How Do I Calculate How Many Toilets I Will Need For My Next Event?

Throwing a large event like a festival, expo, school fete or something else? Don’t forget to hire portable toilets! The results of doing so are catastrophic. In most cases, it’s a legal requirement for large events to provide access to toilets, so you’re not only doing all your guests a massive favour, but you’re sticking to the rules too.

The decision of hiring toilets for your next event is a no-brainer: obviously, the answer is ‘yes’. But how many toilets do you need? Is there some kind of magical toilet calculator which works out the math for you? Surprisingly, the answer is (sort of) also ‘yes’.

Calculating how many toilets you need

It’s often said that for every 60 people, you need 1 portable toilet. For 100 guests, you’d need roughly 2-3 portable toilets. For 200 guests, you’d need 6-7 portable toilets. But there are other factors which you need to consider when calculating how many toilets you need for an event.

Length of the event

The longer the event runs for, the more toilets you’ll need. This is because people are spending more time at your event and therefore will need to use the toilet more often. The average person uses the toilet every 3 to 4 hours, so you can see that toilet use will be far more frequent for a 3-day festival than one that goes for a day. The more toilets you have, the less queues there are and the better your event will flow.


We all know that alcohol is a diuretic substance, making us go to the toilet more often when we consume it. Therefore, if alcohol is being served at your event such as a wedding, wine expo or festival, you’ll need more toilets than the 1-per-60-people ratio. Speak with the experts at SBS Fence and Toilet Hire to calculate a suitable number of toilets for your next event.


Demographics should also be considered when calculating your number of toilets. Seniors require more frequent toilet trips, as do parents with babies. A higher number of female attendees could also impact your decision on how many toilets you need as there’s often a longer queue for female toilets. If your event is something like a women’s health expo, then you should consider an increased number of toilets.

The right number of toilets is a make-or-break decision that influences the success of your event – so, at the end of the day, it’s better to be safe than sorry.
