What comes inside a 4 stall restroom trailer?
Each stall is private, with its own door and sink, and the trailer runs on a fresh water tank rather than a chemical holding system alone, which is what separates it from a standard porta potty rental. Compare it to a 2 stall restroom trailer if your headcount runs smaller, or step up to an 8 stall restroom trailer for anything past 300 guests. Fontana Porta Pros builds these out with the same attention given to a luxury restroom trailer, just scaled for mid-size jobs. Ground surfaces need to meet ADA Standards section 302.1, stable, firm and slip resistant, whether you're setting up in a gravel lot or a paved yard in Fontana. Anyone renting for a jobsite should also read up on construction site services so plumbing, power and fencing line up on delivery day.
How much does a 4 stall restroom trailer cost in Fontana?
Pricing runs by the day, the week, or full event rental, and jumps depending on trailer class and how long you keep it. A basic unit rents differently than a deluxe flushable porta potty upgrade path, so check the table below against your event length before booking.
| 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 in Fontana typically lands between $900 and $3,000 depending on trailer size and hookup needs. For the full cost breakdown across trailer types, see restroom trailer rental cost, and general porta potty budgeting lives at porta potty rental cost. Delivery adds a separate fee, and service fees for weekend jobs run $400 to $1,200 on top of the unit price, so ask Fontana Porta Pros for a full quote before you commit to a date.
Do I need an accessible unit alongside the 4 stall trailer?
Yes, if you're clustering portable facilities for a public event. ADA Standards section 213.2 requires at least 5 percent of clustered single-user portable toilet units be accessible, with a minimum of one, so pair your trailer with an ADA accessible porta potty rather than assuming the trailer itself covers the requirement. Accessible routes need 36 inches of clear width under ADA Standards section 403.5.1, and doorways need at least 32 inches under section 404.2.3, both worth checking against your site layout before delivery. Construction crews juggling this alongside toilet counts should read OSHA portable toilet requirements, since OSHA 1926.51(c)(1) sets separate ratios for job sites: one facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers past that. Weddings and parties in Fontana lean toward wedding restroom rental or event restroom rental pages for guidance on guest counts instead.
If your event pulls from Bloomington, 7.0 miles southeast, or Jurupa Valley at 11.2 miles south, Fontana Porta Pros can still deliver same day in most cases. Colton sits 11.6 miles southeast and Upland 12.5 miles west, both within normal delivery range. Check service areas for the full coverage map, or browse nearby city pages like porta potty rental in Bloomington if your job spans two cities.
How many people can one 4 stall restroom trailer handle?
Four stalls comfortably cover 100 to 300 guests over a several-hour event, depending on food and drink service. For exact headcount math tied to event length, use how many porta potties do I need as a planning reference before booking.
Does the trailer need a power hookup?
Most trailers run interior lighting and pumps off a standard outlet or generator; ask Fontana Porta Pros what your specific unit requires. Larger sites sometimes add a temporary power pole or light tower rental for evening events.
Can I rent a 4 stall trailer for a construction site?
Yes, though most crews start with a standard porta potty rental and upgrade to a trailer for supervisors or long-term jobs. Pair it with a handwashing station rental to stay ahead of general sanitation expectations.
What if I only need it for a weekend?
Weekend rentals are common for Fontana weddings and family events; pricing sits separate from weekly rates, so ask for a weekend quote directly rather than dividing the weekly rate.
Is delivery included in the trailer price?
No, delivery is billed separately from the unit rental. Confirm the delivery fee and any distance charge when you request a quote from Fontana Porta Pros.
