How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably cover crowds from roughly 75 to 150 guests over a few hours, depending on how food and drink are flowing. For a wedding at a venue outside the city, or a corporate event downtown, that range holds. If you're planning something bigger, step up to the 8 stall restroom trailer, or size down with the 2 stall restroom trailer for a smaller backyard gathering. West Palm Beach Porta Pros walks through headcount and hours before quoting, because a trailer sized wrong is the most common complaint we hear, and the same sizing logic applies whether you're planning a festival restroom rental or a wedding restroom rental. For work crews instead of guests, OSHA 1926.51(c) sets toilet ratios by worker count on construction sites, and that math runs differently than an event guest list. If you're not sure which side of that line you're on, the construction site services page and the event restroom rental page split the two use cases out, and the OSHA portable toilet requirements guide covers worker-count math in more detail.
What Does a 4 Stall Restroom Trailer Cost in West Palm Beach?
Pricing depends on how long you need it and whether it's a single day or a full weekend event.
| duration | typical range |
|---|---|
| day | $175 to $2,500 |
| week | $150 to $1,650 |
| weekend | $900 to $3,000 |
| event (multi-day) | $2,499 to $3,899 |
Delivery is quoted separately and depends on distance and site access, similar to how a roll-off dumpster rental or temporary fence rental gets priced for the same job site. West Palm Beach Porta Pros services Riviera Beach 6.5 miles northeast, Palm Springs 9.5 miles south, Royal Palm Beach 9.9 miles southwest, Greenacres 10.8 miles south and Lake Worth Beach 14.8 miles southeast, so if your event sits outside city limits, distance still factors into the quote.

Do You Need Extra Units for ADA Access?
Yes, if you're clustering portable restrooms rather than renting a single accessible trailer stall. ADA Standards section 213.2 requires that where single-user units are grouped, at least 5 percent, and never fewer than one, be accessible. A 4 stall trailer with a dedicated accessible stall built in can satisfy that on its own, but confirm the layout before booking, and the porta potty rental checklist is a useful gut check before you sign off. The route to the trailer also matters: ADA Standards section 403.5.1 calls for a 36 inch clear path, and section 405.2 caps ramp slope at 1:12, both worth checking on grass or gravel sites around West Palm Beach. If your event needs a standalone accessible unit instead of a built-in stall, the ADA accessible porta potty page covers that option, and ADA restroom requirements goes deeper on the standard itself.
Delivery trucks need about 60 feet of straight clearance behind the unit to place a trailer or roll-off safely, so tight urban lots in West Palm Beach sometimes need a placement walk-through first. The porta potty placement guide covers ground clearance and leveling in more detail, and how many porta potties do i need helps if you're comparing a trailer against standard porta potty rental units for the same headcount, or against a shower trailer rental if guests need to clean up too.
Frequently asked questions
How long can I rent a 4 stall restroom trailer for?
Anywhere from a single day to a multi-day event booking. Day, week and weekend rates all differ, and full event pricing covers multi-day festivals or weddings. West Palm Beach Porta Pros sets the term around your actual event dates, not a fixed minimum.
Does the trailer need a water and power hookup?
It needs a nearby water source and standard power for lighting, sinks and climate control inside. If your site has neither, ask about a self-contained setup when you request a quote.
Can I add a handwashing station alongside the trailer?
Yes. Many events add a separate handwashing station rental near a food or bar area even with sinks inside the trailer, since guest flow moves faster with a second wash point, and a portable sink rental works as a lighter-weight option for smaller gatherings.
What's the difference between this and a luxury trailer?
A 4 stall unit covers function first. The luxury restroom trailer option adds finish details like upgraded fixtures and interior design, usually for upscale weddings.
Is delivery included in the quoted price?
No, delivery is quoted separately based on distance and site access. Request a firm number through request a quote once you know your date and location, or check contact if you have questions before booking.
