How Many Restrooms Do I Need? | Operation Guidelines


It is important to know how many restrooms do I need for an event. This amount is determined by counting the number for stations.  Further, a station is defined as a toilet or urinal that can be used individually.  For example, if a restroom trailer has three urinals and four stalls then the trailer is a seven station.  But, if the trailer has a urinal and a toilet in a private room then this is only classified at one station.  Since, this private room could only be used individually by one person at a time. 

To understand how to use the chart, lets begin with some guidelines.  Consequently, under normal conditions most people will use the restroom trailer once every 4 hours. After that, weather conditions, consumption of food, beverages and liquor will increase the usage. Finally, below is a table to use as a guide for how many stations you may need. Of course, the chart is based on the size of the event and how long the event will last.
