Short, practical guides from Ernest on OSHA rules, placement, billing, winter servicing and event planning around Easton and the Lehigh Valley.
A restroom trailer gives wedding guests flushing toilets, running water and lights, but needs a hose, a dedicated 110V outlet and a level 20-foot spot. For 150 guests, a 3-stall trailer is an estimated $1,800–$2,800, while 4 deluxe and accessible units plus a sink run about $1,300–$1,875.

A graduation party needs 1 porta potty per 50 guests, plus at least 1 extra if you serve alcohol, so 80 guests over 5 hours with drinks need 3 units. Book 2 to 4 weeks ahead for May and June, when party weekends fill first.

A porta potty keeps working in winter when the waste tank gets a brine or antifreeze mix once temperatures drop below 32°F. Keep a shoveled path to the unit, keep it within 15 feet of a plowed surface, and hold weekly service even in January.

Monthly porta potty rentals are billed every 28 days, not by calendar month, which works out to 13 billing cycles in a year. Each cycle renews on its own until you call (610) 229-3331 to schedule pickup before the cycle ends.

Put a porta potty on flat, level ground within about 15 feet of pavement or gravel our truck can drive on. Keep it about 20 feet from food and at least 10 feet from doors, leave a clear service path, and mark the exact spot before delivery day.

OSHA 29 CFR 1926.51(c) requires at least 1 toilet for 20 or fewer workers, and 1 toilet seat plus 1 urinal per 40 workers above that. That is the legal floor; we suggest about 1 job site toilet per 10 workers with weekly service so units stay usable all week.
