What is an 8 stall restroom trailer?
An 8 stall restroom trailer is the largest single towable restroom unit in normal rental circulation: eight private stalls split across two entrances, each side with its own vanity run, flushing toilets, running water, lighting and dedicated climate control. Most builds put four toilets on the women's side and a mix of toilets and urinals on the men's.
The jump from four stations to eight is not just capacity. Tank volume roughly doubles, the tow rating moves into commercial territory, and the unit stops fitting anywhere that a pickup could park. If your site is a garden or a rowhouse block, the 4 station trailer or the 2 station trailer is the realistic option. The restroom trailer overview has all three side by side.
8 stall restroom trailer dimensions and specs
Typical manufacturer specification ranges for an eight-station towable restroom trailer:
| Spec | Typical figure |
|---|---|
| Body length | 24 to 32 ft |
| Body width | 8.5 ft |
| Overall length with tow vehicle | 50 to 60 ft |
| Waste tank | 800 to 1,250 gal |
| Fresh water tank | 200 to 400 gal |
| Dry weight | 9,000 to 14,000 lb |
| Power | Three 120 V, 20 amp circuits, or a generator |
| Stalls | 8 across 2 entrances |
Water weighs 8.34 pounds per gallon, so a full 1,250 gallon waste tank adds more than 10,400 pounds on top of the dry weight. That single figure explains most of the logistics: the unit cannot be nudged once it is loaded, the pad has to hold well over ten tons, and the vacuum truck has to be able to reach the outlet without crossing turf it will rut.
What does an 8 stall restroom trailer cost in Philadelphia?
| Rental period | Typical range |
|---|---|
| Per day | $700 to $1,400 |
| Weekend | $2,000 to $3,000 |
| Per week | $2,400 to $4,000 |
| Per month | $4,500 to $7,500 |
Market ranges reviewed July 2026, not a quote. Delivery on a timed one-day event drop typically runs $100 to $500, weekly delivery $50 to $150, and each service visit $30 to $220 because the tank volume sits at the top of the range. Generator hire is quoted separately. Full line-item detail is on restroom trailer rental cost, and if the budget is the deciding factor, porta potty rental cost shows what the same capacity costs in standard units.
Where an 8 station trailer actually fits in Philadelphia
An eight-station trailer needs roughly 60 feet of straight approach, a turning area, and a pad that will not sink. In this city that narrows the list quickly, which is worth knowing before you plan around one.
Sites that take it comfortably:
- The asphalt lots around Lincoln Financial Field, Citizens Bank Park and the Wells Fargo Center, where tailgates, race staging and sponsor activations all run
- Large open ground and service drives in Fairmount Park for daytime festivals and regatta weekends
- Penn's Landing and waterfront event decks with truck access from the road side
- Long-duration hospital and university construction sites in University City, alongside a mobile office trailer and storage containers
- Suburban fields and fairgrounds out toward Doylestown and Bensalem
Sites that do not take it: any rowhouse block, most Center City side streets, Manayunk's grades, and soft turf after rain. For those, split the load across two smaller trailers or run a bank of portable restrooms with a handwashing station. The placement guide covers what the driver checks on arrival.
How many guests does an 8 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 once alcohol is served. Eight stalls therefore covers roughly 400 guests dry, or about 330 at a bar event, before you add anything else.
Above that, the answer is a second trailer or a mixed setup rather than a bigger single unit, because eight stations is where the towable format tops out. Large Philadelphia events typically run one trailer for guests or VIP areas and standard units on the perimeter, which is how festival restroom rental, concert restroom rental, marathon and road race restrooms and county fair restrooms are usually built. Work the total on how many porta potties do I need.
Power, permits and service on a unit this size
An eight-station trailer commonly asks for three separate 120 volt, 20 amp circuits. NFPA 70, the National Electrical Code, rates each of those at roughly 2,400 watts, and two air conditioning units plus pumps and lighting will not run off one household outlet. Article 590.6 of the same code requires GFCI protection on temporary receptacles. Where site power is not available, we plan a generator, a temporary power pole or both, and light tower rental covers the walking route after dark.
Philadelphia handles portable toilet and holding tank applications through the Department of Public Health under its infectious waste program rather than through a streets or transportation department, which is not where most event producers expect to file. Build the lead time in. See porta potty permit requirements. ANSI/PSAI Z4.3, the American National Standard for nonsewered waste-disposal systems, sets weekly service as the baseline, and a 400 person event on an eight-station unit almost always needs a mid-event pump-out booked in advance. Accessible provision is separate again, because the 2010 ADA Standards cap ramp slope at 1:12 in section 405.2, so an ADA ground-level unit goes beside the trailer. ADA restroom requirements has the counts.
How do you book an 8 stall trailer in Philadelphia?
Send the exact site address with cross streets, the load-in and load-out times, the expected peak headcount, the power available, and a note on the surface the trailer will stand on. Photographs of the approach help more than anything else on a job this size, because the failure mode is always access rather than the unit itself.
Use the quote form or the contact page, and book early for May, June, September and October when Philadelphia's event calendar takes most of the large stock.
