What comes inside a 4 stall restroom trailer?
Four private stalls, running water, and interior lighting are the baseline. Most units in this class include separate flush toilets rather than the holding-tank chemical style you'd find in a standard porta potty rental, and sinks with real soap and towel dispensing to meet 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device at any washing station. Tustin Porta Pros sets these up for weddings, corporate events and longer construction jobs where crews want something closer to an actual restroom. If you need something between a standard unit and a full trailer, compare the deluxe flushable porta potty option, or step up further with a luxury restroom trailer for events with a higher guest count. Every trailer needs a stable, level pad. ADA Standards section 302.1 calls for surfaces that are stable, firm and slip resistant, which matters on gravel lots or unfinished job sites around Tustin. For crews comparing footprints, the 2 stall restroom trailer and 8 stall restroom trailer sit on either side of this size, and the restroom trailer rental page breaks down all three.
How much does a 4 stall restroom trailer cost in Tustin?
| duration | low | typical | high |
|---|---|---|---|
| day | $175 | $800 | $2,500 |

| event | $2,499 | $3,500 | $3,899 |
Weekend rentals in Tustin typically run somewhere between 900 and 3,000 dollars depending on trailer size and add-ons like generator power or attendant service. A single-day rental makes sense for a small gathering; a full weekend or event package fits a wedding or multi-day festival better. For the full cost breakdown across trailer sizes, see restroom trailer rental cost, and for smaller single-unit pricing check porta potty rental cost or porta potty rental per day. Jobs running a month or longer usually do better with a monthly porta potty rental quote instead, since trailer day rates aren't built for that timeline.
Where can a 4 stall restroom trailer be placed on site?
It needs a level, accessible spot with enough clearance for delivery and hookup. Tustin sits about 3.1 miles south of North Tustin and 12.6 miles south of Placentia, and delivery routes through either direction are straightforward for our drivers. If your event needs an accessible unit alongside the trailer, ADA Standards section 213.2 requires at least 5 percent of clustered single-user toilets to be accessible, with a minimum of one, and our ADA accessible porta potty units satisfy that alongside a trailer setup. Ramped entries must not exceed a 1:12 running slope per ADA Standards section 405.2, and doorways need a minimum 32 inch clear opening under section 404.2.3. Placement questions come up on every job, so read our porta potty placement guide before delivery day, and check porta potty permit requirements since placement in the public right of way in Tustin needs confirming directly with the city. Construction sites also need to hit OSHA 1926.51(c) toilet ratios separate from trailer count, so pair the trailer with enough standard units per crew size using our how many porta potties do I need guide.
How many people can a 4 stall trailer handle in one day?
There's no fixed number, but four stalls comfortably serve a wedding of 100 to 150 guests over an evening, or a mixed crew on a construction site services job across an 8 to 10 hour shift. Larger guest counts should step up to the 8 stall restroom trailer.
Does the trailer need a power hookup?
Most units run lighting, pumps and water heating off standard power, and Tustin Porta Pros can supply a generator if your site doesn't have one. Ask about pairing with a temporary power pole or a light tower rental for evening events.
Can I rent a 4 stall trailer for just a weekend wedding?
Yes. Weekend rates fall between roughly 900 and 3,000 dollars depending on trailer finish. See wedding restroom rental for setup details specific to ceremonies and receptions.
What's the difference between this and a standard porta potty setup?
A 4 stall trailer offers flush toilets, sinks and climate control in one enclosed unit, versus separate porta john rental units with holding tanks. Trailers cost more but feel closer to indoor plumbing.
Do I need a permit to place a trailer in Tustin?
Possibly, depending on where it sits relative to the street. Confirm placement rules directly with the City of Tustin before delivery, and review dumpster permit requirements if you're also renting a roll-off for the same job.
