A 4 stall restroom trailer runs from around 175 dollars a day to well over 1,650 dollars for a full week, depending on finish level and event length. It suits crowds between 100 and 300 people, big enough for a wedding at a Round Rock venue or a multi-day construction job. Round Rock Porta Pros builds each rental around your headcount and hookup access.
Four stalls work well for gatherings in the 150 to 300 person range, or crews running 30 to 60 workers across a shift. If your event is smaller, a 2 stall restroom trailer covers it for less. Bigger festivals or fairgrounds usually need an 8 stall restroom trailer instead. For construction sites, OSHA 1926.51(c)(1) sets the baseline: one toilet facility for 20 workers or fewer, then a seat and urinal per 40 workers as crews grow past that. A 4 stall unit often satisfies that ratio for a mid-size Round Rock crew without doubling up on standard units. Not sure where you land? The porta potty calculator guide walks through headcount math, and our construction site services page covers full jobsite setups including fencing and dumpsters.
Pricing depends on rental length, trailer finish, and delivery distance. Here's how the bands break down:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2,500 |
| Weekend | 900 | 2,000 | 3,000 |
| Week | 150 | 1,397 | 1,650 |
| Event (flat rate) | 2,499 | 3,500 | 3,899 |
Delivery adds a separate fee, generally 100 to 500 dollars depending on distance and access. If you're hosting near Hutto, about 8.1 miles east, or Brushy Creek, roughly 6.9 miles west, tell us the drop site up front so we can quote delivery accurately. For a broader cost breakdown across trailer types, see restroom trailer rental cost. If your event is smaller-scale, standard portable units may fit your budget better; check porta potty rental cost or the monthly porta potty rental page for longer jobs.
Not automatically. Standard 4 stall trailers are built for general use, and accessibility depends on the specific unit. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent must be accessible, with a minimum of one. ADA Standards section 404.2.3 sets a 32 inch minimum clear door opening, and section 304.3.1 calls for a 60 inch turning circle inside the accessible stall. If your event or jobsite needs guaranteed compliance, ask about pairing your trailer with a dedicated ADA accessible porta potty, or review our ADA restroom requirements guide before booking. Ramp slope, where used, follows section 405.2 at no steeper than 1:12.
Water and handwashing matter too. Under OSHA 1926.51(a)(1), an adequate supply of potable water must be on site, and 29 CFR 1910.141(d)2) requires soap and towels or a hand-drying device at wash stations, not just sanitizer. Trailers we deliver in Round Rock come plumbed for this. If you need standalone handwashing instead, see handwashing station rental or portable sink rental.
Weddings, golf tournaments, and county fairs around Round Rock often pair a 4 stall trailer with a luxury restroom trailer for VIP areas. Browse wedding restroom rental, golf tournament restrooms, or county fair restrooms for setup examples. For general event planning, the event restroom rental hub covers timing and headcount together.
Plan for roughly 60 feet of straight clearance behind the delivery truck, the same clearance needed for roll-off drops. Flat, stable ground matters most. ADA Standards section 302.1 requires floor and ground surfaces be stable, firm and slip resistant, which also protects the trailer's leveling jacks on soft Round Rock lots.
Yes. Weekend rates run from 900 to 3,000 dollars depending on trailer finish and add-ons. It's a common choice for weddings and two-day festivals where a full week isn't needed. Ask about pairing with temporary fence rental for crowd flow.
Most run on standard household power or a generator; specific amperage depends on trailer features like AC and lighting. Confirm your unit's requirements when booking, especially for remote sites without existing hookups near Round Rock job locations.
Stall count and footprint. A 4 stall suits mid-size events and crews; an 8 stall restroom trailer handles larger festivals or fairgrounds. Both come in standard or upgraded finishes.
Placement in the public right of way needs confirming with the city. For placement on private property, check our porta potty permit requirements guide or contact us directly through request a quote before delivery day.
