I'm booking a restroom trailer for our outdoor fundraising gala next month. We expect 150 guests over five hours, serving dinner and wine. The site is a flat grassy area behind our community center, and a truck can pull right up to the edge of the grass. I've seen trailers with multiple flushing stalls, sinks, and lighting. Before I finalize the rental, I need to know exactly what the operator will need from us on delivery day. What are the absolute requirements for power, water, and ground preparation? Do most trailers come with their own generator and water tanks, or is that something we have to arrange separately? Also, how much truck access does the pump-out service need?

Owen and Jules covered the basics, but confirm with your rental company whether the trailer's onboard fresh water tank and generator are included or an extra rental. Some operators include them, others charge separately. For your 150-guest gala with dinner and wine, the trailer's holding tank will fill faster than usual, so schedule a mid-event pump-out. The driver will check that the grass is firm enough to support the trailer's weight and jacks without sinking, and that there are no underground sprinklers or utilities marked. Also, ask the operator if they require a signed site plan showing the trailer placement and truck access path before delivery.

A restroom trailer needs level ground, a power source, a water supply and clear truck access for delivery and pumping. The operator will need you to have the site ready: a flat, firm area of grass or dirt that is clear of overhead branches and debris. The trailer must be leveled on its built-in jacks. For power, a standard two-stall trailer typically requires a dedicated 20-amp circuit; larger trailers need more, often 50-amp service. You can provide this from a building outlet or rent a generator from the operator. For water, you can connect a standard garden hose to a building spigot, or the trailer can use its onboard fresh water tank, which the operator will fill on delivery and may top up during the event. The pump-out service needs the same truck access as delivery. The vacuum truck hose reaches about 25 feet, so the trailer must be placed within that range of where the truck can park on a solid surface.

  • Kim S. Owen's right about the 25-foot hose reach for the pump-out. In my experience, the vacuum truck also needs a solid surface like asphalt or compacted gravel to park on, not soft ground that it could sink into.

Owen's right, but check your local permit office. Many health departments require a restroom trailer to have a fresh water connection from an approved source, not just an onboard tank, for events serving food. The driver will verify the site is flat and stable enough for the jacks and that overhead clearance is at least 12 feet for delivery. For a five-hour event with dinner and wine, plan for a service visit during the event to empty the holding tanks and refill the fresh water supply. Confirm with your rental company if their pump truck needs a paved surface or can handle your grassy edge.

  • Kim S. Also, the fresh water connection rule is often tied to the food permit, not the toilet itself. If you're not serving food, the onboard tank might be acceptable.
