A 4 stall restroom trailer runs 3 to 4 units side by side, split by gender or kept unisex, and fits weddings, block parties and mid-size job sites in Southfield. Weekly rental for a standard trailer of this class falls between 150 and 1650 dollars depending on features. Southfield Porta Pros builds the layout around your headcount.
The right count depends on guest volume and hours, not just event type. A 4 stall unit generally covers 100 to 300 guests over a single day, which is why it sits between the 2 stall restroom trailer and the 8 stall restroom trailer in most quotes we write for Southfield clients. Construction crews sizing sanitation for a job site should check OSHA 1926.51(c), which sets ratios for standard toilet facilities: one for 20 workers or fewer, then one seat and one urinal per 40 workers above that. If your crew runs closer to 20 people over multiple weeks, a bank of standard porta potty rental units may pencil out cheaper than a trailer. For events with a fixed guest list, use our how many porta potties do I need guide, or compare against the 2 stall restroom trailer if the crowd runs under 100. We also handle event restroom rental planning for weddings and festivals across Southfield where a 4 stall setup is the middle option most hosts land on.
Every 4 stall trailer from Southfield Porta Pros comes with flushing toilets, sinks with running water, and interior lighting, which sets it apart from a standard porta potty rental or even a deluxe flushable porta potty. Handwashing setups meet 29 CFR 1910.141(d)(2), which requires soap and a towel or drying device on site; sanitizer alone does not satisfy this standard, which matters if your event is also staffed and subject to inspection. If the site needs a fully accessible unit instead of or alongside the trailer, ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, and we pair that with our ADA accessible porta potty line. Delivery into most of Southfield adds a delivery fee, and weekend trailer rentals for events like weddings or golf outings run in a separate premium tier from weekday work, so ask us to break out delivery separately when you request a quote. For jobs needing hot water for cleanup, not just handwashing, ask about pairing with a shower trailer rental.
A 4 stall trailer needs level, stable ground and clear approach room for the delivery truck. ADA Standards section 302.1 requires the ground surface to be stable, firm and slip resistant if the unit is meant to be accessible, and section 405.2 caps ramp slope at 1:12 where a ramp is used. Placement in the public right of way in Southfield needs confirming with the city before delivery day; we do not guess at that rule and neither should you. See our porta potty placement guide for setback basics, and our porta potty permit requirements page before you plan curb placement. Southfield sits inside a cluster of towns we service regularly. Oak Park is 4.9 miles east, Birmingham is 7.2 miles northeast, and Redford is 7.6 miles south, so delivery routing rarely adds meaningful drive time to your quote. If your venue also needs temporary fence rental or a light tower rental for evening events, we can bundle those into the same delivery run.
Weekly rates for trailers in this class span 150 to 1650 dollars, and single day rentals range from 175 up past 2500 depending on trim level and add-ons. Weekend event pricing runs separately, often 900 to 3000 dollars. See restroom trailer rental cost for a full breakdown by duration.
Right of way placement needs confirming with the city before your delivery date. Driveways and private lots typically avoid that question entirely. Check our porta potty permit requirements page, or ask us directly when you request a quote.
Yes, though most crews under 20 workers do fine with standard porta potty rental units per OSHA 1926.51(c). Larger crews or multi-week construction site services jobs sometimes prefer a trailer for morale and cleanliness.
Four standard units cost less upfront but lack sinks with running water and interior lighting. A trailer suits events and staffed sites better; see portable restroom rental for side by side options.
Stall count scales with guest volume, not event length. Choose the 8 stall restroom trailer once headcount clears roughly 300 guests in a single day; below that, four stalls generally keeps lines short.
