What is the Size of the Mobile Toilet Door?
There is no fixed standard for the size of mobile toilet doors, which need to be measured and determined according to the on-site structure. The common situations are as follows:

I. Thickness Specifications The thickness of mobile toilet doors directly affects their structural strength and applicable scenarios. Common thicknesses are divided into two categories:
- Small sliding doors: With thicknesses of 35mm, 40mm, and 50mm, they are suitable for scenarios with limited space or cost sensitivity. Among them, the 40mm thickness is widely adopted due to its high cost-effectiveness (balancing strength and cost).
- Large sliding doors: With thicknesses of 75mm and 100mm, they are suitable for scenarios with high stability requirements. The 100mm thickness is more favored due to its strong resistance to deformation and long service life.
II. Dimensions of Single-sided and Double-sided Sliding Doors The opening method of the door directly affects the reserved space dimensions:
- Single-sided sliding doors: A minimum clear width of 650mm needs to be reserved (i.e., the minimum distance between the door leaf and the wall or obstacle when the door is fully open). Architectural drawings usually indicate a door opening size of 700mm (including installation allowance). This size can accommodate smooth passage for a single person and is suitable for the internal layout of most mobile toilets.
- Double-sided sliding doors: A passage width of 650mm needs to be reserved (the minimum distance between the two door leaves when they are both open). The door width is generally 1300mm (a combination of two 650mm door leaves). If it is necessary to support the simultaneous passage of two streams of people (such as in barrier-free designs or peak usage scenarios), the door width needs to be expanded to 2200mm (a combination of two 1100mm door leaves).
III. Common Standard Sizes The mainstream door leaf sizes for mobile toilets on the market are as follows:
- Width: Commonly 80 centimeters (800mm) and 90 centimeters (900mm), which can meet the basic requirements of single-sided or double-sided sliding doors.
- Height: Usually between 1 meter and 2 meters (1000mm-2000mm). The specific height needs to be determined based on the internal clear height of the mobile toilet, ventilation requirements, and user habits. For example, barrier-free designs need to meet the passage height for wheelchairs (not less than 2100mm), but due to space limitations in mobile toilets, the height is mostly controlled within 2 meters to balance cost and practicality.
IV. Core Principles for Size Selection The size of mobile toilet doors needs to be determined by comprehensively considering the following factors:
- Usage scenario: Public places (such as scenic spots and construction sites) need to prioritize meeting peak pedestrian flow requirements, choosing double-sided sliding doors or expanding the door width; household or temporary usage scenarios can simplify the design.
- Space limitations: Adjust the door opening size according to the internal clear width, depth, and installation location (such as corners or independent spaces) of the mobile toilet to avoid structural conflicts due to excessive size.
- Cost and stability: Small sliding doors have low costs but relatively weak stability, while large sliding doors are the opposite. It is necessary to weigh and choose based on the budget and usage frequency.
