Ontario Porta Pros rents restroom trailers from 2-stall units to 8-stall luxury models, with prices in this market running from about 175 dollars a day for a short job to 3500 dollars for a multi-day event package. Weddings, corporate lots, and long construction jobs all use different sizes. Here's how to pick.
Cost depends on stall count, trip length, and whether you want flush plumbing or a shower-bathroom trailer combo. A basic day rate can run as low as 175 dollars, but most Ontario renters land in the 800 dollar range per day once delivery and a generator hookup get added. Weekly rentals average close to 1,397 dollars, and full weekend events often run 900 to 3,000 dollars depending on stall count and finish level. Multi-day festival or wedding packages, the kind that need a luxury restroom trailer with climate control and finished interiors, run 2,499 to 3,899 dollars for the full event window. Check our restroom trailer rental cost breakdown for a fuller table, or compare against a standard porta potty rental if your budget is tighter than the job needs.
| unit | duration | low | typical | high |
|---|---|---|---|---|
| trailer | day | 175 | 800 | 2500 |
| trailer | weekend | 900 | 2000 | 3000 |
| trailer | week | 150 | 1397 | 1650 |
| trailer | event | 2499 | 3500 | 3899 |
Delivery adds its own line item, typically 100 to 500 dollars for a single day trip depending on distance and site access. If you're comparing against porta potty rental cost in general, trailers cost more but skip the line entirely, which matters for weddings and VIP events.
Most homeowners and small contractors do fine with a 2 stall restroom trailer, which handles light traffic events under 75 guests or a small renovation crew. A 4 stall restroom trailer covers weddings up to around 150 guests or a mid-size jobsite. Once you're past 200 people, or running a multi-day festival, step up to an 8 stall restroom trailer. OSHA 1926.51(c)(1) sets the baseline for construction toilet counts: one facility per 20 workers or fewer, one seat and one urinal per 40 workers between 20 and 200, and one per 50 above that. That standard is written for portable toilets, but it's the ratio most site managers use to size a trailer, too. If your event has a mixed crowd needing full privacy and finished stalls rather than a construction site, our event restroom rental page walks through count planning differently than a jobsite would. Not sure where you land? The how many porta potties do I need guide applies the same headcount logic to trailers.
Yes. A shower bathroom trailer combines toilet stalls with private shower units, and it's the standard choice for disaster relief camps, film sets, and multi-day outdoor weddings where guests or crew need to clean up on-site. Our shower trailer rental page covers unit layouts. These run on the higher end of the trailer pricing band since they need larger water tanks and drain capacity, and most Ontario bookings for shower trailers fall into the weekend or weekly duration rather than a single day. If you're staging a longer film shoot, pair it with our film set restroom rental page, and if it's a disaster response deployment, see disaster relief sanitation for setup notes specific to that use case.
A luxury restroom trailer buys finished interiors, running water, climate control, and stall privacy that a standalone unit can't match, which matters most for weddings, galas, and corporate events where guest experience is part of the budget. Our luxury restroom trailer page has photos and layouts. Weekly luxury trailer rentals in this market run from 150 to 1,650 dollars depending on stall count and finish, and full weekend luxury bookings often land between 900 and 3,000 dollars. Compare that against a deluxe flushable porta potty, which gives you flush plumbing in a single-stall footprint for a fraction of the cost, if you don't need the full trailer experience. For a golf tournament or wedding where guests will judge the venue by the restrooms, see golf tournament restrooms or wedding restroom rental for use-case specific setup advice.
Every trailer needs level, stable ground, per ADA Standards section 302.1, which requires floor and ground surfaces to be stable, firm, and slip resistant, whether or not the unit itself is ADA-configured. Delivery trucks generally need roughly 60 feet of straight clearance behind the vehicle to back a trailer into position safely, the same clearance rule that applies to roll-off dumpster rental drops. If the unit will draw hardwired power rather than run on a built-in generator, check with your site electrician about amperage before delivery day; our temporary power pole page covers standalone power options for remote sites. Accessible units built to ADA Standards section 404.2.3 need a minimum 32 inch clear door opening, and where several units cluster, ADA Standards section 213.2 requires at least 5 percent of units, and never fewer than one, to be accessible. See ADA accessible porta potty or ADA restroom requirements if your event needs to meet that ratio.
Placement in the public right of way, on a street or sidewalk, needs confirming with the City of Ontario before delivery; we haven't verified a specific local ordinance for trailer siting, so check with the city directly rather than assume. Most residential driveway and private lot placements don't trigger the same review, but construction sites and street closures usually do. Our porta potty permit requirements page has the general framework, and dumpster permit requirements covers the parallel process for roll-off placement, which follows similar right-of-way logic in most cities. If your event sits on private property with off-street parking, like a backyard wedding or a fenced construction lot, permitting is rarely an issue. Renters near Eastvale, about 6.8 miles south of Ontario, or Upland, 8.3 miles northwest, should still confirm with their own city rather than assume Ontario's rules apply across the line.
Ontario Porta Pros delivers restroom trailers across Ontario and into nearby cities, including Eastvale 6.8 miles south, Montclair 7.4 miles northwest, Upland 8.3 miles northwest, and Jurupa Valley 9.0 miles east. If you're searching for a mobile restroom trailer rental near a specific venue, our service areas page lists coverage by city, and our geo pages for Eastvale, Montclair, Upland, and Jurupa Valley cover porta potty delivery in those areas specifically. For general Ontario delivery, start at Porta Potty Rental in Ontario, CA or our main page to see what's available same week. Same-week booking is common for weekday events, but weekend luxury trailer bookings should go in early since inventory is limited compared to standard units.
A 2 stall restroom trailer typically runs in the lower part of the trailer pricing band, often starting under 200 dollars for a single weekday and climbing from there depending on delivery distance and rental length. Weekly rentals for smaller trailers tend to sit toward the lower end of the 150 to 1,650 dollar range. Confirm exact pricing with a quote since site access affects delivery fees.
A restroom trailer has multiple enclosed stalls, running water, and often climate control, built into a towable unit, while a portable toilet rental is a single self-contained stall with a holding tank. Trailers cost more but offer privacy and comfort standard units can't match, which matters for weddings and VIP guests. Both serve the same basic function otherwise.
A 4 stall restroom trailer typically covers a wedding around 150 guests comfortably, though guest mix and event length matter too. Longer receptions with alcohol service tend to need more capacity than a quick ceremony. Our how many porta potties do I need guide has headcount ratios that apply to trailer sizing as well.
Most restroom trailers include a built-in generator for lighting, water pumps, and climate control, so a separate power hookup usually isn't required. Some larger luxury units on longer bookings can tie into site power instead if it's available and rated correctly. Ask when booking whether your unit is self-powered or needs a hookup.
Standard trailers are often available within a few days, but luxury and multi-stall units for weekend events should be booked further ahead since inventory is limited. Emergency situations, like a failed septic system before an event, can sometimes be accommodated faster. Check emergency porta potty rental for urgent standard unit availability if a trailer isn't ready in time.
A shower bathroom trailer includes private shower stalls plus toilet facilities in one unit, built for multi-day events, disaster response, or film sets where people need to clean up on-site. Water tank size and hookup requirements are larger than a standard restroom trailer. See shower trailer rental for specific configurations available in Ontario.
