Chengde Mobile Toilet Size Atlas

There is currently no publicly available specific size atlas for mobile toilets in Chengde, but common specifications can be categorized into three types based on usage: single-unit, multi-unit combinations, and special functional areas, with specific size ranges as follows:

Single-Unit Mobile Toilets
The external dimensions of single-unit mobile toilets typically range from 1.2 meters to 1.5 meters in length, 1 meter to 1.2 meters in width, and 2.2 meters to 2.5 meters in height. The internal clear dimensions are close to the external dimensions, commonly ranging from 1.2 meters to 1.5 meters in length, 1.0 meters to 1.2 meters in width, and 2.2 meters to 2.5 meters in height. These toilets are suitable for scenarios with low foot traffic, such as temporary events and small construction sites, with their compact design facilitating rapid deployment and mobility. The internal space must meet basic usage requirements, including passage space for door opening and installation positions for squat or sit toilets, while the height design takes into account adult standing and ventilation needs.

Multi-Unit Combination Mobile Toilets
The overall length of multi-unit combination mobile toilets can be extended according to demand, for example, a three-unit combination toilet can have a total length of 3.6 meters to 4.5 meters. A double-toilet unit occupies an area of approximately 3 square meters to 4 square meters; for three or more toilet units, each additional toilet unit increases the usable area by approximately 1.5 square meters to 2 square meters, with the overall length mostly ranging from 3 meters to 6 meters and the width typically being 1.5 meters to 2.5 meters. These toilets are suitable for scenarios with high foot traffic, such as tourist attractions and large event venues, achieving flexible combinations through modular design to meet usage requirements while facilitating transportation and installation. The width design must consider passage space and equipment layout to ensure convenience for multiple users simultaneously.

Special Functional Areas
Special functional areas include accessible toilet stalls and baby care rooms/third restrooms. The internal clear dimensions of accessible toilet stalls must not be less than 1.8 meters by 1.4 meters, meeting the requirements for wheelchair turning space and auxiliary equipment installation to ensure the safety of disabled users. Baby care rooms/third restrooms generally have an area of not less than 4 square meters, equipped with facilities such as baby changing tables and safety seats, with space design taking into account the joint usage needs of adults and infants to provide a private and comfortable environment. These functional areas reflect the humanized design of mobile toilets and are suitable for scenarios with high requirements for public service facilities.
