Dimensions of Portable Toilets at Construction Sites in Lijiang

The dimensions of portable toilets at construction sites in Lijiang vary depending on the type and usage requirements, with common specifications as follows:

I. Single-Compartment Portable Toilets
The dimensions of single-compartment portable toilets are designed to meet basic usage needs while optimizing space utilization. Their width typically ranges from 1.0 to 1.2 meters, depth from 1.0 to 1.5 meters, and height from 2.0 to 2.5 meters. These dimensions are suitable for single-person independent use, accommodating basic facilities such as a toilet or squat pan and a sink inside. They are ideal for construction sites with high personnel turnover. Some ready-made single-person portable toilets have more standardized dimensions, such as approximately 1.1m × 1.1m × 2.3m in length, width, and height, facilitating mass production and transportation.

II. Multi-Compartment Combined Portable Toilets
The dimensions of multi-compartment combined portable toilets need to be adjusted according to the number of squat positions. For example, a double-squat-position portable toilet typically has an overall width of about 2.0 to 2.4 meters, with the length determined by actual needs. Usually, the combined length of two toilet compartments needs to reach 6 to 8 meters to meet the demand for simultaneous use by multiple people. Additionally, some construction sites may adopt wider specifications, such as a width set between 3 to 4 meters, with the length extended flexibly according to the number of users. This design is suitable for densely populated construction areas. The dimensions of ready-made double-occupancy portable toilets are usually 2.5 meters in length, 1.1 meters in width, and 2.3 meters in height, achieving space sharing by extending the length.

III. Portable Toilets for Special Needs
For special populations or functional requirements, the dimensions of portable toilets need further optimization. For example, barrier-free toilets require a width of ≥1.5 meters, a depth of ≥1.8 meters, and a height of about 2.4 meters to ensure sufficient space for wheelchair access and turning. Such designs need to comply with barrier-free facility specifications and are usually equipped with auxiliary facilities such as handrails and low-position sinks inside. In addition, the dimensions of small portable folding toilets can be reduced to 1m × 1m × 2m, suitable for temporary or space-constrained construction site scenarios, with their lightweight design facilitating rapid deployment and mobility.

IV. Standardized Specifications of Ready-Made Portable Toilets
The dimensions of ready-made portable toilets on the market tend to be standardized. For example, the dimensions of single-person, double-person, and barrier-free models are 1.1m × 1.1m × 2.3m, 2.5m × 1.1m × 2.3m, and 1.5m × 1.8m × 2.4m, respectively. These specifications have been optimized to balance functionality and cost-effectiveness and may be directly adopted by construction sites in Lijiang or slightly adjusted according to actual needs.
