Event toilet guide

How Many Portaloos Do I Need for an Event?

As a rule of thumb, hire one portable toilet per 50 guests for an event of up to four hours without alcohol, and one per 35 to 40 guests if it runs longer or there’s a bar. Add at least one accessible toilet, and a urinal unit for every 300 or so guests once the bar opens.

How many portaloos for 100, 200, 500 or 1,000 people?

Go by the number of people on site at the busiest time, not total tickets sold. Most organisers get it wrong by guessing low, and the queues show it.

Does alcohol change how many toilets you need?

Yes, more than anything else. In our experience, a bar increases toilet use by around 30 to 40%, and people visit more often as the night goes on. That’s why the guide drops from one toilet per 50 guests to one per 35 to 40 once drinks are served or the event runs past four hours.

Be honest with us about the bar when you book. Weddings and festivals with a busy bar need extra capacity, or tanks can fill before the end. For festivals, we plan for the busiest moment, not the average.

  • No alcohol, up to 4 hours. One toilet per 50 guests.
  • A bar, or longer than 4 hours. One toilet per 35 to 40 guests.
  • Free bar or a late finish. Add more, or go a trailer size up.
  • Several days. Plan servicing visits, and showers if people camp.

Accessible toilets, urinals and servicing

Accessible toilets

£135 plus delivery

Have at least one at any public event, and about one for every ten standard toilets at bigger events. Place them on firm, level ground near the main block.

Disabled toilet hire

Urinal units

From £150

A multi-bay urinal unit for every 300 or so guests takes pressure off the cubicles once the bar opens, and costs less than extra portaloos.

Event toilet hire

Servicing

Built into your quote

Events with more than 50 portaloos, or that run longer than a weekend, need servicing during the hire. We plan it into the quote so there are no surprises.

Luxury trailers

From £750 delivered

One trailer covers 50 to 250+ guests depending on size, with flushing toilets and running water. Prices vary by location.

Trailer vs portaloo

Toilets for running events

Runners need toilets most before the start, so that’s where the queues build. As a general rule, allow one toilet per 30 to 50 participants at the start area.

For a 5k or 10k, toilets at the start and finish are usually enough. For marathons, ultra marathons and trail runs, put two portaloos at every water stop, roughly every 10km, and add accessible toilets for spectators and runners who need them.

Send us your course map and we’ll suggest where the units should go. We’ve supplied more than 50 toilets for the Thames Path Ultra Challenge and toilets for two marathon events in East Sussex.

What we need for a race

  • The course map, with water stops and the start and finish
  • Expected runners, spectators and volunteers
  • Start time and road closure times
  • Vehicle access to each toilet point
  • Whether you need accessible toilets along the route
