Event planning is a complex process, and many organizers often overlook the importance of porta-potty rentals. While it may sound surprising, the humble portable toilet can make or break your event’s success. Not enough, and you risk long lines and frustrated guests. Too many, and you’re wasting resources.
Aside from long wait times, not meeting event porta-potty requirements can have significant sanitary consequences. Guests may have to use the restroom outside the designated facilities, in bushes, around hidden corners, or even on the sides of buildings. This makes your event much less sanitary—the potential spread of disease, contamination, and ecological impact skyrocket.
If you lack the proper facilities and your guests have to use the restroom in public, they may be fined for public indecency. This can tarnish guest experience and, in turn, harm your event’s reputation. A portable toilet calculator can help you avoid these instances and ensure your event flows smoothly.
Consider the entire duration of your event from start to finish. Longer events like multi-day festivals or conferences will require more portable toilets to ensure the comfort of your guests. For example, a three-day music festival might necessitate twice as many toilets as a one-day affair.
The nature of your event also guides your restroom needs. Large-scale events like music festivals or outdoor markets typically require more portable toilets due to their expansive layouts and diverse attractions. Smaller events, such as corporate meetings or workshops, typically have fewer restroom demands.
The size and layout of your event will also determine how many restrooms you need. Large venues with multiple stages or focal points will need toilets scattered strategically to reduce congestion. At construction sites, you’ll need to position toilets throughout the job site to ensure easy access for your employees.
The number of attendees directly impacts the number of portable toilets you need for your event. In fact, the attendee count and the number of porta potties per person scale proportionately. Whether your event has 100 guests or 10,000, you need to accurately estimate attendance in advance to ensure you can provide sanitary facilities for everyone.
Event staff and vendors may require their own facilities. Placing these restrooms away from guest areas allows both convenience and privacy. Be sure to consider the needs of groups like food vendors, security staff, performers, and more.
Events featuring food and beverages—especially alcohol—have increased restroom usage, so you’ll need to anticipate demand to avoid long lines and ensure cleanliness. A general rule of thumb is to add 15-20% more portable toilets to your event if you’re serving food and drink.
Identify peak restroom usage time, such as after meals, in between music sets, or before your event’s conclusion. You’ll need to adjust the placement and number of toilets at your event to account for these restroom surges.
Various regulations imposed by organizations like the EPA, OSHA, ADA, and your local municipality will dictate minimum restroom requirements. For example, 1 in 20 restrooms are required to be ADA-compliant to ensure accessibility. OSHA and the EPA require certain ratios and placements as well.
Depending on your event, you may require a number of different restroom options. For example, an upscale event might require a luxury portable restroom with running water and attendants, while a job site may require a hoistable or low-ceiling portable restroom. In any case, these diverse needs will determine how many toilets you require for your space.
