Nantong Mobile Toilet Size Atlas

The common size specifications of mobile toilets in Nantong are as follows, covering different types to meet diverse needs:

I. Common Sizes Classified by the Number of Users

1. Single-Person Volume Type

   • The basic size is 1.2 meters (length) × 0.8 meters (width) × 2.3 meters (height), with an internal space of approximately 1.5 cubic meters. This design is suitable for scenarios with low pedestrian density, such as small events or temporary construction sites, balancing functionality and space utilization through a compact layout.
   • The finished single-person basic model has dimensions of 1.1 meters × 1.1 meters × 2.3 meters, with the width increased by 0.3 meters to enhance user comfort while maintaining the same height to ensure ventilation and lighting effects.

2. Double-Person Volume Type

   • The size is 1.8 meters × 0.8 meters × 2.3 meters, enabling two people to use it simultaneously by extending the length. It is suitable for medium-scale events or public places, such as food festivals and exhibitions, significantly reducing waiting times.
   • The finished double-person shared model has its length extended to 2.5 meters, with a width of 1.1 meters and a height of 2.3 meters, optimizing space allocation by increasing the length to avoid a cramped feeling during use.

3. Barrier-Free Design Type

   • Designed for the needs of special populations, the size is approximately 1.5 meters × 1.0 meters × 2.4 meters, with increased width and height to provide sufficient space for wheelchair access and turning, complying with barrier-free facility standards.
   • The finished barrier-free mobile toilet has its size further optimized to 1.5 meters × 1.8 meters × 2.4 meters, with the width extended to 1.8 meters to accommodate accompanying assistants, reflecting a human-centered design concept.

II. Special Sizes Classified by Portability

• Small Portable Foldable Type: The size can be reduced to 1 meter × 1 meter × 2 meters, enabling rapid transportation and deployment through a foldable structure. It is suitable for remote areas, emergency rescue, or temporary events, with a lightweight design (usually less than 100 kilograms) facilitating manual handling.

III. Core Principles of Size Design

1. Functionality First: All sizes must meet basic usage requirements, such as a door width of ≥0.8 meters to ensure wheelchair access and an internal clear height of ≥2 meters to avoid a sense of oppression.
2. Modular Expansion: Double-person and barrier-free models achieve capacity enhancement through length or width extension, rather than simply stacking single units, to control costs and floor space.
3. Standardized Compatibility: Finished models have a unified height of 2.3-2.4 meters, facilitating connection with existing sewage and power supply systems and reducing on-site modification difficulties.

In practical applications, the size type should be comprehensively selected based on site conditions, pedestrian flow, and user characteristics. For example, the double-person shared model is recommended for short-term high-traffic scenarios like food festivals, while long-term public facilities are advised to be equipped with barrier-free models to enhance social inclusivity.
