How Porta Potty Finder Is Built
Everything below is what we actually do. If it changes, this page changes first.
Where the data comes from
Our team reads each listed company's own website and records which unit types it says it rents — standard, flushing, ADA, restroom trailer, hand-wash station, shower trailer — along with the exact sentence the claim came from and the date we read it. We do not call for quotes and we do not estimate. The current edition covers 1,977 independent operators.
What counts
Independently owned portable sanitation companies in the United States. We exclude national carriers such as United Site Services and United Rentals, brokers who resell your booking, and the multi-state marketing networks that run a page per town off one website — here is who, and why.
What we measure, and what we don't
We measure unit coverage: which kinds of unit each company actually rents. That is the field that decides whether a company can take your job, and it is the one no other directory collects. A blank against a company means its website does not name that unit, not that it can't supply one, so every figure on this site is printed next to the number of sites it was read from.
The clearest illustration is the standard unit. It reads 48%, which is lower than the restroom trailer, and that is plainly not true of the industry: practically every yard runs standard units. What they don't do is write "standard portable toilet" on a page already headed porta potty rental, while a trailer gets named because it is a premium product that sells. The measure rewards being written down, so treat it as how findable a unit is rather than how common. It earns its keep on the rare units, where being written down and being available line up.
We do not publish prices. Rates in this industry are quoted per job rather than posted, so where we show money it is stated as a typical industry range, never as a measured median. For a real number, two quotes from the independent yards on your town page beat any national average.
How companies are ranked
Town pages order companies by an Index Score out of 100: review volume 30, rating 25, unit coverage 30, reachability 15. Unit coverage is weighted by rarity, because nearly every yard has a standard unit and few have a restroom trailer. Placement cannot be bought, and no listed company pays anything. A company moves up by earning reviews or by listing the units it actually rents.
Known limitations
- A company that does not describe its units online is under-counted here, even if its yard is well stocked. Claiming the listing fixes that.
- Service areas are estimated as a 25-mile radius from the company's address, not confirmed with the owner. Always check they cover you.
- Websites go stale. Every figure carries the date it was read, and coverage is thinner in rural states where fewer operators keep a detailed website.
