Dimensions of Portable Toilets at Construction Sites in Kunming

There is no unified standard for the dimensions of portable toilets at construction sites in Kunming; they are usually customized according to the usage scenario and requirements. The following are common standard dimensions and dimensions for special needs:

The dimension design of single-stall portable toilets needs to balance user comfort and space utilization. The regular single-person type generally has dimensions of 110 cm in length, 110 cm in width, and 230 cm in height. Such dimensions can meet basic toilet needs and are suitable for construction sites with a relatively small flow of people. If further space saving is required, the mini single-person type has dimensions of 100 cm in length, 100 cm in width, and 220 cm in height. However, it should be noted that such dimensions may limit the user's range of movement and are only recommended for temporary or short-term projects. In addition, the width of single-stall dimensions is usually 1.0 - 1.2 meters, the depth is 1.0 - 1.5 meters, and the height is 2.0 - 2.5 meters. These ranges can be flexibly adjusted according to the actual needs of the construction site, for example, by increasing the depth to accommodate additional facilities such as storage cabinets or sinks.

The dimensions of multi-stall combined portable toilets need to be expanded according to the number of squatting positions. The overall width of a double-squatting-position toilet is approximately 2.0 - 2.4 meters, with the same depth and height as a single stall. This design can accommodate 2 - 3 people using it simultaneously and is suitable for medium-sized construction sites or areas with a concentrated flow of people. The double-person type usually has dimensions of 180 cm in length, 110 cm in width, and 230 cm in height, achieving a double-squatting-position layout by extending the length. However, it is necessary to ensure that the width of the aisle is not less than 0.8 meters to avoid usage conflicts. For larger-scale construction sites, a modular design can be adopted, where multiple single-stall or double-stall units are spliced together to form a linear or circular layout, and the overall dimensions can be infinitely expanded according to project requirements.

Special-need scenarios need to follow barrier-free design specifications. The width of a barrier-free toilet should be ≥ 1.5 meters and the depth should be ≥ 1.8 meters. Such dimensions can accommodate the turning space of a wheelchair and auxiliary facilities (such as handrails and emergency call devices). The dimensions of a portable toilet suitable for barrier-free needs are generally 180 cm in length, 150 cm in width, and 240 cm in height. The increased height facilitates use by people with mobility impairments, and at the same time, it is necessary to ensure that the door width is not less than 0.9 meters to support wheelchair access. In addition, some construction sites may need to be equipped with nursing rooms or management rooms. The dimensions of such functional portable toilets need to be further customized according to specific equipment (such as baby changing tables and office desks).
