How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably cover crews and crowds in the low hundreds, depending on hours and turnover. For construction, OSHA 1926.51(c) sets the baseline: one toilet facility for 20 workers or fewer, then a second seat and urinal once you cross 20 workers. A 4 stall unit generally slots between the standard porta potty rental count and a full 8 stall restroom trailer. For events, use our how many porta potties do I need guide or check the festival restroom rental page for crowd math. Weddings, golf tournament restrooms, and county fair restrooms in Antioch all lean on this size when a single 2 stall unit falls short.

What Does a 4 Stall Restroom Trailer Cost in Antioch?
Trailer pricing depends heavily on duration and features. Below is what fits the measured range for restroom trailers generally; a 4 stall unit sits toward the lower-to-mid end of these bands compared to larger multi-stall trailers.
| Duration | Typical Range |
|---|---|
| Day | $175 - $2,500 |
| Week | $150 - $1,650 |
| Event | $2,499 - $3,899 |
A weekend rental for a trailer this size often lands in the $900 to $3,000 range, so weekday jobs and multi-day events price very differently. Compare against our restroom trailer rental cost page for the full breakdown, or look at the 2 stall restroom trailer if your guest count is smaller. Delivery is billed separately and typically runs $100 to $500 depending on distance and access. Antioch job sites near Brentwood, about 6.8 miles southeast, and Oakley, 8.7 miles east, fall well within our normal service radius, so delivery fees stay on the lower end of that band.
Does a 4 Stall Restroom Trailer Meet ADA and Site Requirements?
Standard 4 stall trailers are not automatically ADA compliant; you need a separate accessible unit or an ADA-equipped trailer stall. ADA Standards section 213.2 requires that where single-user portable units are clustered, at least 5 percent, and never fewer than one, must be accessible. ADA Standards section 404.2.3 sets minimum clear door width at 32 inches, and section 403.5.1 requires a 36 inch clear route to the unit. If your Antioch site needs a compliant stall, pair the trailer with our ADA accessible porta potty or ask about an luxury restroom trailer built with a wider stall. Placement also matters: OSHA 1926.56(a) sets illumination minimums for construction areas, so trailers used after dark on job sites need adequate lighting nearby, which we can pair with a light tower rental. For power, most 4 stall trailers run off standard outlets, but larger setups may need a temporary power pole. Water and waste hookups follow the same footprint rules used across our construction site services work throughout Antioch.

Frequently asked questions
What is the difference between a 4 stall and an 8 stall restroom trailer?
A 4 stall trailer fits mid-size events and job sites, roughly 100 to 300 people depending on hours. An 8 stall restroom trailer doubles the capacity for larger festivals or bigger crews. If you're between sizes, our how many porta potties do I need guide walks through the math.
Does the trailer need a water and power hookup?
Yes, most 4 stall trailers need a nearby water source and standard electrical outlet to run lights, fans and the flush system. If your Antioch site lacks hookups, ask about self-contained options or add a temporary power pole to the order.
Can I rent a 4 stall restroom trailer for a wedding?
Yes, this size is common for wedding restroom rental in Antioch, especially outdoor venues without existing restroom access. Many couples pair it with a deluxe flushable porta potty unit as backup for larger guest lists.
How far in advance should I book?
Book as early as you can, especially for weekend events, since trailer availability tightens around peak wedding and festival season. For urgent needs, check emergency porta potty rental for faster turnaround options.
