How many people can a 4 stall restroom trailer handle?
Four stalls comfortably serve a mid-size crew or a guest list without long lines, roughly the jump point between a bank of standard porta potty rental units and a full 8 stall restroom trailer. ANSI/PSAI Z4.3 sets a baseline service interval of once a week for every 10 users across a 40 hour week, which is the number Richmond Porta Pros uses to plan servicing on multi-day rentals. For a wedding at a Richmond venue, four stalls generally cover 100 to 150 guests over an evening. Contractors running two crews on a Richmond job site often pair this trailer with a luxury restroom trailer upgrade when clients want sinks with running water instead of a standard unit. If you are unsure which count fits your headcount, the how many porta potties do I need guide walks through it, and construction crews should also check OSHA portable toilet requirements against OSHA 1926.51(c), which sets ratios of one toilet per 20 workers up to certain crew sizes.
What does a 4 stall restroom trailer cost in Richmond, CA?
Pricing depends on trailer finish and rental length, and the table below reflects the bands Richmond Porta Pros quotes most often.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2,500 |
| Week | 150 | 1,397 | 1,650 |
| Event | 2,499 | 3,500 | 3,899 |
A weekend rental typically lands between 900 and 3,000 dollars depending on trailer class and add-ons. Delivery is billed separately and generally falls between 100 and 500 dollars for a single day, sometimes less for week-long jobs. For a full cost breakdown across trailer sizes, see restroom trailer rental cost, or compare against a smaller 2 stall restroom trailer if your guest count is lighter. Event organizers planning a Richmond festival or fair should also look at event restroom rental and festival restroom rental for site layout tips.
Where can a 4 stall restroom trailer be placed on site?
Placement needs firm, level ground and enough clearance for the delivery truck to back in and level the trailer, similar to the 60 feet of straight clearance a roll-off delivery needs behind the truck. ADA Standards section 405.2 caps ramp slope at 1:12, so any ramped entry into an accessible unit has to meet that grade, and ADA Standards section 304.3.1 requires a 60 inch turning circle inside an accessible stall. If your event needs an ADA-compliant unit alongside the trailer, pair it with an ADA accessible porta potty rather than assuming the trailer covers that requirement alone. Placement in the public right of way in Richmond needs confirming with the city before delivery day; check porta potty permit requirements or dumpster permit requirements if the same job also needs a roll-off. For general layout logic, the porta potty placement guide applies to trailers too, and jobs running temporary fencing around the unit can add it through temporary fence rental.
Does a 4 stall restroom trailer need water and power hookups?
Most trailers run on an internal freshwater tank and battery lighting, but a garden hose hookup extends run time for multi-day events. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, which matters on construction sites using the trailer. If you need dedicated power for lighting or climate control, ask about a temporary power pole alongside the trailer.
How far in advance should I book a 4 stall restroom trailer in Richmond?
Book two to four weeks out for weddings and festivals, sooner for peak summer weekends. Contractors on ongoing Richmond jobs can set up recurring service instead. Emergency same-day delivery is sometimes possible; check emergency porta potty rental for availability.
Can I get a shower trailer instead of a restroom-only unit?
Yes. Richmond Porta Pros offers a separate shower trailer rental for disaster relief, camps or multi-day crews needing to wash up, distinct from the toilet-only trailer line.
What is the difference between a 4 stall and 8 stall trailer?
An 8 stall trailer doubles capacity for larger weddings, concerts or fairs. See 8 stall restroom trailer for specs and pricing if your Richmond event tops 150 guests.
Do I need a permit to place a restroom trailer in Richmond, CA?
Sometimes, depending on where it sits relative to the street or sidewalk. Confirm with the city before delivery; Richmond Porta Pros can advise based on the address.
