How Many Units Do You Need?

Set the headcount and the length of the job and this works the count out with the same ratios we use on the phone. It updates as you change it.

Open Mon–Sat 4am–4pm

The ratio changes between a working crew and a crowd.

How many workers on site?

Count everyone who will be on site on a normal day.

The Ratios

Where These Numbers Come From

Job sites follow the crew: about one unit for every ten workers, serviced weekly, which is the practical reading of the sanitation guidance under 29 CFR 1926.51. Events follow the guest count and the clock: one unit per fifty guests over a few hours, scaled up as the event runs longer. Alcohol adds roughly a fifth again. Festivals are sized for the surge between acts rather than the average, so the ratio tightens further.

Two things are constant. One handwashing station for every four toilets, and more than that wherever food is served. And at least one accessible unit, with another for every twenty standard units after that — on firm, level ground with a clear approach, because an accessible unit that cannot be reached is not accessible.

Questions

About the Estimator

Is the estimate a quote?
No — it is a starting point built from the same ratios we use on the phone. The quote comes from the call, where we can factor in the site, the season and how long the units are staying.
Why does alcohol change the number?
Because it changes how often people use a restroom, by a surprising margin. Adding roughly twenty per cent of capacity at a bar event is the difference between a line and no line.
Do I really need an accessible unit?
For a public or permitted event, almost certainly — and permit conditions sometimes set a minimum. Even where it is not required, one accessible unit on firm ground with a clear approach is the single easiest thing you can do to make a site usable.
The calculator gave me a bigger count than I expected; now what?
Call and say so. More capacity is not automatically better, and we would rather talk an order down to what the site actually needs than sell you units that sit unused.
