What Comes With a 4 Stall Restroom Trailer?
Four separate stalls, running water, and enough flow to keep a wedding or a job site moving without anyone waiting outside in the cold. Compare that to a single standard porta potty rental, which holds a 60 to 70 gallon tank and works fine for one crew but bottlenecks fast once you've got more than a handful of people. A trailer spreads that load across four stalls instead of one. If you need something nicer than the basic unit but don't need four stalls, look at the deluxe flushable porta potty instead. For bigger guest counts, the 8 stall restroom trailer is the next step up, and the 2 stall restroom trailer is the smaller option. Every trailer we set in Amherst gets checked for a level pad and clear access before delivery day, same as we'd do for any restroom trailer rental we deliver.
How Much Does a 4 Stall Restroom Trailer Cost in Amherst?
Trailer pricing depends heavily on duration and finish level. Here's what the data shows across trailer rentals generally:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Event | $2,499 | $3,500 | $3,899 |
A single weekend wedding usually lands closer to the weekend rate above, while a multi-week construction job in Amherst often pencils out cheaper per day on the week rate. Check the restroom trailer rental cost page for a fuller breakdown, or see how trailer costs stack against standard units on the porta potty rental cost page. Delivery adds a separate fee, typically $100 to $500 depending on distance and site access; get a firm number through request a quote.
Why Does a 4 Stall Trailer Need So Much Clearance?
Because it's towed in on a chassis, not carried. A roll-off delivery truck needs about 60 feet of straight clearance behind it to back in safely, and a restroom trailer needs similar room to maneuver on site. Tight driveways in older Amherst neighborhoods sometimes can't manage that, so we ask about site access before we quote. If your event site is closer to Tonawanda, which sits about 9.0 miles west of Amherst, or North Tonawanda at 9.3 miles northwest, we still run the same clearance check before confirming delivery. Accessible trailers also have to meet real standards: ADA Standards section 403.5.1 calls for a 36 inch clear route, and section 404.2.3 requires a 32 inch clear door opening, so if you need an ADA stall built into the trailer, say so up front. For construction sites running a 4 stall trailer instead of scattered standalone units, OSHA 1926.51(c) still sets the toilet-to-worker ratio you're required to hit, one facility for 20 workers or fewer. Full breakdown on the OSHA portable toilet requirements page.
How many people can a 4 stall restroom trailer handle?
Four stalls comfortably cover a wedding of 100 to 150 guests over a few hours, or a construction crew under the OSHA 1926.51(c) ratio without doubling up on standalone units. For bigger counts, step up to the 8 stall restroom trailer or ask about pairing units.
Does a 4 stall trailer need a hookup?
Most trailers we place in Amherst run self-contained with onboard tanks and a generator, no hookup required. If your site has power and water already, we can wire in and skip the generator; ask when you request a quote.
Can I rent a 4 stall trailer for a construction site?
Yes. It covers the OSHA 1926.51(c) ratio for a mid-size crew in one unit instead of several standalones. Pair it with a roll-off dumpster rental and a temporary fence rental for a full site setup.
What's the difference between this and a luxury trailer?
Finish level and fixtures. A luxury restroom trailer adds upgraded interiors and climate control for higher-end events; a standard 4 stall unit covers the same stall count at a lower price point.
How far in advance should I book?
Book as early as you can for weekend events, since trailer availability tightens fast around Amherst wedding season. For urgent needs, check emergency porta potty rental for faster turnaround options.
