When you’re organising an outdoor event, getting the toilet provision right is one of those details that can make a huge difference to the experience of your guests.

Too few toilets can lead to long queues, unhappy visitors and facilities becoming overused. Too many may mean spending more of your event budget than necessary.

So, how many toilets do you actually need for an outdoor event?

There isn’t one simple answer. The right number will depend on the size and type of event, how long it lasts, whether food and alcohol are being served, what facilities already exist at the venue and several other practical considerations.

Here are some of the main factors to think about.

1. How Many Guests Are Attending?

Your expected attendance is the obvious starting point.

A small private event with 100 guests will have very different requirements from a festival, sporting event or public gathering attracting several thousand people.

It is also important to consider whether everyone will be on site at the same time. Some events have a relatively constant audience, while others have people arriving and leaving throughout the day.

When planning toilet provision, it is usually sensible to work from your expected peak attendance, rather than simply the total number of tickets or visitors expected throughout the event.

2. How Long Will the Event Last?

Event duration has a major impact on toilet usage.

Facilities for an event lasting two or three hours may be used relatively lightly, whereas toilets at an all-day event, weekend festival or multi-day show will experience significantly more use.

For longer events, the question isn't simply how many toilets you need. You also need to consider cleaning, waste capacity, consumables and servicing during the event.

3. Will Food and Drink Be Available?

If people are eating and drinking at your event, they are naturally more likely to use the toilets.

Events featuring catering areas, food stalls, cafés and refreshments may therefore require greater toilet provision than shorter events where little or no food and drink is available.

You should also consider facilities for catering teams, event staff, contractors and other people working on site, not just your paying guests.

4. Will Alcohol Be Served?

Alcohol can significantly increase the frequency with which people need to use toilet facilities.

If your event has a licensed bar, beer tent or other alcohol provision, you should take this into account when deciding how many toilets to hire.

This can be particularly important during peak periods. Nobody wants to spend a large part of their evening queuing for a toilet because provision was based purely on the number of people attending.

5. Are There Existing Toilets at the Venue?

Portable toilets don't necessarily have to provide 100% of your event's requirements.

If the venue already has permanent toilet facilities, these can be factored into your planning. However, consider their location, capacity and accessibility, as well as whether they will actually be available to event visitors.

For larger outdoor sites, additional portable facilities can also help distribute toilets more effectively, reducing queues and preventing visitors having to walk long distances across the venue.

6. Don't Forget Accessible Toilet Provision

Accessibility should form part of your planning from the outset.

Providing suitable accessible toilets helps ensure that people with disabilities and additional mobility requirements can use your event comfortably and with dignity.

The toilets also need to be positioned appropriately. An accessible toilet isn't particularly accessible if reaching it requires travelling over unsuitable ground or navigating unnecessary obstacles.

Think about the entire route to the facility, including surfaces, gradients and proximity to the main event areas.

7. Think About Your Location

Where your event takes place can influence both the type and number of toilets required.

A compact town-centre event is very different from a festival spread across a large field, agricultural showground or remote outdoor venue.

On larger sites, toilets may need to be positioned at several strategic locations rather than concentrated in one area.

You should also consider access for delivery and collection vehicles and, where servicing is required, whether service vehicles can safely reach the facilities during the event.

8. Will Your Toilets Need Servicing?

For longer and multi-day events, servicing becomes an important part of the planning process.

Depending on the type of facilities, visitor numbers and duration of the event, toilets may require waste removal, cleaning and replenishment of consumables.

Planning servicing in advance helps facilities remain clean, usable and pleasant throughout the event rather than simply providing enough toilets at the start and hoping for the best.

What Type of Event Toilets Should You Choose?

Numbers are only part of the equation. There are also different types of facilities available depending on your event and audience.

Traditional portable toilets provide a practical solution for everything from private gatherings to large outdoor events, while accessible toilets provide additional space and features for users with mobility requirements.

For organisers looking for a different approach, compost toilets can be particularly suitable for festivals, outdoor events and locations where organisers want to explore more environmentally conscious sanitation options.

For events requiring a higher level of comfort, toilet and shower trailers can provide an alternative to individual portable units.

The right solution may involve a combination of different facilities rather than relying on a single type of toilet across the entire site.

So, How Many Toilets Does Your Event Need?

There is no universal number that works for every event.

A proper recommendation should take into account:

Expected and peak visitor numbers

Event duration

Food and drink provision

Alcohol consumption

Existing facilities

Accessible toilet requirements

Size and layout of the venue

Event location and vehicle access

Servicing and cleaning requirements

Staff, contractors and other people working at the event

Planning these factors in advance means your toilet provision can be matched to how your event will actually operate.
