Most jobs need a standard unit: one stall about 44 inches wide, 48 deep and 91 tall, with a 60 to 70 gallon tank.1 Add a hand wash station where people eat or handle chemicals, an ADA unit wherever the public goes, and sink, flushing or restroom trailer units when guests expect more. Standard units were the type our provider network placed most: 43,268 in the past two years.2

Placed: units delivered by the Detritus provider network, October 2024 through October 2026.2 Flushing includes 120 with a sink. Sizes span two manufacturers' spec sheets per type;13456 other makers run close but not exact, so ask for the spec sheet if a doorway or pad is tight.
Which type do I need?
Answer a few questions and we'll suggest a type, plus the extras that usually go with it. This picks the types, not the count. For the count, see how many portable toilets you need.
Every type
One molded plastic stall with a seat over a holding tank, a urinal, a vent stack and a toilet paper holder. The default for crews and most events.1
The standard shell plus a foot-pump sink and fresh and gray water tanks. Often called deluxe or upgraded. For sites that serve food or can't fit a hand wash station beside every unit.
A foot pump rinses the bowl. Fresh-water units use a separate clean tank, with a sink in the system; recirculating units reuse filtered water from the waste tank. Neither needs a hookup.3
A larger, ground-level stall with a wide door, grab bars and room to turn a wheelchair. Smaller tanks, so it fills faster than a standard unit.4
Narrow enough for a standard door and a hoist, with lifting points for a crane, so crews on upper floors don't walk down. Standard units can also go up in a rated frame or sling.5
A standard unit bolted to a single or double trailer that a pickup tows to the next work zone: roadwork, pipelines, utilities, farms and any crew that moves.
Foot-pump sinks, soap, towels and fresh and gray water tanks. Put one beside any unit without a sink, and wherever food is served.6
Real flushing toilets, sinks, lighting and often climate control, in separate stalls. What most people mean by a luxury or VIP porta potty.9
Private hot-water stalls with a changing area and lighting, for long jobs, crews living on site and disaster response. Our provider network supplies them. Share your headcount and dates and we'll check your area.9
Units set in a spill tray, for contracts or permits that require secondary containment (14 placed).2 Fresh water and waste holding tanks for trailers and site offices without a hookup.
ADA compliance. The 2010 ADA Standards call for a 60 inch turning circle inside an accessible toilet room. Not every unit sold as wheelchair accessible meets it,7 so ask for the spec sheet if your permit or contract requires compliance. When ADA units are required, and how many: ADA units on our OSHA page.
Washing and showers on job sites. 29 CFR 1926.51(f) requires washing facilities where crews apply paints, coatings, herbicides or insecticides, or handle other harmful contaminants, and one shower for every 10 employees of each sex where showers are required.8
Restroom trailer layouts
Stall count depends on how many people use the trailer at the same time, not total headcount. We also place 1, 7 and 9 stall trailers; ask for those by layout.
Before you order, read what a restroom trailer needs on site. For weddings and festivals, see event restroom planning.
| Layout | Placed2 | Bar |
|---|---|---|
| 2 stall | 293 | |
| 3 stall | 73 | |
| 3 stall with an ADA stall | 14 | |
| 4 stall | 192 | |
| 5 stall | 14 | |
| 6 stall | 15 | |
| 8 stall | 12 | |
| 10 stall | 21 |
Send the site address, headcount, duration and the types you have in mind. Pricing depends on market, unit type, rental length and service frequency, so each site is quoted on its own.
