How many do you actually need?

Three questions decide it: how many people, for how long, and whether there is alcohol.

The usual event starting point

Roughly one unit per 50 guests for a four-hour event — assuming no alcohol and a steady arrival pattern.

Alcohol changes the maths

Bar events typically need a third to a half more capacity. One extra unit is cheaper than the queue.

Job sites work differently

The common industry starting point is one unit per 10 workers with weekly servicing. Your OSHA obligation is set by the standard, not by us.

Count the peak, not the average

A ceremony, a race finish or a shift break empties the whole site into the queue at once.

We will size it with you

Tell us the job and we will do the count out loud, including the parts we are unsure about.
