How many people can a 4 stall restroom trailer handle?
Four stalls comfortably cover a wedding of 100 to 150 guests, or a work crew that would otherwise need several standard porta potty rental units spread across a site. OSHA 1926.51(c)(1) sets construction ratios at one toilet facility for 20 or fewer workers, so a 4 stall trailer can cover a crew in that range with room for site flow. For weddings and private events, check wedding restroom rental or event restroom rental for guest-count guidance specific to New Bedford gatherings.

What does a 4 stall restroom trailer cost in New Bedford?
Trailer pricing depends heavily on duration and how the unit is finished inside. A day rental sits well under a full week, and a multi-day event booking runs higher than either because of setup and teardown labor. New Bedford Porta Pros prices by the job, not a flat sheet, so get exact numbers through request a quote.
| Duration | Typical Range |
|---|---|
| Day | $175 - $2,500 |
| Week | $150 - $1,650 |
| Event (multi-day) | $2,499 - $3,899 |
For a broader breakdown across trailer sizes, see restroom trailer rental cost, and compare against basic porta potty numbers at porta potty rental cost or porta potty rental per day. Longer construction jobs sometimes do better with monthly porta potty rental instead of a trailer, depending on crew size and budget.
Where can a 4 stall trailer be placed on site?
The trailer needs level, stable ground, similar to the surface standard under ADA Standards section 302.1, which calls for stable, firm and slip-resistant footing. Delivery crews generally want clear approach space to back the trailer in, comparable to the roughly 60 feet of straight clearance a roll-off truck needs for a roll-off dumpster rental delivery. If the unit needs to be ADA accessible, an accessible route needs a minimum 36 inch clear width per ADA Standards 403.5.1, and any door opening needs to clear 32 inches under ADA Standards 404.2.3. New Bedford sites near the waterfront or on gravel lots should flag ground conditions early. Placement in the public right of way needs confirming with the city before delivery day; New Bedford Porta Pros can talk through options once a site address is on file, and porta potty permit requirements covers what to check ahead of time. For sites that also need power, temporary power pole and light tower rental are worth pairing with the trailer request.
New Bedford job sites near Acushnet Center, about 3.3 miles northeast, and Fairhaven, 4.9 miles southeast, use the same delivery routes New Bedford Porta Pros runs for standard trailer service. Dartmouth sits 10.7 miles south if your site falls on that side of the city.
Frequently asked questions
How is a 4 stall trailer different from stringing together single units?
A trailer gives users a private, enclosed stall with a sink inside, closer to a real restroom than a row of portable toilet rental units. It also concentrates cleaning and pumping into one visit instead of several stops.
Does the trailer need a water and power hookup?
Most trailers run on an internal fresh water tank and a small generator or standard outlet, so a hookup isn't required. OSHA 1926.51(a)(1) requires an adequate supply of potable water at the jobsite regardless of source.
How often is a 4 stall trailer serviced?
ANSI/PSAI Z4.3 sets one weekly service visit as the baseline for units serving up to 10 users over a 40 hour week. Higher guest counts or multi-day events usually need extra service calls.
Can we get an ADA accessible stall added?
Yes. Where units are clustered, ADA Standards section 213.2 requires at least 5 percent to be accessible, never fewer than one. Ask about pairing an ada accessible porta potty alongside the trailer for larger events.
What is the difference between a 4 stall and an 8 stall trailer?
An 8 stall trailer roughly doubles capacity for larger festivals or big work crews. Check 8 stall restroom trailer for guest-count comparisons before booking.
