Porta Potty Units & How Many You Need
What each unit is for, what it needs on site, and roughly how many you'll want.
Standard Porta Potty
The one most jobs and casual events need. It has a vent, a non-slip floor, a door that locks and shows when it's in use, and a hand sanitizer dispenser. We restock the paper and sanitizer every time it's serviced.
- Works for most job sites and outdoor events.
- Can be moved on a hand truck, so most gates and side yards are fine.
- Add a handwashing station if food is being served.
Deluxe Porta Potty
The same size as a standard unit, with a better inside. Depending on the model, that usually means a hand sink with fresh water, a flushing bowl, a mirror and better light. Still no water line, drain or power needed.
- Good for weddings, parties and client-facing sites.
- Goes anywhere a standard unit can.
- Worth it when guests, not work crews, are using it.
ADA Accessible Unit
A larger unit with a door that opens outward, grab bars inside and enough floor space to turn a wheelchair. Events open to the public usually need at least one under the ADA Standards for Accessible Design.
- Grab bars placed to help with transferring.
- Also handy as a family or changing stall.
- Needs a firm, level path to reach it, not just a level spot.
Handwashing Station
A freestanding sink with its own fresh-water tank and a tank for the used water, usually worked with a foot pump. Health rules for food events generally require one wherever food is served or prepared.
- No plumbing or hookup needed.
- Place one near the food as well as one by the restrooms.
- Tell us your headcount so there's enough water for the day.
Restroom Trailer
Closest to an indoor restroom, with flushing toilets, running sinks, mirrors and lights. A trailer needs a level spot, room to tow it into place and a power supply, so check with your venue first.
- Usually considered for larger weddings and corporate events.
- Needs a level pad, towing access and power.
- Call to ask about availability for your date.
How many do you need for an event?
Enter your numbers for an estimate, or use the table below. Both use the same common planning figures, and the assumptions are shown with the result. The porta potty calculator has worked examples and the full method.
- 1 unit per 50 guests for 4 hours, plus 25% for each extra 2 hours.
- 20% more when there's a bar. A common planning allowance, not a rule.
- Public events: the 2010 ADA Standards call for at least 5% of clustered portable toilets, and no fewer than one, to be accessible.
- Serving food? Add handwashing stations near the food and the restrooms.
