Toilets for Your Event

Porta Potty Calculator

Porta Potty Calculator

Imagine hosting the most anticipated outdoor wedding of the year, with 200 guests ready to celebrate. Or perhaps you’re at the helm of a construction project, coordinating a team of 75 dedicated workers.
In both scenarios, there’s one detail that can make or break the day – the availability of adequate portable restroom facilities. At Star Porta Potty Rental, we’re well aware that a miscalculation can lead to either an inflated budget or a line of uncomfortable guests or workers.
That’s why we’ve developed our porta-potty calculator. Our tool is designed to help you determine the right number of porta-potties you’ll need, ensuring comfort and convenience for everyone.

How to Use the Calculator

Our porta-potty calculator is user-friendly. Simply input the number of people attending your event or the number of workers on your site, along with the duration of the event or workday. The calculator will then provide an estimate of the number of porta-potties you’ll need.

Please note that these are estimates and the actual number may vary depending on the specific circumstances of your event or site. The number of porta potties needed increases with the number of attendees and the length of the event.

Determining Your Porta Potty Needs For Construction Sites

At Star Porta Potty Rental, we know that the number of porta potties needed for a construction site or an event is crucial for maintaining comfort and hygiene.
The key factors to consider are the number of individuals who will be using the facilities and the duration of their use.
For construction sites and similar industrial settings, a good rule of thumb is one porta potty for every 10 workers during a standard 40-hour work week. However, this ratio can be adjusted based on specific commercial needs.
In line with the OSHA Sanitation Standard for Construction, we recommend the following:

  • For 1 to 20 workers: A minimum of 1 toilet
  • For 20 to 190 workers: At least 1 toilet seat and 1 urinal for every 40 workers
  • For 200 or more workers: 1 toilet seat and 1 urinal per 50 workers

Maintaining Cleanliness and Hygiene

Maintaining the cleanliness and hygiene of porta potties is of utmost importance, especially for long-duration events and job sites. At Star Porta Potty Rental, we prioritize regular and thorough servicing of our units.
We understand that dirty or insufficient restrooms can leave a lasting negative impression and even affect productivity on a job site. Therefore, we encourage careful calculation of your needs. Providing the right number of well-serviced facilities ensures that restroom breaks are comfortable, convenient, and — unless you aim to impress your guests with a luxury restroom experience — perfectly unremarkable.
Our porta potty calculator is a helpful tool in the planning process, but it’s always best to consult with a sanitation expert for a more accurate estimate. At Star Porta Potty Rental, we’re here to help. Contact us today for a personalized quote.

Factors to Consider Porta Potties For Events

Number of People and Duration: The main factors to consider are the number of people who will use the restrooms and the number of hours you’ll need them. The standard ratio for construction sites and other industrial settings is one porta potty per 10 workers in a 40-hour work week.
Alcohol Consumption: If alcohol is being served at your event, you may need to increase the number of porta potties by 10% to 20%.
Availability of Permanent Restrooms: If there are permanent restroom facilities available at the site, this will reduce the need for portable restrooms.
Gender Considerations: If your construction project includes women workers, it’s recommended to provide separate facilities for them.
ADA Requirements: Ensure you meet the Americans with Disabilities Act requirements. There should be at least one handicap-accessible restroom and one handicap-accessible restroom for every 20 portable restrooms (a ratio of 5 percent).
