How many toilets for an event?

Short answer: for sports, concerts and festivals we recommend one toilet or one urinal space per 50–75 guests. Everyone comes at once, and the queue gets long if you only have the minimum. The minimum under the DSB guidance is one toilet per 100 women, and one toilet per 500 men plus one urinal per 150 men. Add at least one accessible toilet.

The table

Duration	Women	Men
Over 6 hours	1 toilet per 100	1 toilet per 500 + 1 urinal per 150
Under 6 hours	1 toilet per 120	1 toilet per 600 + 1 urinal per 175

The figures are minimums. Increase the number when a lot of alcohol is served, when people stay overnight on site, and when everyone needs the toilet at the same time, such as in the interval or before the last concert.

Municipalities use the same guidance. Stavanger municipality states that events with alcohol need more toilets than others, and that the municipality can require the organiser to provide enough toilets.

Many rental companies work on one toilet per 50–75 guests. That is more than the minimum, but keeps queues short even when everyone needs the toilet at once.

An example

A concert with 1,000 guests, half of them women, longer than 6 hours. We then recommend:

• 9 toilets
• 5 urinal spaces
• 1 accessible toilet

DSB's minimum is 6 toilets and 4 urinal spaces. If alcohol is served, or people stay overnight on site, you should have even more. The calculator above works it out.

That can be covered with one toilet trailer with 8 WCs and 4 urinals and one accessible toilet, or with festival cabins and a four-person urinal.

Toilet trailer or cabins?

• Toilet trailer, with 8 WCs and 4 urinals or 10 WCs and 3 urinals, with a sink in every cubicle. It needs power, but not water or drainage. It has frost protection and can be used in winter. It suits events where you want something close to a normal toilet: weddings, concerts and longer events.
• Festival cabins are light and can be placed where you need them, in several groups. They suit large audience areas and races.
• A urinal for four at once clears the queue on the men's side.

Placement

• Place the toilets no more than 20 metres from a road the emptying truck can drive on.
• Ideally keep them at least 50 metres from food stalls.
• Level ground, secured so they don't tip over, and ramps that aren't slippery.
• On large sites: spread them over several locations instead of one long row.

Does it run over several days?

A one-day event can usually manage without emptying during the event. If it lasts longer, the toilets must be emptied, preferably in the morning. Tell us how long you need them when you order, and we'll arrange the emptying straight away.

For the Birkebeinerrennet ski race we supply more than 110 festival toilets, as well as urinals and toilet trailers. We know what it takes, even when it gets big.
