Dimensions of Public Mobile Toilets in Tianjin
The dimensions of public mobile toilets in Tianjin vary depending on the type and functional requirements, with common specifications as follows:
Single-unit mobile toilets are a basic type, with common external dimensions such as approximately 1.2 meters × 1.2 meters × 2.3 meters and 1.5 meters × 1.5 meters × 2.5 meters. Some opinions also point out that the external length of common single-stall mobile toilets ranges from 1.2 meters to 1.5 meters, the width is approximately 1.0 meter to 1.2 meters, and the height is mostly within the range of 2.0 meters to 2.3 meters. The minimum dimensions of a basic single-person independent mobile toilet are approximately 1.2m × 1.0m × 2.2m (length × width × height). This size can meet basic single-person usage needs and has a relatively compact space; the conventional dimensions are approximately 1.5m × 1.2m × 2.3m (length × width × height), which ensures single-person usage comfort while also facilitating installation and movement.
For multi-stall row-type mobile toilets, the dimensions of each stall are similar to those of single-unit toilets. The overall length increases proportionally with the number of stalls, while the width and height remain generally consistent. Taking a double-stall (two-stall) toilet as an example, its conventional dimensions are approximately 2.5m × 1.5m × 2.3m (length × width × height) (double stalls + shared sink). This design takes into account the needs of multiple people using the toilet simultaneously and also saves some space by sharing a sink.
Barrier-free mobile toilets are designed to be convenient for people with disabilities. Their space dimensions are significantly larger than those of standard single-unit toilets. In common specifications, the length and width are usually more than 1.8 meters, and the internal height is approximately 2.5 meters. There are also stricter requirements, stating that the dimensions of barrier-free public toilets should be at least 2.0m × 1.5m × 2.4m (length × width × height), and a wheelchair turning space of at least 1.5m × 1.5m should be reserved to ensure that wheelchairs can rotate freely inside the toilet, facilitating use by people with disabilities.
Trailer-mounted mobile toilets have dimensions similar to those of large single-unit or small row-type toilets. They combine the needs for mobility and usage space, allowing them to be conveniently moved to different locations by towing while also providing relatively spacious usage space.
