For a three-day backyard wedding with 100 guests, food and an open bar, deluxe units are worth the extra cost. Guests notice the difference between a standard portable toilet and a flushing unit with a sink and mirror, especially over multiple days. A standard unit has a non-flushing holding tank with deodorizer, while a deluxe unit provides a more restroom-like experience with a flushing bowl and running water sink. The comfort matters for a wedding where guests dress up and socialize.
Follow the event planning guideline of about one unit per 50 to 75 people for a four-hour event, but add units for alcohol, longer duration and a mixed-gender crowd. For 100 guests over three days, plan for more than the minimum. Include at least one ADA-compliant unit if you cluster the toilets together, as the ADA Standards require accessible units in clusters.
Service frequency increases with use: a standard unit needs weekly service normally, but for a wedding with heavy use, plan for service during or after the event. Deluxe units with flushing and sinks may need more frequent servicing due to their fresh water tanks and gray water disposal. The cost difference comes from the unit type, rental duration, service visits and any add-ons like handwash stations or lighting. Deluxe units cost more to rent and service, but for a special event, they improve guest comfort significantly.
