Restroom trailer rental cost calculator

Work out what renting a restroom trailer will really cost. Start from the rate you are quoted for the unit size, then add the lines that arrive with it: delivery and setup, the servicing that pumps and restocks it, a generator if the site has no power, a water supply if there is no hookup, and an attendant if you want one. See the total, a realistic range, and what each part adds.

§ 01 Your numbers

Change anything. The answer updates as you type.

The company's price for the unit size and rental period you pick. A two-station trailer for a day sits at the low end; a large or luxury unit for a weekend runs well above it.
The truck to drop the trailer, level it, connect it, then return to haul it away. Longer drives, tight access and an off-road or unlevel spot all push this up.
A booking longer than a day, or a high-traffic event, needs the waste tanks pumped and the trailer restocked between uses. Count the visits beyond the first; leave at zero for a single day with one drop-off.
What the company charges to pump the holding tanks and restock each visit. Set by the company and how far the service truck drives.
The trailer runs lights, a water pump and climate control, so it needs power. Zero if the site has a suitable supply the trailer can plug into; otherwise this is a generator and its fuel.
The trailer needs fresh water for the sinks and the flush. Zero if there is a hookup on site; otherwise the company fills the onboard tank or hauls water, which is a line of its own.
A larger or formal event often books an attendant to keep the trailer stocked and clean through the night. Priced by the hours; zero if you skip it.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

A RESTROOM TRAILER IS PRICED BY THE UNIT, AND THE RATE IS YOURS.
Rental companies quote by the size of the trailer, meaning how many stations it has, at a rate that turns on the length of the booking, the season and how far the truck drives. That rate reaches you as a quote, so it is your input here, and every default on this page is ours and editable. The calculator does not guess the rate; it adds up the one you were given, plus the lines that come with it

The trailer rate is one line, and the lines beside it can rival it. Delivery and setup, the servicing that pumps the tanks and restocks the unit, a generator if the site has no power, and a water supply if there is no hookup are separate charges. A quote that covers the trailer alone will understate what you pay for the day.

A restroom trailer brings no power and no water with it. It runs lights, a water pump and heating or air conditioning, so a site with a suitable supply saves you the generator line, and a site with a water hookup saves you the water line. A remote spot with neither means renting both, which is real money on top of the trailer.

Servicing scales with how long you keep it and how hard it is used. A single-day event with one drop-off may need no return visit, while a weekend or a busy crowd needs the holding tanks pumped and the unit restocked between uses. Set the visit count to match your booking, because each visit is a truck and a fee.

This is the trailer and its own kit. Tables, tents, catering equipment, hand-wash stations beyond the trailer's own sinks, and any permit your venue requires are separate, and they are not in this total.

Frequently asked questions

How much does it cost to rent a restroom trailer?
Start from the rate the company quotes for the unit size, then add delivery and setup, the servicing that pumps and restocks it, a generator if the site has no power, a water supply if there is no hookup, and an attendant if you want one. The calculator above builds the real number from your quote, because the rate turns on the number of stations, the length of the booking, the season and travel distance rather than on any published figure.
Why is the delivery charge separate from the rental?
Because it is a truck and a crew, twice. They drive out, drop the trailer, level it and connect it, then come back at the end to haul it away. A longer drive, a tight or off-road access point, and an unlevel spot that needs blocking all add to that line, which is why it is quoted apart from the trailer rate itself.
Do I need a generator and a water supply?
It depends on the site. The trailer runs lights, a water pump and climate control, so it needs power, and it needs fresh water for the sinks and the flush. A venue with a suitable electrical supply and a water hookup lets the trailer plug in and saves you both lines. A remote spot, a field or a bare lot usually means renting a generator and having water hauled or the onboard tank filled.
How often does a restroom trailer need servicing?
It scales with the length of the booking and the traffic. A single-day event with one delivery may need no return visit at all, while a multi-day rental or a high-traffic crowd needs the waste tanks pumped and the unit restocked between uses. Each visit is a service truck and a fee, so set the visit count in the calculator to match how long and how hard the trailer will be used.

A tow-behind trailer is inexpensive by the day in town, since you tow it with your own vehicle and pay by the rental, not the mile. A one-way rental, damage coverage, and a hitch are what move the total.
