can create major installation delays
Signpost toilets clearly around the venue
To prevent event guests and attendees from becoming frustrated, particularly at a large venue, organisers should ensure toilet facilities can be located quickly. Clear signage will help with this by:
• Reducing queues
• Improving crowd flow
• Preventing guests entering restricted areas
• Improving overall attendee experience
For large events, consider:
• Illuminated signs for evening use
• Site maps
• Directional arrows
• Separate signage for accessible toilets and luxury facilities
Good signage is especially important at multi-day events where attendees may be unfamiliar with the site layout.
Book in advance to avoid disappointment
There are peak seasons in the portable toilet hire industry and demand rises sharply during:
• Summer festival season
• Wedding season
• Bank holiday weekends
• Major sporting events
Leaving bookings too late can limit availability, particularly for luxury event toilet trailers, so commercial officers should ideally arrange toilet hire:
• 3–6 months ahead for large events
• Earlier for peak-season dates
• Immediately after confirming venue and attendance estimates
Early booking also gives us time to:
• Conduct site visits
• Recommend servicing schedules
• Plan delivery logistics
• Provide accurate event toilet calculator estimates
Cleaning and servicing for multi-day events
Depending on guest numbers, we offer:
• Daily cleaning
• Waste tank emptying
• Restocking consumables
• Water refilling
• Emergency call-out support
Without proper servicing, large numbers of toilets can become unusable surprisingly quickly, but we will create an individual servicing plan that is tailored to:
• Attendance
• Event duration
• Weather conditions
• Usage patterns
