At present, no unified standard specifically for mobile toilets in Hepu factory buildings has been retrieved. However, the dimensions of mobile toilets are usually designed according to their type, function, and usage scenarios. The common types and specifications are as follows:

1. Single-Stall Mobile Public Toilets Single-stall mobile toilets are suitable for scenarios with limited space or temporary needs. The common size ranges are as follows:

• Floor Area: Approximately 1.2㎡ to 1.8㎡, with internal clear dimensions typically being 1.2m to 1.5m in length × 1.0m to 1.2m in width, and a height of 2.2m to 2.5m.
• Common Market Models: The regular model has dimensions of 110cm in length, 110cm in width, and 230cm in height; the mini model has dimensions of 100cm in length, 100cm in width, and 220cm in height. These toilets are compact in structure, suitable for single-person use, and are equipped with basic facilities such as a squat or sit toilet and a sink.

2. Multi-Stall Mobile Public Toilets Multi-stall mobile toilets are suitable for areas with a high density of people, such as factory buildings and construction sites. The common specifications are as follows:

• Double-Stall: The floor area is approximately 3㎡ to 4㎡, with an overall length of about 1.8m to 2.5m and a width of 1.5m to 2m. The common double-person model on the market has dimensions of 180cm in length, 110cm in width, and 230cm in height.
• Triple-Stall and Above: For each additional stall, the usable area increases by approximately 1.5㎡ to 2㎡, with the overall length mostly ranging from 3m to 6m and the width from 1.5m to 2.5m. These toilets need to be designed with consideration for the width of the aisles and the layout of the stalls according to actual needs to ensure convenience of use.

3. Accessible Stalls Accessible stalls need to meet the requirements for wheelchair passage and turning, with stricter dimensional requirements:

• Internal Clear Dimensions: Must not be less than 1.8m × 1.4m. An accessible ramp with a width of ≥0.8m and a slope of ≤1:12 must be provided at the entrance.
• Adapted Dimensions: The common dimensions of accessible mobile toilets are 180cm in length, 150cm in width, and 240cm in height, with sufficient internal space reserved for wheelchair turning and equipped with facilities such as handrails and emergency call devices.

4. Nursing Rooms/Third Restrooms Nursing rooms or third restrooms need to cater to the needs of both adults and children, with higher requirements for area and facilities:

• Area: Generally not less than 4㎡, with a clear width of ≥1.5m to ensure operating space.
• Facility Configuration: They need to include an infant changing table, a child's toilet, a safety seat, etc. In some scenarios, an adult's toilet and a sink also need to be provided to ensure functional completeness.

The above specifications are common design parameters for mobile toilets. When making an actual selection, it is necessary to comprehensively evaluate based on the size of the factory staff, usage frequency, and site conditions.
