What is a 2 stall restroom trailer?
A 2 stall restroom trailer is the smallest towable restroom with real plumbing: two private rooms, each with its own exterior door, a flushing toilet, a sink with running water, a mirror, a light and a lock. Builders usually configure one room as a men's side with a urinal beside the toilet, which lifts throughput past what a two-door unit looks like it should manage.
It is a different machine from a portable toilet, not a bigger one. A standard porta potty holds waste in a 60 to 70 gallon tank under the seat. A two-station trailer keeps fresh water and waste in separate tanks, so the flush puts clean water between the user and everything below, and that is the whole reason it does not develop a smell over a weekend. The restroom trailer pillar puts every size in one table.
2 stall restroom trailer dimensions and specs
Typical manufacturer specification ranges for a two-station towable restroom trailer:
| Spec | Typical figure |
|---|---|
| Body length | 14 to 16 ft |
| Body width | 7 to 8 ft |
| Overall length with tongue | 18 to 20 ft |
| Waste tank | 200 to 300 gal |
| Fresh water tank | 40 to 100 gal |
| Dry weight | 2,800 to 4,000 lb |
| Power | One 120 V, 20 amp circuit |
| Rooms | 2, each with a separate door |
Under NFPA 70, the National Electrical Code, a 20 amp branch circuit supplies roughly 2,400 watts. That runs the lights, the water pump, and either the heater or the air conditioner, but not both together on a July afternoon. Water weighs 8.34 pounds per gallon, so a full 300 gallon waste tank puts over 2,500 pounds on the frame, which is what decides whether the unit can be repositioned mid-rental or has to be pumped where it stands.
Where a 2 station trailer fits in Philadelphia when nothing bigger will
This is the size that solves Philadelphia. At 7 to 8 feet wide and 16 feet long the unit takes one parking space instead of three, and it can be backed into places an eight-station trailer will never reach.
Placements that work here for a two-station and rarely work for anything larger:
- Rear courts and shared alleys behind South Philadelphia and Bella Vista rowhouses
- Narrow driveways and side yards in Roxborough, Mount Airy and Overbrook
- Chestnut Hill and Germantown gardens reached through a single gate
- Park paths and lawn edges in Fairmount Park where a wider unit would tear the turf
- Film base camps on one-way Center City blocks, alongside the film set restroom setup
- Rowhouse gut renovations where the trailer replaces a site toilet for the finish trades, covered on home renovation porta potty rental
Access still decides everything. If the block is parked solid on both sides the driver cannot set the unit, and the single most common cause of a failed delivery in this city is a car in the drop spot. The placement guide lists what to hold clear and for how long.
What does a 2 stall restroom trailer cost in Philadelphia?
| Rental period | Typical range |
|---|---|
| Per day | $175 to $425 |
| Weekend | $700 to $1,250 |
| Per week | $850 to $1,600 |
| Per month | $1,700 to $2,900 |
Market ranges reviewed July 2026, not a quote. Delivery in a weekly context typically adds $50 to $150 and each additional service $30 to $220. The trailer cost breakdown itemises every line, and porta potty rental cost is the comparison worth running first, because two deluxe flush units cover the same headcount for a third of the money if the finish does not matter.
How many guests does a 2 stall trailer cover?
Portable Sanitation Association International event guidance is one restroom per 50 to 100 guests over four hours, with 15 to 20 percent added when alcohol is served. Two stations therefore suits a ceremony or reception of roughly 100 people, or about 80 once a bar opens.
Past that, step up to a 4 station trailer or keep the trailer for guests and put standard units back of house for staff and crew. Work your own number on how many porta potties do I need. For a small wedding the layout advice on wedding restroom rental applies at any size, and event restroom rental covers the wider planning. A portable sink beside the door keeps both vanities free, which on a two-station unit is the difference between a queue and no queue.
Permits, power and water on a Philadelphia site
Philadelphia issues portable toilet and holding tank approvals through the Department of Public Health under its infectious waste program, which is not the streets department process most contractors expect to file with. On private property that application does not come into it at all. Full detail is on porta potty permit requirements.
On site the unit needs a 120 volt, 20 amp GFCI-protected outlet within about 100 feet, a hose bib or a tank fill, and a pad flat enough to level on. Article 590.6 of NFPA 70 requires that GFCI protection on temporary receptacles, so an older exterior outlet on a rowhouse may not qualify. Where there is no power, a temporary power pole or a generator solves it, and light tower rental handles night events. Waste leaves by vacuum truck the same way a holding tank does.
2 stall shower trailers and higher-finish builds
Two-station shower trailers run on the same chassis, usually built as two private shower rooms or one shower plus one restroom, and they are covered on the shower trailer page. Higher-finish two-station units with solid-surface vanities and wood-look floors sit on luxury restroom trailers and price roughly 25 to 60 percent above the table above.
Accessibility is a separate build. The 2010 ADA Standards cap ramp slope at 1:12 in section 405.2, so a trailer floor 36 inches up needs 36 feet of ramp, which does not fit on a Philadelphia sidewalk. The working answer here is an ADA ground-level unit set next to the trailer, with a 36 inch clear route to the door under section 403.5.1. ADA restroom requirements has the full spec.
How do you book a 2 stall trailer in Philadelphia?
Servicing a two-station unit means pumping the waste tank, refilling fresh water, restocking paper and soap, and wiping down. ANSI/PSAI Z4.3, the American National Standard for nonsewered waste-disposal systems, sets weekly service as the baseline for a standing unit, and event trailers usually get a service on the way in and on the way out instead.
Before you call, know the address with cross streets, the surface the trailer lands on, whether there is an outlet and a hose within reach, and whether the spot is private property or public curb. The rental checklist has the rest. Send it through the quote form or the contact page. Same-day needs go through emergency porta potty rental, and between December and March ask whether the unit is winterised, because porta potties in winter is what catches people out here. We deliver across the city and out to Conshohocken, Haverford and the rest of the areas we serve around Philadelphia.
