What Is a 4 Stall Restroom Trailer Good For?
Four stalls covers a crowd without turning your event into a bathroom line. Think backyard weddings, church functions, multi-day construction jobs, or a block party that outgrew a couple of standard porta potty rentals. Each stall typically includes its own door and sink setup, which spreads out traffic better than a bank of single units. If you're running a job site in Buena Park with a crew over 20 people, OSHA 1926.51(c) sets the toilet-to-worker ratio you need to hit, and a 4 stall trailer can satisfy that math while giving workers something nicer than a standard unit. For weddings and private events, pair it with a luxury restroom trailer upgrade if you want finished interiors instead of a working-crew feel. Compare it against the 2 stall restroom trailer if your guest count is smaller, or step up to the 8 stall restroom trailer for anything pushing past 150 guests.
How Much Does a 4 Stall Restroom Trailer Cost in Buena Park?
Pricing depends on how long you need it and what day of the week the job falls on. Here's what the range looks like:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Event rate | $2,499 | $3,500 | $3,899 |
A delivery fee applies on top of the trailer rate, and those run from 100 to 500 dollars depending on distance and site access. If your event is a single-day affair, check the restroom trailer rental cost page for a fuller cost breakdown, or look at the porta potty rental cost guide if you're weighing trailers against standard units. Buena Park Porta Pros quotes delivery based on your actual address, not a flat citywide number, since a job near La Mirada (4.1 miles north) costs differently to service than one closer to our yard.
Where Can the Trailer Be Placed on Site?
The trailer needs level, stable ground and a clear path in. ADA Standards section 302.1 calls for stable, firm, slip-resistant surfaces, which matters if you're setting this up on a gravel lot or a sloped backyard in Buena Park. If you're also renting a roll-off dumpster rental for the same job, remember a roll-off delivery needs about 60 feet of straight clearance behind the truck, so plan the layout before both trucks show up. For accessible units, ADA Standards section 213.2 requires that at least 5 percent of clustered single-user toilets be accessible, and if your event needs a fully accessible restroom instead of a multi-stall trailer, our ADA accessible porta potty page covers that separately. Need power run to the trailer? Check temporary power pole options, and if the site needs lighting after dark, light tower rental covers that too. For events needing a perimeter, see temporary fence rental.
How far in advance should I book a 4 stall restroom trailer?
Book as early as you can, especially for weekend weddings or festival dates when trailers move fast. Two to four weeks ahead is comfortable for most jobs. For last-minute needs, our emergency porta potty rental page covers faster turnaround options.
Does the trailer need a water hookup?
Some units connect to a water source; others run self-contained with onboard tanks. OSHA 1926.51(a)(1) requires potable water at the jobsite regardless of setup, so tell us your site conditions and we'll match the right configuration.
Can I get a 4 stall trailer for a construction site instead of an event?
Yes. Many job sites use them for crew comfort beyond what a portable toilet rental covers. Check construction site services or construction dumpster rental if you're bundling site needs together.
What's the difference between this and renting several standard units?
A 4 stall trailer offers private stalls, sinks and a more finished feel than a row of porta john rental units. It costs more but suits weddings and office-adjacent job sites better.
