EventPlanning

The chart below was designed to inform you of the sanitary guidelines you should apply to your event. Note that more restrooms than specified may be needed, if you want to prevent people from waiting in lines. Based on the anticipated male/female ratio at the event, you may need to 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.

We provide PURELL Hand Sanitizer Dispenser in each unit at no charge
