Portable Toilet Calculator

Under normal conditions most people will use sanitation facilities once every four hours. Take into consideration that the consumption of food, liquids, beer, and other alcoholic beverages will increase usage by 30-40%.

Atlantic Potties recommends the following for large events:

1) Determine how many hours the event will last, if it is multiple days use the longest day.

2) Determine how many people will attend, if there are multiple days determine the peak day.

3) Use the chart to calculate the number of portable restrooms needed for adequate sanitation conditions.

Use these tables as a guide - then give us a call (757) 460-6100 or use our request estimate form.
