How Many Restroom Trailers Do I Need?

Each trailer's guest count is its maximum: one bathroom (a private room or a urinal) for every 50 guests. That is why the 2-Stall is rated for up to 100 guests, the 5-Stall for up to 250 and the 10-Stall for up to 500.

At the maximum, expect a short line at the busiest moments. For comfort with no lines, we recommend 1 bathroom for every 25 guests, which means choosing a trailer rated for about twice your guest count.

The mix of guests matters too. Women's rooms see longer visits than urinals, so for a wedding or a gala we lean toward trailers with more private rooms. For festivals and sporting events with a mixed crowd, urinals keep the lines moving.

Finally, think about placement. One large trailer in the right spot is often better than two small ones, but at a big site with a long walk, two trailers at either end can be the better plan. Tell us about your venue and we will help you decide.
