A portable toilet is a self-contained sanitation unit designed for temporary use in outdoor settings, such as construction sites, festivals, and camping areas. These toilets are typically made of durable plastic and are equipped with a waste holding tank, ensuring that waste is contained and can be disposed of properly later. Portable toilets come in various designs, including standard units, accessible models for individuals with disabilities, and luxury options with additional features. They are often serviced regularly to maintain hygiene and cleanliness, making them a practical solution for events and locations without permanent restroom facilities.
