Next to the food
A sink at the restroom block is not much use to someone handling food fifty yards away. Put stations where the handling happens.
Add-on units
Foot-pump sinks that pair with any restroom order and need nothing from the site — no plumbing, no power. Wherever food is being prepared or served, this is the unit that turns a restroom setup into a complete one.

Everything worth knowing before you pick up the phone.
Planning
A sink at the restroom block is not much use to someone handling food fifty yards away. Put stations where the handling happens.
The other half of the job. A restroom without handwashing nearby is the complaint people actually remember.
One station serving a queue runs dry. For busy events plan on more units and more frequent restocking rather than one heavily used sink.
Servicing
A handwash station fails quietly. The water runs out, or the soap does, and nobody tells you. Restocking is the part of the service visit that actually matters on these units, so it is the part we check first.
Questions
Neither. The station carries its own fresh water and collects waste in a sealed tank underneath, and the pump is foot-operated. It only needs firm ground and a route for the delivery truck.
It tracks traffic rather than headcount alone. Food handling areas need their own, restroom blocks need their own, and a busy event is better served by several stations than one that runs dry. Tell us the layout and we will suggest a number.
It depends entirely on use. A quiet job site can run a week between refills, a busy food event can empty a tank in a day. For high-traffic setups we schedule more frequent visits rather than hoping it holds.
Tell us where the food and the restrooms are going and we will work out how many stations that layout needs.
