OSHA 1926.51(c)

Table D-1

20 or fewer workers: 1 toilet
20 or more: 1 seat + 1 urinal per 40 workers
200 or more: 1 seat + 1 urinal per 50 workers

Confirm with your safety officer.
One unit =
1 + 1

A standard porta potty has 1 toilet seat and 1 urinal inside.
Our pick
1 per 10

With weekly service, plan 1 unit per 10 workers so the unit stays usable all week.
