OSHA 1926.51 Table D-1

Construction Site Toilet Rules

How many job site toilets OSHA requires, and how many Sean Rental Works recommends.

20 workers or fewer

1 toilet

OSHA Table D-1 sets one toilet as the legal minimum for a crew of 20 or fewer.

More than 20 workers

1 seat + 1 urinal per 40

Above 20 workers, OSHA requires one toilet seat and one urinal for every 40 workers.

200 workers or more

1 seat + 1 urinal per 50

Our recommendation

1 unit per 10 workers

That fits a 40-hour week with weekly service. Bigger crews or longer hours? Add a service day.

Weekly service included

Each visit pumps out the tank, cleans the unit, restocks toilet paper and refills hand sanitizer. Extra visits can be added.

28-day billing

Construction units bill on a 28-day cycle, not a calendar month. Billing renews until you call for pickup. Pickup is not automatic.

Site setup

Ask for a free lockable hasp. Keep the truck within about 15 feet. On wet clay lots, a gravel or plywood pad keeps the unit level.
