Count your toilets
Start with one toilet per 50 people for up to 4 hours. Add one per 100 people if the day runs 4 to 8 hours, and one more per 100 if drinks are served. Round every step up.
Toilet chart by crowd size
100 people need 2 toilets for a short event, 3 for a long day and 4 for a long day with drinks. 300 people need 6, 9 and 12. Restroom trailers run about one stall per 50 guests.
| People | Up to 4 hrs | 4–8 hrs | 4–8 hrs + drinks | Trailer stalls |
|---|---|---|---|---|
| 40 | 1 | 2 | 3 | 1 |
| 60 | 2 | 3 | 4 | 2 |
| 100 | 2 | 3 | 4 | 2 |
| 150 | 3 | 5 | 7 | 3 |
| 200 | 4 | 6 | 8 | 4 |
| 300 | 6 | 9 | 12 | 6 |
| 500 | 10 | 15 | 20 | 10 |
| 800 | 16 | 24 | 32 | 16 |
Worked example: a 5K with 400 runners
- Runners all line up before the start, so count the start line: 400 ÷ 50 = 8 toilets.
- Add 1 accessible unit at the start cluster.
- Put 1–2 more at the finish and water stops.
- Women's lines run longer — if you can, split the start cluster so more units face the women's side.
How many toilets does a work crew need?
OSHA 29 CFR 1926.51(c) Table D-1 requires one toilet for up to 20 workers, one seat and one urinal per 40 workers from 20 to 199, and one per 50 above 200. In practice one unit keeps about 10 workers comfortable for a 40-hour week with weekly service.
Worked example: an 8-person roofing crew, 45 hours a week. OSHA floor: 1. Comfort count: 8 ÷ 10 = 1 unit with weekly service — add a second visit in a hot August week. Text: OSHA 1926.51; farms follow OSHA 1928.110.
Counting questions
There will be 120 people. What do you recommend?
For a 4-hour event, plan 3 standard units (1 per 50 guests, rounded up). Add a fourth if drinks are served, and make one of them accessible if the event is public.
How many toilets for a 400-runner 5K?
Runners all go at once, before the start. Plan about 1 toilet per 50 runners near the start line — 8 for 400 — plus 1 accessible unit and 1 at the finish area.
How many people can one unit handle over a whole weekend?
About 50 guests for a single 4-hour stretch. Across a full weekend of use, add a mid-event cleaning or a second unit.
Is one toilet enough for 60 people?
For a short party, one toilet plus a wash station handles about 60 guests if the line moves. For an all-day event, add a second unit.
