Dimensions and Specifications of Portable Toilets

The dimensions and specifications of portable toilets vary depending on the type and usage scenario. Common specifications are as follows:

Single-unit Portable Toilets
Typically, the length ranges from 1.2 to 1.5 meters, the width from 1.0 to 1.2 meters, and the height from 2.2 to 2.5 meters, suitable for construction sites, small events, etc. Among them, the standard model has dimensions of 110cm in length, 110cm in width, and 230cm in height; the mini model is more compact, with dimensions of 100cm in length, 100cm in width, and 220cm in height, ideal for small exhibitions or commercial streets with high foot traffic. These toilets are designed with a focus on space utilization, ensuring that the toilet stall width is no less than 0.9 meters to meet basic usage needs.

Double-unit Portable Toilets
The length ranges from 2.4 to 3.0 meters, the width from 1.2 to 1.5 meters, and the height from 2.2 to 2.5 meters, commonly found at large events or tourist attractions. The double-occupancy model typically has dimensions of 180cm in length, 110cm in width, and 230cm in height, allowing two people to use it simultaneously, improving usage efficiency. These toilets require sufficient passage space to avoid congestion during peak hours.

Multi-functional Portable Toilets
The length can reach 3.0 to 4.5 meters, the width 2.0 to 2.5 meters, and the height 2.5 to 3.0 meters, suitable for high-end events or long-term fixed locations. They are equipped with more comprehensive internal facilities, possibly including independent sinks, storage cabinets, etc., and their dimensions need to be adjusted according to functional requirements. Design should balance practicality and aesthetics, meeting the regulatory requirements for long-term usage scenarios.

Barrier-free Portable Toilets
The standard dimensions are 180cm in length, 150cm in width, and 240cm in height, specifically designed for individuals with disabilities. Their key features include reserved space for wheelchair rotation (with a diameter of no less than 1.5 meters), door width sufficient for wheelchair access (usually no less than 0.9 meters), and equipped with handrails, low-position sinks, and other barrier-free facilities. These toilets are often placed in public areas such as large parks and scenic spot entrances, reflecting humanistic care.

Design Considerations and Specifications
All types must comply with the 'Urban Public Toilet Design Standard' (CJJ 14-2016), such as ensuring that the toilet stall width is no less than 0.9 meters and the sink height is recommended to be between 0.8 and 0.9 meters. Additionally, transportation should consider road height restrictions (usually not exceeding 2.5 meters) and width restrictions, and installation should ensure a flat ground surface to avoid tilting that affects structural stability.
