Calculating the number of toilets required for an event can be a particular
challenge. Where local laws or regulations do not exist, FEMA says the
following guidelines can be applied. Better management of events can be
achieved by providing additional facilities.
Assume a 50/50 male/female split unless otherwise advised. The following
tables should be used only as a guide.
At events where the duration extends overnight or longer, provide hygienic
washing facilities. Suggested minimum requirements for facilities at
campgrounds, based on two to three nights' camping, are as follows:
Males Females
Patrons Toilets Urinals Sinks Toilets Sinks
<500 1 2 2 6 2
<1,000 2 4 4 9 4
<2,000 4 8 6 12 6
<3,000 6 15 10 18 10
<5,000 8 25 17 30 17

More than 8 hours 100%
6–8 hours 80%

Less than 4 hours 70%
DURATION OF EVENTS QUANTITY REQUIRED
These figures may be reduced for shorter-duration events as follows:
SEX TOILETS URINALS SINKS SHOWER
M 1 per 50 1 per 100 1 per 75 1 per 100
F 1 per 25 N/A 1 per 75 1 per 100
