Restroom trailers in Philadelphia are available for rent to whomever needs one. However, they differ when it comes to the price. The rental cost is usually determined by the number and style of units ordered. The total cost of a rental can also be affected by the length of lease and the schedule of when it will be rented. Take note that the rental fees for restroom trailers in Philadelphia are slightly higher during weekends and holidays and for shorter rental durations. A restroom trailer that has many toilets can cost around $1,000 to $5,000 per weekend. The cost may still vary depending on the size of the trailer. Restroom trailers are commonly used in weddings and high-end events where you may want to make your guests feel like they are using a permanent restroom rather than just a stall.
