What is a standard porta potty?
A standard porta potty is a single occupancy portable restroom with a holding tank, a seat, a urinal, a toilet paper holder and a hand sanitiser dispenser. It needs no water or power connection. Weekly servicing is standard on job sites, and one unit per 10 workers is the practical ratio. Call 1-833-520-0680 for local pricing.
Who is this unit for?
Construction and job site crew facilities- Outdoor parties, races and block parties

How many standard units does a site need?
On a construction site the legal floor comes from OSHA 29 CFR 1926.51: one facility for up to 20 workers, then one toilet seat and one urinal per 40 workers up to 199. Almost every contractor orders above that, because one unit per 10 workers is what keeps a unit usable across a week of standard servicing.
For events the working ratio is one unit per 50 guests for up to four hours, with more units as the duration and headcount climb.
What is the difference between this and a deluxe unit?
Water. A standard unit has a chemical holding tank and a hand sanitiser dispenser. A deluxe flushable unit adds a foot operated flush, a fresh water sink and a mirror.
For a working crew the standard unit is the right tool and the deluxe is an unnecessary cost. For a wedding or a corporate event where guests will use it, the flushable unit is usually worth the difference.
How long does a unit stay usable between services?
Roughly 100 uses, which is the practical capacity of a 60 to 70 gallon tank. That maps to about 10 workers over a five day week, which is where the one per 10 ratio comes from.
Heat shortens it. High temperatures increase both fluid intake and odor, so sites that are fine on weekly service in March often need twice weekly service in July.
What makes a good position?
Firm, level ground the service truck can reach within about 25 feet. Beyond that, think about the walk: a unit placed where nobody wants to go gets ignored, and a unit placed in the middle of the work area gets knocked.
On job sites the usual answer is just inside the site entrance. It keeps the service truck off the active area and gives the crew a short, obvious walk.

Fittings vary slightly between manufacturers. Your provider confirms what the specific unit includes and how often it will be serviced.
Where should the unit go?
Set the unit on firm, level ground with the door opening away from the main thoroughfare. The service truck needs to get within about 25 feet, which is the constraint that decides most placements on a tight site.
A standard unit occupies roughly 4 by 4 feet with the door opening outward, so allow about 5 by 5 feet of clear space. The service truck needs to get within about 25 feet of the unit, which is the constraint that decides most placement questions.

Standard Porta Potty questions
How many people can one standard unit serve?
On a job site, about 10 workers between weekly services. At an event, roughly 50 guests for up to 4 hours. Both figures assume the unit is serviced on schedule.
How many uses does the tank hold?
Around 100 uses at a typical 60 to 70 gallon tank size. Past that the unit becomes unpleasant and needs servicing regardless of the schedule.
Does it need water or electricity?
No. A standard unit is completely self contained with a chemical holding tank, which is why it works on remote and undeveloped sites.
Is there a sink inside?
A standard unit has a hand sanitiser dispenser rather than a sink. If you need running water, order a hand wash station alongside, or step up to a deluxe flushable unit.
How much space does it need?
The unit is about 4 by 4 feet, so allow 5 by 5 feet of clear space for the door to swing, plus truck access within about 25 feet.
Can it be used in winter?
Yes. Providers add antifreeze to the holding tank in freezing conditions. Keep a cleared path so the service truck can still reach the unit.
