What does a restroom trailer need on site?

A restroom trailer needs a level spot the truck can back into, a standard garden hose connection, and a 110-volt outlet within about 100 feet. If the venue has no outlet, we bring a quiet generator; if there is no water, we add a holding tank. Trailers cannot go on steep slopes or soggy grass.

  • Space: the trailer plus room for steps on the door side.
  • Power: one dedicated 20-amp household circuit or a generator.
  • Water: a hose bib, or a fresh-water tank we provide.
  • Access: a path wide enough for the truck and trailer, with no low branches.
