How Many Stalls Does a 4 Stall Trailer Actually Have?
Four means four separate private stalls, each with its own door and fixture, so multiple guests or crew members use the trailer at once without a line backing up. That's a step above a standard porta potty rental and a step below the bigger 8 stall restroom trailer units we bring in for larger festivals. Compare it also against the 2 stall restroom trailer, which fits tighter driveways around Portsmouth but moves fewer people per hour. If you're deciding between trailer and standard units for a backyard wedding or a renovation crew, our how many porta potties do I need guide walks through headcount math, and OSHA 1926.51(c) sets the baseline ratio construction sites use: one toilet facility for 20 workers or fewer, scaling up from there. For events, see event restroom rental or the more specific wedding restroom rental page.
What Does a 4 Stall Restroom Trailer Cost in Portsmouth?
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| weekend | 900 | 2000 | 3000 |
| week | 150 | 1397 | 1650 |
| event | 2499 | 3500 | 3899 |
Day rates swing widely because a bare-bones unit and a climate-controlled luxury restroom trailer both fall in that band. Weekend pricing works as a flat package rather than a per-day multiple, which is why it doesn't slot into a table alongside day, week and month figures. For a full breakdown of what drives the number up or down, see restroom trailer rental cost or our general porta potty rental cost page. Delivery adds a separate line, and a roll-off style delivery needs about 60 feet of straight clearance behind the truck, so tell us about gate widths or tight alleys in Portsmouth before we schedule. If your event needs showers too, look at the shower trailer rental option instead.
Where Can a 4 Stall Trailer Be Placed on My Portsmouth Property?
Placement depends on ground stability and access, not just square footage. ADA Standards section 302.1 calls for floor and ground surfaces that are stable, firm and slip resistant, which matters on grass sites after rain. If you're required to provide an accessible unit alongside the trailer, ADA Standards section 213.2 says at least 5 percent of clustered single-user units, and never fewer than one, must be accessible. We pair many trailer rentals with a standalone ADA accessible porta potty to cover that. Our porta potty placement guide covers ground clearance and slope. Placement within the public right of way in Portsmouth needs confirming with the city before delivery day, so check with us early. Renovation jobs often add a construction dumpster rental or temporary fence rental alongside the trailer to keep the site contained.
How far in advance should I book a 4 stall trailer?
Book two to four weeks out for weekend events, longer around graduation and wedding season. Portsmouth venues fill fast in spring and fall. For rush jobs, our emergency porta potty rental page covers faster turnarounds, though trailer availability is tighter than standard units.
Does the trailer need a water and power hookup?
Most 4 stall trailers run on an internal freshwater tank and onboard power, no hookup required. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any workplace, which our tanks satisfy on delivery. Ask about temporary power pole options for longer stays.
Can I rent a 4 stall trailer for a construction site?
Yes. Many Portsmouth contractors pair one with a portable restroom rental cluster to meet crew size needs under OSHA 1926.51(c). See construction site services for a full site-services rundown covering fencing and storage too.
What's the difference between a 4 stall and a deluxe unit?
A 4 stall trailer has multiple private rooms; a deluxe flushable porta potty is a single flushing unit. Trailers suit larger guest counts; deluxe units suit smaller footprints where space in Portsmouth is limited.
Do I need a permit for a restroom trailer in Portsmouth?
Permit rules vary by site and location, and placement details need confirming with the city directly. Check our porta potty permit requirements page before booking, especially for street-facing or public right of way spots.
