A restroom trailer rental in St. Louis, MO runs from a 2 stall unit for a backyard wedding up to an 8 stall trailer for a festival crowd, with weekend rates starting around 900 dollars, and pairs well with a porta john rental or a portable restroom rental when you need overflow capacity. St. Louis Porta Pros builds every quote around headcount, hookups and how long you need the unit on site.
Cost depends on stall count, trip length and whether you want a luxury interior with finished walls. A weekday rental of a mobile restroom trailer runs from 175 dollars a day on the low end up to 2,500 dollars a day for a large or luxury unit, while weekend bookings for the same category of trailer land between 900 and 3,000 dollars. Weekly rentals stretch from 150 dollars for a basic setup to 1,650 dollars for something larger, and multi-day events like festivals often price as a flat event rate between 2,499 and 3,899 dollars. A 2 station restroom trailer rental cost sits at the lower end of that range because it needs less water, less waste capacity and a shorter setup. For a full breakdown by stall count and season, check restroom trailer rental cost or compare it against a porta potty rental cost if your budget is tighter than a trailer allows. Delivery is its own line item too, typically 100 to 500 dollars depending on distance and site access, so ask about that before you lock a date, and if the budget is tight, the porta potty rental per day page or the monthly porta potty rental page show what a simpler unit costs by comparison.
| unit type | day | week | weekend |
|---|---|---|---|
| trailer (standard to luxury) | 175 - 2,500 | 150 - 1,650 | 900 - 3,000 |
| trailer (event, multi-day) | -- | -- | 2,499 - 3,899 |
A 2 stall restroom trailer works for smaller gatherings, home renovations, or a weekend wedding where guest count stays under a hundred or so. A 4 stall restroom trailer handles bigger crowds without the line backing up, and it is the more common pick for corporate events or larger backyard parties around St. Louis. If your event tips past a few hundred guests, step up again to the 8 stall restroom trailer, which spreads traffic across more fixtures and keeps wait times down. Every trailer we place needs roughly 60 feet of straight clearance behind the delivery truck to back in and level safely, so tight driveways or alley access should get flagged when you request a quote, the same way we ask about clearance for a storage container rental or a 40ft storage container delivery. Compare stall counts directly on the 2 stall restroom trailer and 4 stall restroom trailer pages before you commit, since the wrong size either wastes money or leaves guests waiting. If you are still not sure how many fixtures you actually need, the how many porta potties do I need guide walks through headcount math that applies to trailers too.
For a wedding, yes, most people find the luxury upgrade worth the difference over a standard unit. A luxury restroom trailer rental brings finished interiors, real flooring, running water and a layout that does not feel like a job site amenity. St. Louis Porta Pros stocks these for wedding restroom rental bookings specifically because guests notice the difference between a basic trailer and one built for entertaining, and the same upgrade shows up in our deluxe flushable porta potty line for smaller budgets. If you want climate control, mirrors and a nicer sink setup, look at the luxury restroom trailer page for what is included at that tier. Luxury units also show up at golf tournament restrooms and upscale festival restroom rental setups, anywhere the client expects a step above a standard portable toilet rental. Pair the trailer with a handwashing station rental near the catering tent if you are also running a food truck or bar service, since guests washing hands before eating is a separate need from the restroom line itself.
Most trailers can run self-contained with an onboard freshwater tank and holding tank, but a hookup extends how long you can go between service visits. If hookups are not available on site, St. Louis Porta Pros brings water and holds waste in the trailer's own tank, similar to how a holding tank rental works for septic situations without sewer access. For longer events you may also want a temporary power pole or a light tower rental if the trailer sits somewhere without existing electrical service, especially for evening weddings or multi-day festivals, and a temporary fence rental or crowd control barrier rental often gets added at the same time to secure the area around it. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, which applies directly to construction sites using a restroom trailer instead of standard units. If your event or job site already has a spigot and a 200 amp panel nearby, tell us when you book, since it can lower the delivery complexity and sometimes the price.
Yes, a shower bathroom trailer is available for events or job sites running more than a single day, and it is a common add-on for disaster response crews or long-duration festivals. The shower trailer rental page covers stall counts and hot water setup for crews or guests who need to actually bathe, not just use a toilet. These get paired often with disaster relief sanitation deployments and with construction site services on projects running for weeks at a time. A shower trailer needs the same clearance and leveling considerations as a standard restroom trailer, plus a water heater cycle time you should ask about if you are running back-to-back showers for a full crew, and crews on longer jobs sometimes ask about septic pumping service or emergency septic service once the holding tank fills faster than expected. If your job site already has temporary fencing up for security, we coordinate delivery timing so the trailer lands inside the secured perimeter rather than outside it.
St. Louis Porta Pros delivers restroom trailers across the metro, from downtown event venues out to the surrounding suburbs, and most requests get a same-week delivery window.

Further out, we still reach Chesterfield at 19.2 miles west and St. Peters at 27.0 miles northwest, plus Granite City and Belleville across the river in Illinois, as well as Florissant and Webster Groves closer in. Check the service areas page for the full coverage map, or jump straight to a city page like porta potty rental in University City or porta potty rental in Kirkwood if you want city-specific pricing. For anyone still deciding between a full trailer and simpler units, the main porta potty rental in St. Louis hub compares both product lines side by side.
Confirm ground clearance, stall count, hookup availability and how long you actually need the unit, since those four answers drive almost every quote we build. Placement in the public right of way in St. Louis needs confirming with the city directly, so if your event spills onto a street or sidewalk, check with the city before delivery day rather than after. ADA Standards section 213.2 requires that where portable units are clustered, at least 5 percent of them be accessible, never fewer than one, which applies to trailer deployments with multiple stalls just as it does to standard unit banks; see ADA accessible porta potty for what an accessible unit needs to include, like the 60 inch turning circle under ADA Standards 304.3.1. Run through the porta potty rental checklist before you finalize anything, and if your event or job also needs waste removal, ask about a roll-off dumpster rental delivered the same day, or check dumpster sizes and dimensions and dumpster rental cost if you are not sure what size to order alongside the trailer.
A 4 stall restroom trailer typically covers a 150 guest wedding comfortably for a single evening event. If the reception runs longer than four or five hours or includes a full bar, consider stepping up to the 8 stall restroom trailer so lines do not form during peak hours.
Yes, though most crews use trailers for supervisors or office staff and keep standard porta potty rental units for the general workforce. OSHA 1926.51(c)(1) sets toilet ratios by crew size, one facility for 20 workers or fewer, and that ratio applies regardless of which unit type you choose.
Book as early as you can once your date is set, since luxury and larger trailers move fast during wedding and festival season. Standard weekday availability is usually easier to secure closer to the date than a weekend luxury unit.
Delivery is quoted separately based on distance and site access, generally in a 100 to 500 dollar range for a single trip. Confirm your address and any tight access points when you request a quote so the delivery fee is accurate upfront.
An event rate is a flat price for multi-day festivals or tournaments, typically 2,499 to 3,899 dollars, while a weekly rate applies to ongoing rentals billed by the week, from 150 to 1,650 dollars. Ask which structure fits your timeline before booking.
Yes, many customers add a separate portable sink rental or handwashing unit near food service areas even when the trailer already has an interior sink. 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing stations, not sanitizer alone.
