Stone Industries Event Planning Help

The chart below was designed to inform you of the sanitary guidelines you should apply to your event. Note that more restrooms may be needed than specified if you want to prevent people from waiting in lines. Based on the anticipated male/female ratio at the event, you may order additional units. Studies have shown that women take, on average, 40% longer than men to use restroom facilities. If you are serving food and/or beverages (especially liquors), you might also consider ordering additional restrooms.

How to use the planning chart:

1. Determine how long your event will last.
2. Determine approximately how many people will attend your event.
3. Use the chart below to calculate the number of units needed to insure sanitary conditions.
