I. Basic Dimension Ranges

1. Single-Stall Mobile Public Toilets

   • Regular Model: Occupies an area of approximately 1.2㎡ to 1.8㎡, with internal clear dimensions typically ranging from 1.2m to 1.5m in length × 1.0m to 1.2m in width, and a height of 2.2m to 2.5m. Commonly available sizes in the market are 110cm in length, 110cm in width, and 230cm in height; the mini model measures 100cm in length, 100cm in width, and 220cm in height.
   • Construction Site Single Stall: Typically has a width of 1.0m to 1.2m, a depth of 1.0m to 1.5m, and a height of 2.0m to 2.5m to accommodate temporary use needs.

2. Multi-Stall Mobile Public Toilets

   • Three Stalls and Above: For each additional stall, an additional 1.5㎡ to 2㎡ of usable area is required, with the overall length and width adjusted according to the number of stalls. The width of a double-squat mobile toilet at construction sites is approximately 2.0m to 2.4m.

II. Functional Partition Dimensions

1. Barrier-Free Stalls

   • Must comply with the 'Barrier-Free Design Code', with internal clear dimensions not less than 1.8m × 1.4m. The entrance must be equipped with a barrier-free ramp wider than 0.8m, and space must be reserved inside the stall for wheelchair rotation. Mobile toilets adapted for barrier-free needs are larger, commonly measuring 180cm in length, 150cm in width, and 240cm in height; barrier-free toilets at construction sites must have a width of ≥1.5m and a depth of ≥1.8m.

2. Baby Care Rooms/Third Restrooms

   • Generally have an area of not less than 4㎡, and must include facilities such as baby changing tables and children's toilets, with a clear width of ≥1.5m to ensure operational space. Such functional partitions have high space requirements to meet the needs of special populations.

III. Basis for Dimension Selection

The dimension design of mobile toilets must comprehensively consider usage scenarios, functional requirements, and regulatory standards. For example, single stalls are suitable for areas with low foot traffic, while multi-stalls are suitable for scenic spots, construction sites, etc.; barrier-free stalls and baby care rooms must be configured according to the proportion of the service population to ensure compliance and practicality. When making actual purchases, it is recommended to confirm dimension details with suppliers based on specific needs to avoid affecting the user experience due to insufficient space.
