Restroom Trailer Water and Power Requirements: What Your Site Needs
Restroom trailers feel like an indoor bathroom because they run like one. Here is exactly what the site must supply.
What power does a restroom trailer need?
A restroom trailer needs a dedicated 110-volt, 20-amp outlet within 100 feet. "Dedicated" means nothing else draws from that circuit, because the water pump, lights and climate control cut out when a coffee urn or band amp shares it. A generator must supply steady 110V/20A, typically 3,500 watts or more.
What water does a restroom trailer need?
A restroom trailer needs a garden-hose spigot with steady pressure within reach of a standard hose run. The hose fills the trailer's fresh-water system and keeps sinks and flush toilets working. Without a spigot, we fill the onboard tank before delivery, which covers a short event.
How much space does a restroom trailer need?
A restroom trailer needs a level spot about 8 by 20 feet for a 2- or 3-stall model, plus room for the truck to back it in and pull away. Allow 4 feet clear in front of the doors for the steps and a small landing. Slopes over a few degrees need leveling blocks.
What if the venue is off-grid?
At an off-grid venue with no outlet or spigot, choose self-contained flushing cabins with sinks, or bring a quiet inverter generator rated for 110V/20A and confirm the trailer can run from its tank. Flushing cabins are the simpler choice for ranches and remote vineyards.
