A 4 stall restroom trailer covers most weddings, corporate builds and weekend festivals in Westminster without a line forming. Rental runs from single-day events to multi-week job sites, with pricing shaped by how long you keep it and what options you add. Westminster Porta Pros sets up, levels and services the unit so you never touch a valve.
Trailer pricing depends heavily on duration and finish level. A day rate for a restroom trailer generally falls between $175 and $2,500, while a full week runs $150 to $1,650 and a multi-day event package can land between $2,499 and $3,899. Weekend bookings, common for Saturday weddings, typically fall between $900 and $3,000. Westminster Porta Pros builds the quote around headcount, hookup access and how far the unit sits from a water source. For a broader breakdown by duration, see restroom trailer rental cost or compare against a luxury restroom trailer if your event calls for a nicer finish.

If a 4 stall unit is more than your guest count needs, a 2 stall restroom trailer may fit smaller gatherings, and an 8 stall restroom trailer handles bigger crowds without doubling up on trailers.
Four private stalls, sinks and climate control are standard, built for steady traffic across a full event day or a busy job site week. Westminster job sites still fall under OSHA 1926.51(c), which sets toilet counts by crew size, so a trailer this size comfortably serves crews under the 20-worker threshold before a second unit becomes worth adding. If handwashing has to meet 29 CFR 1910.141(d)(2), the sinks need soap and towels or a dryer, not just sanitizer, and Westminster Porta Pros stocks units that way. Compare against the base standard porta potty rental or step up to a deluxe flushable porta potty if a full trailer is more than the site needs. For accessibility, ADA Standards 213.2 requires at least one accessible unit where portable toilets are clustered, and we can pair an ADA accessible porta potty alongside the trailer to cover that requirement without retrofitting the whole unit.
Placement comes down to ground stability and hookup distance, not just open space. ADA Standards 302.1 calls for a stable, firm, slip-resistant surface, which rules out soft turf or loose gravel without matting. We check clearance the same way we do for roll-off dumpster rental, since a delivery truck needs roughly 60 feet of straight approach to back in safely. Westminster events near Broomfield, 5.6 miles north, or Federal Heights, 3.9 miles southeast, often need the trailer delivered a day early for leveling and water hookup. If your venue sits in the public right of way, placement needs confirming with the City of Westminster before delivery. Our porta potty placement guide covers ground and slope basics, and the temporary power pole page is worth a look if the trailer's climate control needs power beyond what's on site.
It depends on where the trailer sits. Placement in the public right of way needs confirming with the City of Westminster, and we don't guess at local rules. Check our porta potty permit requirements page, or ask us directly when you request a quote.
It depends on guest count and event length. Our how many porta potties do I need guide walks through the math, but a 4 stall trailer generally covers moderate weddings and single-day corporate events well.
Yes, if the crew size and OSHA 1926.51(c) ratios support it. Many Westminster contractors pair a trailer with standard units anyway, especially for construction site services running multiple weeks.
Yes. Westminster Porta Pros delivers, levels, connects and services the unit through the rental period, the same standard we apply to portable restroom rental and event restroom rental bookings.
Weekly rates cost more in total but less per day than repeated daily bookings. Compare the numbers on porta potty rental per day against monthly porta potty rental before you commit to a term.
