How Do I Calculate How Many Toilets I Need for my Event?

Are you gearing up to host a large event, such as a festival, expo, school fete, or something equally exciting? One crucial detail you don't want to overlook is the provision of portable toilets. Neglecting this aspect can lead to catastrophic results. In fact, for most large events, providing access to toilets is not just a courteous gesture but a legal requirement. Ensuring access to proper sanitation not only enhances the guest experience but also ensures compliance with regulations.

But how many toilets do you actually need for your event? Is there a magic formula to calculate this? Surprisingly, the answer is yes, sort of.

Calculating Your Toilet Needs

It's often recommended that for every 50 people in attendance, you should provide 1 portable toilet. For example, for an event with 100 guests, you'd require approximately 2-3 portable toilets. However, several factors come into play when determining the precise number of toilets needed for your event.

Event Duration

The length of your event directly affects the toilet requirements. Longer events mean more frequent toilet usage. On average, individuals need to use the toilet every 3 to 4 hours. Therefore, a multi-day festival will necessitate more toilets than a single-day event to minimise queues and maintain the flow of your event.

Alcohol Consumption

Alcohol consumption is another factor to consider. Alcohol acts as a diuretic, increasing the frequency of toilet visits. If your event includes alcohol service, such as weddings, wine expos, or festivals, you may need more toilets than the standard 1-per-6--people ratio. We recommend adding a 15%-20% allowance for alcoholic events. 

Demographics

Demographics also play a significant role. Seniors and parents with babies require more frequent toilet trips, as do women (who often face longer queues). Consider the composition of your attendees when determining the required number of toilets. For instance, events targeting specific demographics, such as women's health expos, may necessitate additional toilets.

Choosing the right number of toilets is crucial for the success of your event. It's better to err on the side of caution.
