How Much Does a 4 Stall Restroom Trailer Cost?
Trailer pricing swings hard on duration and features, so get the exact numbers on the restroom trailer rental cost page before you commit. A day rental sits at the lower end of the trailer band, a weekend runs higher, and a full week costs more than either. Livermore Porta Pros prices the 4 stall unit against local jobsite and event demand, not a flat number pulled from a catalog.
| duration | typical range |
|---|---|
| day | 175 to 2500 |
| weekend | 900 to 3000 |
| week | 150 to 1650 |
Delivery is a separate line. Expect a delivery fee on top of the trailer rate, and confirm whether your site has the clearance a trailer needs. If you are also running a dumpster or fencing on the same lot, ask about bundling with roll-off dumpster rental or temporary fence rental to save a truck trip. Compare against a 2 stall restroom trailer or step up to an 8 stall restroom trailer if your headcount is closer to 400.
How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably cover 100 to 300 people over a single event day, more if it is a multi-day job site with steady rather than peak traffic. For construction crews, OSHA 1926.51(c)(1) sets the baseline: 1 toilet for 20 workers or fewer, then 1 seat and 1 urinal per 40 workers as headcount climbs past that. A 4 stall trailer often replaces six or more standalone units once you account for the sinks built into each stall. Not sure where your event or crew size lands? Run the numbers on how many porta potties do I need before you order. If your guest list includes guests using wheelchairs, ADA Standards section 213.2 requires at least one accessible unit in any cluster, and a standalone ADA accessible porta potty may need to sit alongside the trailer.
Where Can a 4 Stall Restroom Trailer Be Placed on Site?
Placement in Livermore comes down to ground clearance and utility hookups. Delivery trucks need roughly 60 feet of straight clearance behind the trailer to back in and level it, so walk your site before delivery day. Flat, firm ground matters. ADA Standards section 302.1 calls for stable, slip resistant surfaces, and that applies to the approach path even when the trailer itself is not the accessible unit. If the trailer needs to sit in a public right of way rather than a private lot, placement there needs confirming with the City of Livermore before delivery. For events with staged entry points, pair the trailer with a crowd control barrier rental to keep lines organized. Jobsites without existing power should also look at a temporary power pole or a light tower rental for evening shifts. Full placement guidance lives on the porta potty placement guide page, and it applies to trailers the same way it applies to standard units.
How does a 4 stall restroom trailer compare to renting four standard porta potties?
A trailer adds sinks, interior lighting and climate control that standalone units skip. Four standard porta potty rentals cost less upfront but lack running water. For weddings or corporate events in Livermore, the trailer reads far nicer to guests. Check the deluxe flushable porta potty option as a middle ground.
Does a 4 stall restroom trailer need a water and power hookup?
Most units carry an onboard tank and generator, but a direct hookup extends run time and cuts servicing visits. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any worksite. Ask Livermore Porta Pros whether your trailer ships self-contained or needs a spigot connection on delivery day.
Can I rent a 4 stall restroom trailer for a single-day event?
Yes. Day rentals are common for weddings, festival restroom rental needs and one-day fundraisers. Delivery and pickup usually happen the same day or the day before, so confirm setup timing when you book. Weekend rates apply if the trailer stays Friday through Sunday.
How often does the trailer get serviced during a multi-day rental?
ANSI/PSAI Z4.3 sets a baseline of one service visit per week for moderate use, but heavy weekend events often need mid-rental servicing. Livermore Porta Pros schedules service around your actual headcount rather than a fixed calendar, especially for construction site services running multiple weeks.
What is the difference between this and a luxury restroom trailer?
A luxury unit adds finishes like upgraded fixtures, sound systems or climate zones per stall. The luxury restroom trailer page breaks down what is included. A standard 4 stall unit covers function first; luxury covers presentation for weddings or VIP event areas.
