An 8 stall restroom trailer covers events and job sites running 250 to 500 people a day without a line forming at the door. Ontario Porta Pros builds these units for weddings, festivals, and multi-week construction jobs, and weekly rental for a comparable trailer setup runs from about $150 to $1,650 depending on trailer class and duration. Bigger crews need restroom trailer rental, not stacked single units.
Eight working stalls, split between men's and women's sides, sometimes with a separate ADA-compliant stall built into the layout. That configuration handles guest counts that would otherwise need eight to ten separate standard porta potty rental units spread across a site, minus the walk time between them. For weddings and corporate events near Ontario, this is usually the jump-up size once a 2 stall restroom trailer or 4 stall restroom trailer can't keep pace with guest flow. Interior doors run wider than a standard porta potty's, and ADA Standards section 404.2.3 sets minimum clear door opening width at 32 inches for any accessible stall in the unit. We check clearance before delivery, especially on sites near Eastvale, 6.8 miles south, where lot access can be tight.
Trailer pricing depends heavily on class and rental length, and the table below reflects the broad range we see across finish levels.
| duration | low | typical | high |
|---|---|---|---|
| day | $175 | $800 | $2,500 |
| weekend | $900 | $2,000 | $3,000 |
| week | $150 | $1,397 | $1,650 |
| event (multi-day) | $2,499 | $3,500 | $3,899 |
A single-day rental sits at the low end of that range; a multi-day festival package sits at the high end. For a full cost breakdown across trailer sizes, see restroom trailer rental cost or compare against smaller units on the porta potty rental cost page. If your event only needs flushable comfort without full trailer scale, look at deluxe flushable porta potty options instead.
Yes, on both counts, and this is where planning saves a headed-off delivery problem. Most 8 stall trailers need a level pad and either a garden-hose water connection or an onboard freshwater tank, plus a place to route greywater. Power draw varies by trailer, so ask what amperage your unit pulls before the truck shows up; some units run off standard outlets, others want dedicated circuits similar to what you'd spec for a temporary power pole or light tower rental. Delivery trucks for larger trailers need clearance similar to roll-off service, and our roll-off dumpster rental drivers apply the same rule: about 60 feet of straight clearance behind the truck to back in safely. We've delivered into venues from Ontario proper out toward Upland, 8.3 miles northwest, and Montclair, 7.4 miles northwest, so we plan the approach ahead of the site visit, not on the day of.
For crowd events, ADA Standards section 213.2 requires that where portable units are clustered, at least 5 percent be accessible, never fewer than one, and that carries over to trailer stall counts too. Pair the trailer with temporary fence rental to control queue lines, and if the event runs food service, a handwashing station rental keeps you compliant separate from the trailer's interior sinks. Larger festivals booking through Ontario Porta Pros often add a storage container rental for supplies and a holding tank rental as backup capacity.
Two to four weeks out is safe for most weekends; peak wedding and festival months tighten that window fast. Ontario Porta Pros holds inventory across trailer classes, but the nicer finish levels book first. Confirm your date through request a quote rather than waiting.
Usually yes if the surface is level and compacted; soft or sloped ground causes leveling problems. ADA Standards section 302.1 requires the accessible route surface be stable, firm and slip resistant, so we may ask for plywood or matting under stabilizer jacks on looser ground.
Trailers offer real sinks, mirrors, and often climate control; stacked portable restroom rental units are cheaper per unit but lack that comfort. For long job sites, several standard units plus a handwashing station rental can cost less than a trailer.
Yes. Service intervals depend on guest count and event length; ANSI/PSAI Z4.3 sets a baseline of one service visit per week for lighter usage, but multi-day events typically need daily servicing, which we schedule as part of the event restroom rental package.
Not always. Delivery fees run separately depending on distance and site access, generally between $100 and $500 for a single day. Ask for delivery cost when you request your quote through contact.
