How many people can a 4 stall restroom trailer handle?
Four stalls split the load well for a wedding reception, a corporate picnic, or a mid-size job site crew. Norfolk Porta Pros bases the count on ANSI/PSAI Z4.3, the portable sanitation service standard that treats one facility per 10 users across a 40-hour week as the baseline interval. Push past 150 to 200 guests and it's worth stepping up to an 8 stall restroom trailer instead of doubling up on 4 stall units. Construction crews sizing toilets against headcount instead of stalls should check OSHA 1926.51(c), which sets ratios by worker count, not trailer size. For weddings specifically, our wedding restroom rental page walks through guest-count math in more detail, and general event sizing lives on how many porta potties do I need.
What does a 4 stall restroom trailer cost in Norfolk?
Trailer pricing moves with rental length, and a longer booking never costs less per day than a short one. Below is where a 4 stall unit typically lands next to its neighbors in the trailer lineup.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Multi-day event | $2,499 | $3,500 | $3,899 |
A single day rate covers a short job-site swap or a one-day filming block; check film set restroom rental if that's the use case. Weekend and event rates apply to weddings, festivals, and multi-day builds. Delivery is billed separately, and Norfolk Porta Pros quotes that against your address before confirming. Full cost breakdowns for every trailer size sit on restroom trailer rental cost, and general trailer specs are on restroom trailer rental.
Where can a 4 stall trailer be placed on site?
It needs a flat approach and roughly 60 feet of straight clearance behind the delivery truck, the same clearance our roll-off drivers ask for on a roll-off dumpster rental drop. Norfolk sites near the waterfront or older neighborhoods sometimes have narrow alleys or tight curb cuts, so it's worth walking the approach with our dispatcher before delivery day. Placement in the public right of way in Norfolk needs confirming with the city; we don't guess at that rule, and neither should you. For ADA needs on the same site, pair the trailer with an ADA accessible porta potty, since ADA Standards section 213.2 requires at least one accessible unit whenever single-user portables are clustered nearby. Ground surfaces under any unit should be stable and slip resistant per ADA Standards section 302.1. Full placement guidance is on our porta potty placement guide, and permit basics live at porta potty permit requirements.
Can a 4 stall trailer handle a construction crew instead of an event?
Yes. Crews running 40 to 80 workers often find four stalls cheaper per head than four separate standard units, especially over a multi-week job. Check construction site services and construction dumpster rental if you're already coordinating a roll-off on the same site.
Does the trailer need a water hookup?
It runs on an internal freshwater tank, no hookup required for most Norfolk deliveries. OSHA 1926.51(a)(1) still requires an adequate supply of potable water on any jobsite, which the trailer's tank satisfies on its own.
How far will Norfolk Porta Pros deliver a 4 stall trailer?
We service Norfolk directly and nearby communities including Hampton, about 12.6 miles north, and Chesapeake, roughly 23.0 miles south. See service areas for the full list.
What's the difference between a 4 stall and a 2 stall trailer?
A 2 stall restroom trailer suits small gatherings under 75 guests. Four stalls double the throughput for weddings, festivals, and larger crews without jumping to an 8 stall footprint.
Can I add handwashing separately instead of using the trailer sinks?
Yes, some events add a standalone unit anyway for high-traffic areas. See handwashing station rental and 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device at any washing station.
