How many handwashing sink stations do you need?

Calculating how many handwashing sink stations you need to rent for a special event or construction job site is usually determined by the number of standard toilets present.


The following recommendation is based on our regular dual basin handwashing sink station:

A min of 1 handwashing station for every 3 toilets

For example, if you rent 60 toilets, we recommend you rent 20 handwashing stations. Remember that handwashing usage can increase if food and beverages are served, or if the event has higher than normal levels of dirt or mud.


The following law requirement is based on Section 1527 in Title 8 of the California Code of Regulations:

A min of 1 handwashing station for every 20 employees

However, if there are fewer than 5 employees working at the job site, and only 1 portable toilet is provided, then the required handwashing facility may be located inside of the toilet. In this instance, you would need to rent our Deluxe toilet.
