Ontario Porta Pros rents standard units, ADA-accessible stalls and full restroom trailers across Ontario, with standard portable restroom rental starting around $100 a day. Whether it's a backyard party, a construction site or a multi-day festival, the right unit depends on headcount, duration and whether guests expect running water.
A standard portable toilet is what most people picture: a single stall, roughly 44 by 48 inches on the ground and about 92 inches tall, with a 60 to 70 gallon holding tank. It works for job sites, yard work and casual gatherings where guests won't mind a self-contained unit. A portable restroom trailer rental is a different animal entirely. Think flushing toilets, sinks with running water, sometimes climate control and mirrors. If you're searching for a portable restroom trailer rental near me because you're hosting a wedding, a corporate event or a family reunion, the trailer is almost always the better call. A 2-stall portable restroom trailer handles smaller gatherings, while 4-stall and 8-stall options scale up for larger crowds. For something closer to a hotel bathroom, ask about the luxury restroom trailer or the deluxe flushable porta potty, which comes in around $85 to $1200 a day depending on features and rental length.
Guest count and event length drive the number, not guesswork. OSHA 1926.51(c) sets a construction-site benchmark of one toilet for every 20 workers on an eight-hour shift, and ANSI/PSAI Z4.3 uses a similar baseline of one unit per 10 users over a 40-hour week for planning purposes. A backyard party in Ontario with 40 guests over four hours needs less than a full crew of laborers working all week, so don't just copy job-site math onto a party headcount. For a portable restroom rental for party use, we usually walk through guest count, whether alcohol is served, and how many hours the event runs. Our full breakdown lives at how many porta potties do I need. If the party includes guests with mobility needs, ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, with a minimum of one. Our ADA accessible porta potty units meet that standard, and the ADA restroom requirements page walks through the specifics for ada portable restroom trailers too.
Pricing depends on unit type and how long you need it. Here's what the numbers look like across our most requested options:
| Unit | Day | Week | Month |
|---|---|---|---|
| Standard | $100 - $350 | $130 - $500 | $125 - $325 |
| Deluxe flushable | $85 - $1200 | $150 - $290 | - |
| ADA-accessible | $200 - $400 | $240 - $500 | - |
Restroom trailers run separately, from around $175 a day up to several thousand for a multi-day event package, and delivery fees typically land between $100 and $500 depending on distance and job complexity. For a party weekend specifically, expect a flat weekend rate rather than a per-day multiplier. Full pricing detail, including what drives the low end versus the high end, is on our porta potty rental cost and restroom trailer rental cost pages. If you need something for 30 days or longer, the monthly porta potty rental page breaks down how the math changes.
Standard units don't need either. They're self-contained, which is why they work on raw land, construction lots and remote event sites. Restroom trailers are different: flushable models need either a water tank fill or a hose bib connection, and larger trailers with lighting and climate control may need a dedicated power drop, which is where a temporary power pole comes in handy. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, which matters if you're staffing a job site rather than hosting a private party. Handwashing is a separate question from the toilet itself: 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, and hand sanitizer alone doesn't satisfy that. We pair many trailer and standard unit rentals with a handwashing station rental or a standalone portable sink rental for exactly that reason. If your project involves painting, coatings or pesticide application, OSHA 1926.51(f)(1) requires washing facilities for those specific contaminant exposures.
Delivery in Ontario is straightforward for most residential and commercial sites, and we also cover Eastvale about 6.8 miles south, Montclair 7.4 miles northwest, Upland 8.3 miles northwest and Jurupa Valley 9.0 miles east. If you're outside Ontario proper, check service areas for full coverage, or start with the porta potty rental Ontario hub page for city-specific detail. Not every renter is planning a one-time party. Ongoing construction crews should look at construction site services, while anyone remodeling a home might prefer the shorter-term home renovation porta potty option instead of a full trailer.
Book as early as you can, especially for weekend events. Trailers are a smaller inventory pool than standard units, and weekend and event-day demand fills fast. For a wedding or festival date already set months out, reserving four to six weeks ahead gives you the best shot at the trailer size and features you want.
Yes. A single standard unit works fine for gatherings under 50 guests over a few hours. If you want something nicer for mixed-age or dressier events, a single-stall deluxe flushable unit is a common upgrade without jumping to a full trailer.
Yes, with some prep. Water lines need protection from freezing, and heated models exist for winter events. Check porta potty in winter for details on cold-weather setup for both trailers and standard units.
Nothing structural. "Portable restroom" and "porta potty" describe the same standard unit; "restroom trailer" refers to the larger, plumbed alternative. Our portable toilet rental and porta john rental pages use these terms interchangeably because customers search both ways.
Placement in the public right-of-way needs confirming with the City of Ontario before delivery. For private property setbacks, see porta potty permit requirements and our general porta potty placement guide for spacing and access guidance.
Yes. Ontario Porta Pros delivers portable restroom rental across Ontario and the surrounding metro, with same-day and next-day drop-off available on most orders.
