How many restroom trailers do I need for 200 guests?
A planning guide with the numbers, and a calculator to size your own event.
The short answer for 200 guests
Event planners commonly plan around one toilet for every 50 guests for events of up to about four hours. For 200 guests that is 4 stalls, so one 6-stall combination trailer covers it with room to spare.
Plan for more stalls when the event runs longer, when alcohol is served, or when most guests arrive and leave at the same time.
Quick reference
- Up to 50 guests: 1 stall (13 ft, 3-stall trailer)
- 100 guests: 2 to 3 stalls (13 ft, 3-stall trailer)
- 200 guests: 4 to 6 stalls (22 ft, 6-stall trailer)
- 300 guests: 6 to 8 stalls (30 ft, 8-stall trailer)
- 500 guests or more: 10 or more stalls, using two trailers
Add an ADA stall
If the event is public, include a combination trailer with a dedicated ADA stall. Ask for the 3+1 or 8+1 layout.
