Count guests, then check how long the party runs. Here is the simple method Sean Rental Works uses in Murfreesboro.
1 unit per 50 guests
Always round up. A 3-hour party with 120 guests needs 3 standard porta potties.
1 unit per 35 guests
Round up again. A 6-hour backyard party with 150 guests needs 5 standard units.
1 unit per 25 guests
All-day festivals and overnight camping fill tanks faster, so plan more units per guest.
Add 1 unit for every 4
Guests drinking beer or wine use the restroom more often. Round up: 6 units becomes 8.
2010 ADA Standards §213.2 call for at least 5% of portable units in a cluster to be accessible, minimum one, where toilets serve the public.
1 station per 4 units
Plan hand wash stations especially when food is served. Each station has two foot-pump basins, soap and paper towels.
200 ÷ 35 rounds up to 6 units. Alcohol adds 2, so 8 standard. Add 1 wheelchair-accessible unit and 2 hand wash stations.
