How many toilets are needed for 100 people?
For 100 people at a 4-hour event, you need between 2 and 3 portable toilets. If the event includes alcoholic drinks, increase to 3-4 units. For 6-hour events plan for 3-4 toilets; for 8+ hours, 4 to 6 units.
This is the direct answer for the most common case. Use the calculator for your exact guest count, or check the full table below. In Guadalajara, Luvory Luxury Toilets rents and installs these units with same-day delivery.

The base formula is: 1 sanitary unit per 50-75 people for a 4-hour event. For events with alcoholic drinks, we recommend 1 per 35-50 people.

Reference table by guest count and duration
| Guests | 4 hours | 6 hours | 8+ hours |
|---|---|---|---|
| 50 | 1-2 | 2-3 | 3-4 |
| 100 | 2-3 | 3-4 | 4-6 |
| 200 | 4-5 | 5-7 | 7-10 |
| 500 | 8-10 | 12-15 | 15-20 |
| 1,000+ | 15-20 | 20-30 | 30+ |
Factors that increase the need
Alcohol
If your event includes an open bar or alcoholic drinks, increase the quantity by 20-30%. Alcohol consumption significantly increases usage frequency.
Weather
At outdoor events in hot weather, guests drink more fluids. This can increase toilet needs by 15-20%.
Gender ratio
Events with a higher proportion of women require more units, since average usage time is longer. Our trailers are designed with this in mind, offering more stalls in the women's section.
Event type
- Formal wedding: premium ratio (1:40)
- Music festival: high ratio (1:50) with continuous maintenance
- Corporate event: standard ratio (1:60)
- Construction site: regulated ratio (1:10 per 8-hour shift)

- Plan for maintenance: for events longer than 4 hours, hire cleaning service during the event
- Strategic placement: distribute toilets across multiple points of the venue
How many people does one toilet serve?
The base industry rule: 1 portable toilet serves 50 people at a 4-hour event. For longer events or ones with alcohol, that capacity drops:
- 4 hours, no alcohol: 1 toilet per 50-75 people
- 4 hours, with alcohol: 1 toilet per 35-50 people
- 8 hours: 1 toilet per 25-35 people
For luxury weddings, Luvory recommends a ratio of 1 unit per 40 people to guarantee comfort with no lines.
How many toilets are needed per person at a company or a construction site?
The ratio depends on the type of worksite:
- Offices and companies: Mexico's NOM-031-STPS standard sets 1 toilet up to 15 employees, 2 up to 25, 3 up to 50, and 1 more per 30 additional employees.
- Construction sites: the industry standard is 1 portable toilet per 10 workers per 8-hour shift. If the site runs more than one shift, each shift needs its own calculation — the calculator below already does this for you.
| Employees (office) | Toilets (NOM-031-STPS) | Workers (construction site) | Toilets (1 8h shift) |
|---|---|---|---|
| Up to 15 | 1 toilet | 10 | 1 toilet |
| 16 to 25 | 2 toilets | 20 | 2 toilets |
| 26 to 50 | 3 toilets | 50 | 5 toilets |
| Every 30 additional | 1 more toilet | Every 10 additional | 1 more toilet |
