Porta Potty With a Sink vs. a Separate Hand-Washing Station
Both give guests running water and soap. The right choice depends on how many units you need and whether food is served.

Is a porta potty with a sink better than a hand-washing station?
A porta potty with a built-in sink is better for a single-unit party, because guests wash up inside and you only rent one item. A separate hand-washing station is better for 3 or more toilets, food service and crews, because several people can wash at once without waiting for a stall.
| Deluxe unit with sink | Separate station | |
|---|---|---|
| Best for | 1–2 unit parties | 3+ units, food, crews |
| Crowd flow | Wash inside the stall | Wash without a stall |
| Cost for 1 toilet | Usually lower | Usually higher |
| Cost for 4+ toilets | Higher | Usually lower |
When is a hand-washing station required?
A hand-washing station is required where workers handle paint, coatings or other harmful materials under OSHA 29 CFR 1926.51(f), and on farms under OSHA 1928.110. Temporary food service also needs hand washing under Tennessee health rules.
Source: OSHA 29 CFR 1926.51.
How many hand-washing stations do I need?
Plan 1 hand-washing station for every 10 toilets at an event, with at least 1 near every food area. A job site with 10 to 20 workers needs 1 two-sided station between weekly services. A two-sided station lets two people wash at once.
| Setup | Stations |
|---|---|
| Backyard party, 1 toilet | 0 (choose a sink unit) |
| Event, 5 toilets, buffet | 1 at the food line |
| Festival, 20 toilets | 2, plus 1 per food area |
| Crew of 15 | 1 two-sided station |
What does a hand-washing station need on site?
A hand-washing station needs a level spot about 3 by 2.5 feet, close to the toilets or food line, that the service truck can reach. It needs no power or plumbing. Fresh water, soap and paper towels are refilled at each service visit.
