Mobile Toilet Composition Drawing Dimensions

The dimensions of mobile toilet composition drawings vary depending on the type, with common specifications as follows:

I. External Dimensions Classified by the Number of Stalls

1. Single-Stall Mobile Toilets: The external dimensions typically range from 1.2 to 1.5 meters in length, 1.0 to 1.2 meters in width, and 2.2 to 2.5 meters in height. The standard single-person model on the market has dimensions of 110 cm in length, 110 cm in width, and 230 cm in height; the mini single-person model, designed for compact spaces, measures 100 cm in length, 100 cm in width, and 220 cm in height.
2. Multi-Stall Combined Mobile Toilets: A two-stall unit can reach lengths of 2.4 to 3.0 meters while maintaining a width of 1.0 to 1.2 meters; container-type mobile public toilets can exceed 6 meters in length and 2.5 meters in width. For example, a mobile toilet with four squatting stalls and a handwashing area has a total length of 6 meters; the double-person model measures 180 cm in length, 110 cm in width, and 230 cm in height.
3. Barrier-Free Mobile Toilets: These have larger external dimensions, typically measuring 180 cm in length, 150 cm in width, and 240 cm in height. The internal clear width must be at least 1.5 meters, and the clear depth must be at least 1.8 meters to accommodate wheelchair turning space.

II. Dimensional Specifications for Internal Functional Areas

1. Toilet Area: The clear width should not be less than 0.85 meters, with an ideal range of 0.9 to 1.0 meters; the clear depth must ensure 1.2 to 1.5 meters to provide sufficient space for users. The door width should be no less than 0.6 meters for easy access. The recommended dimensions for a standard single stall are 0.9 × 1.2 meters, balancing space utilization and comfort.
2. Handwashing Area: In multi-stall combined toilets, the handwashing area is usually integrated with the toilet area. For example, in a mobile toilet with four squatting stalls and one handwashing area, the handwashing area needs to be equipped with a sink, mirror, and storage space, but specific dimensions lack a unified standard and must be adjusted according to actual needs.

III. Explanation of Design Differences
The dimensions of mobile toilets are significantly influenced by materials, structure, and functional requirements. For instance, barrier-free toilets require additional space for wheelchair passage, resulting in larger external dimensions; mini models achieve compact designs by compressing non-essential spaces (such as reducing storage areas). In actual drawings, dimension markings must consider details such as wall thickness and pipe layout to ensure that functional areas do not interfere with each other and comply with ergonomic principles.
