A 4 stall restroom trailer serves crews and events where 2 units run short but a full luxury build is overkill, typically supporting groups from about 75 to 200 people depending on hours and duration. Hawthorne Porta Pros sets these on job sites, weddings and street fairs across Hawthorne, CA on flat, accessible pads, and the same crews handle everything from porta john rental to full construction site services.
Trailer pricing runs wide because stall count, run length and hookups all move the number. A single day rental sits between $175 and $2,500 depending on trailer class, while a full week lands closer to $1,397 typical, and weekend events booked Friday through Sunday commonly fall in the $900 to $3,000 range. For a longer event like a festival weekend, expect the restroom trailer rental cost to reflect stall count, freshwater capacity and any pump-out schedule, similar to how a porta potty rental cost shifts with duration.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
A 4 stall unit sits between the 2 stall restroom trailer and the 8 stall restroom trailer in both footprint and price, and delivery adds a separate line depending on distance and site access. Compare it against a standard bank of portable restroom rental units before deciding, since sometimes several standard stalls cost less than one trailer for a short job, and a look at porta potty rental per day pricing or monthly porta potty rental rates can confirm which route fits the budget.
Delivery crews need roughly 60 feet of straight clearance behind the truck to back a trailer into place, same as a roll-off delivery, so tight alleys or packed lots in Hawthorne can complicate placement. Walk the drop zone before delivery day, especially near curb cuts or landscaping, the same way you would for a temporary fence rental layout or a storage container rental drop. If your site cannot clear that distance, ask about porta potty placement guide options that use smaller equipment instead.
Accessible units matter here too. ADA Standards section 403.5.1 sets a 36 inch minimum clear route width, and section 404.2.3 requires a 32 inch clear door opening, so confirm your trailer's accessible stall meets both before booking for a public event. Where several single-user units cluster nearby, ADA Standards section 213.2 requires at least 5 percent to be accessible, never fewer than one. If ADA compliance is central to your event, look at the dedicated ADA accessible porta potty page for unit specs, and the broader ADA restroom requirements page covers the forward reach and turning circle rules too.
Placement in the public right of way needs confirming with the city before delivery day, since Hawthorne Porta Pros does not have a published local ordinance to cite here. If your trailer sits on private property, a permit usually is not required, but curb, sidewalk or street placement often is. Check current rules through the porta potty permit requirements page and confirm with the city directly rather than assuming, and if you are pairing the trailer with a bin, review dumpster permit requirements as well.
For job sites, OSHA 1926.51(c)(1) sets toilet ratios by crew size, one facility for 20 workers or fewer, scaling up from there. A 4 stall trailer often covers a mid-size crew without stacking standard units, and pairing it with a handwashing station rental keeps you aligned with 29 CFR 1910.141(d)(2), which requires soap and towels or a hand drying device, not sanitizer alone. Nearby projects in Lawndale, 2.3 miles south of Hawthorne, and Manhattan Beach, 5.2 miles west, use the same trailer classes for similar crew sizes.
It depends on event length and traffic pattern, but 4 stalls generally cover a crowd of 75 to 200 comfortably over a single day. For all-day festivals or multi-day builds, run the numbers through how many porta potties do i need before locking in stall count, and the OSHA portable toilet requirements page walks through the crew-size math for job sites.
Most 4 stall trailers run on onboard freshwater tanks and battery or generator power, so a hookup helps for longer events but is not always required. Ask about generator options when you request a quote for your dates.
A trailer has flushing fixtures, sinks and interior lighting, closer to indoor plumbing than a standard porta potty rental unit or even a deluxe flushable porta potty. It costs more but suits weddings, corporate events and long job sites where comfort matters.
Yes, day rentals are common for weddings and one-day festivals. Pair it with event restroom rental guidance to plan servicing, since a single day booking still needs a clean pad and level ground.
A luxury restroom trailer adds finishes like climate control and upgraded fixtures, while a standard 4 stall unit focuses on function. Both need the same 60 foot clearance and level pad described above.
