What Comes Inside a 4 Stall Restroom Trailer?
Four separate stalls, running water, and interior lighting come standard, which puts this unit well above a standard porta potty rental in comfort. Compare it against a deluxe flushable porta potty if you need fewer stalls but still want a flush handle and a sink. Oceanside Porta Pros builds these for jobsites, weddings and festival restroom rental bookings where guests expect something closer to a real bathroom. If you are hosting a wedding restroom rental need with a formal layout, ask about the step up to a luxury restroom trailer. For construction crews, this trailer pairs well with a handwashing station rental and fits the broader construction site services package most contractors already order. Smaller footprint options include the 2 stall restroom trailer, and larger jobs move up to the 8 stall restroom trailer.
How Much Does a 4 Stall Restroom Trailer Cost in Oceanside?
Pricing depends on duration and how far the delivery truck has to travel.

A delivery fee applies on top of the trailer rate, and weekly delivery runs $50 to $150 depending on the drop-off distance. Full breakdowns live on the restroom trailer rental cost page, and general per-unit pricing across all our equipment sits on the porta potty rental cost page. If your event runs several days, check the porta potty rental per day page for a side by side comparison before you commit to a weekend block.
Where Can We Place a 4 Stall Restroom Trailer in Oceanside?
Placement needs firm, level ground and enough clearance for the delivery vehicle, since a roll-off style trailer needs about 60 feet of straight clearance behind the truck to back in safely. Oceanside sites near the coast can have soft or sloped ground, so walk the spot with your driver before delivery day. If the trailer serves a public event, at least one accessible unit should be part of the cluster under ADA Standards section 213.2, and the accessible route into it needs a minimum clear width of 36 inches per ADA Standards section 403.5.1. Our ADA accessible porta potty page covers stand-alone accessible units if the trailer alone will not cover code. Placement in the public right of way in Oceanside needs confirming with the city; we do not guess at that rule, so check our porta potty placement guide and the porta potty permit requirements page before you finalize a curbside spot. Crews near Camp Pendleton Mainside, about 11.6 miles north of Oceanside, often pair the trailer with temporary fence rental to secure the site overnight.
How many stalls do we actually need?
It depends on headcount and event length. Our how many porta potties do i need guide walks through the math, but four stalls generally covers up to a few hundred guests over a single weekend. Construction crews should also check OSHA portable toilet requirements under 1926.51(c).
Does the trailer need a water hookup?
No. It carries its own water and holding tank, so it runs independent of a house or venue hookup. That is part of why it works for remote sites and for jobs far from Oceanside proper, including sites out toward Bonsall, 12.4 miles northeast.
Can we rent it for just one day?
Yes. Day rentals exist for one-off events, though weekly and weekend rates often make more financial sense for anything spanning more than a single day. See the pricing table above for the current bands.
Is a service visit included during a multi-day rental?
Service intervals follow the ANSI/PSAI Z4.3 baseline of one visit per week for lighter use, though heavy weekend events usually need more frequent service. Ask us to schedule extra visits when you book.
Do we need a permit to place the trailer?
Possibly, depending on where it sits. Oceanside permit rules for right-of-way placement are not something we guess at here; confirm with the city and read our porta potty permit requirements page for the general process.
