What does a restroom trailer cost by size?
Stall count does most of the work. A 2 stall restroom trailer sits at the bottom of the range and suits a small wedding or an office site. A 4 stall trailer is the common middle choice for a crowd of a few hundred. An 8 stall trailer covers a large event and prices near the top. A luxury restroom trailer adds finish, climate control and vanity space rather than raw capacity, so it can cost more than a larger plain unit. A shower trailer prices separately again. The full fleet bands are on the porta potty rental cost page.
Why is a trailer so much more than a porta potty?
Because it is a different machine. A standard porta potty rental is a moulded cabin with a 60 to 70 gallon holding tank, delivered by one driver and set on any firm level spot. A trailer is a towed vehicle with flushing bowls, sinks, lighting, a fresh water tank and a waste tank, and it needs a level pad, an approach a truck can tow into, and usually a power connection. The restroom trailer rental page covers what the unit actually includes. That equipment, the towing, the levelling and the pump out at the end are what the extra cost pays for.
What moves the price up or down?
Duration first: a weekend hire pays a premium, while a monthly hold spreads the delivery and towing across weeks the way a monthly porta potty rental does. Then access, because a trailer that has to be reversed 300 feet down a narrow lane takes a driver far longer than one dropped beside a road. Then services: a unit with a mains water connection and shore power costs less to run than one relying on tanks and a generator, and sites without supply often add a temporary power pole. Distance matters as always, so Cedar Hills at 2.3 miles north prices below Lake Oswego at 9.3 miles southeast. Guest count and service frequency finish the picture.
When is a trailer worth it over cabins?
When the audience will not accept a plastic cabin, or when the count gets high enough that a bank of them looks worse than one trailer. A wedding is the clearest case, and a film set or a corporate day are close behind. A festival or a concert usually mixes both: trailers front of house, cabins back of house. For construction, cabins almost always win on cost, and the count is set by OSHA 1926.51(c), which requires one facility for up to 20 workers and one seat and one urinal per 40 above that. The how many porta potties do I need guide walks that math before you price anything.
What is included in a quote?
The trailer, the delivery and setup, the service schedule, and the collection. Ask about all four. Setup on a trailer is real work rather than a drop, since the unit has to be levelled and connected. Service means pumping the waste tank and restocking, and the ANSI/PSAI Z4.3 baseline of one visit a week for up to 10 users across a 40 hour week is the anchor we start from before adjusting for real traffic. If the event serves food, add a handwashing station or a portable sink, because 29 CFR 1910.141(d)(2) requires soap and towels or a dryer where washing facilities are called for.
Does an accessible unit cost more?
Yes, and for the same reason as an ADA accessible porta potty. ADA Standards 213.2 requires at least 5 percent of clustered units, and never fewer than one, to be accessible. An accessible stall needs a 60 inch turning circle under ADA 304.3.1 and a 32 inch clear door under ADA 404.2.3, which means a larger shell, a ramp and often a lift. Trailers can be specified with an accessible stall built in, and on a public event that is usually the right call. The ADA restroom requirements page has the detail.
How do you keep the cost down?
Book early, because peak Beaverton weekends price at a premium and a rushed slot costs more. Right size the unit rather than buying headroom you will not use. Put everything on one delivery run: a trailer, a dumpster and temporary fence arriving together beat three separate mobilisations. Give the driver a clean approach and a level pad so setup is quick. And ask for the service interval in writing, since that line is where a cheap looking quote usually hides. Send a quote request with your date, guest count and site details.
What is the cheapest restroom trailer option?
A 2 stall trailer on a weekday, close in, with mains water and power available. Strip any of those conditions and the number climbs.
Do trailers need power on site?
Most do for lighting, water pumps and climate control. A shore power connection is cheapest, a generator works where there is none, and a temporary power pole is the usual answer on a build.
How much space does a trailer need?
A level pad the length of the unit plus a towing approach, and clear space at the service side for the pump out. Walk the spot with us before the date. The placement guide covers the same questions for the rest of the fleet.
Can I hire one for a single day in Beaverton?
Yes, and the daily band starts near 175 dollars for the smallest unit. Delivery and setup are still full cost on a one day hire, which is why weekend and weekly rates often look better per day. Check the per day page and the service areas list, then call.
