A portable toilet cabin, also known as a portable restroom or portable toilet, is a self-contained unit designed to provide temporary sanitation facilities in areas where permanent restroom facilities are unavailable or impractical. These units are commonly used at construction sites, outdoor events, festivals, parks, and other locations where people may need access to restroom facilities.

Portable toilet cabins typically consist of a small cabin or trailer that contains a toilet, a sink, and sometimes a shower. They may be equipped with a holding tank for waste or connected to a sewer or septic system. They are designed to be easily transported and can be set up quickly and easily.

The cabins are available in different sizes and configurations to accommodate different usage requirements. Some units are designed for single use, while others can accommodate multiple users at once. They are typically made of lightweight, durable materials such as plastic or fiberglass and are designed to withstand outdoor weather conditions.
