Recommended Design Sizes for Mobile Toilets

The design sizes of mobile toilets need to be determined according to their types and usage scenarios. The following are common recommended sizes:

I. Classification by Toilet Type

1. Single-unit Mobile Toilet

   • Length: 1.2 - 1.5 meters, suitable for scenarios with limited space and relatively low demand.
   • Width: 1.0 - 1.2 meters, ensuring enough space for turning around and installing equipment inside.
   • Height: 2.2 - 2.5 meters, meeting the requirements for ventilation and equipment installation while avoiding a sense of oppression.
   • Applicable Scenarios: Construction sites, small-scale events, temporary exhibitions, etc., mainly for short-term and high-frequency use.

2. Double-unit Mobile Toilet

   • Length: 2.4 - 3.0 meters, accommodating two independent toilet compartments and aisles.
   • Width: 1.2 - 1.5 meters (some designs still use 1.0 - 1.2 meters), adjusted according to the layout of the toilet compartments.
   • Height: 2.2 - 2.5 meters, the same as that of single-unit toilets, ensuring good internal air circulation.
   • Applicable Scenarios: Large-scale events, tourist attractions, etc., meeting the needs of multiple people using them simultaneously.

3. Multi-functional Mobile Toilet

   • Length: 3.0 - 4.5 meters, integrating functional areas such as toileting, hand-washing, and management.
   • Width: 2.0 - 2.5 meters, reserving space for equipment maintenance and personnel passage.
   • Height: 2.5 - 3.0 meters, adapting to the installation of ventilation systems and lighting equipment.
   • Applicable Scenarios: High-end events, long-term fixed locations (such as parks and service areas), emphasizing comfort and functionality.

II. Size Specifications for Internal Functional Areas

1. Toileting Area

   • Net Width: Should not be less than 0.85 meters, with an ideal range of 0.9 - 1.0 meters, ensuring normal activities for users.
   • Net Depth: 1.2 - 1.5 meters, accommodating a toilet, a trash can, and legroom.
   • Door Width: Not less than 0.6 meters, meeting the requirements for wheelchairs or equipment to enter and exit.

2. Barrier-free Toilet Compartment

   • Internal Net Width: Should reach more than 1.5 meters, reserving space for wheelchair turning and the operation of assistive personnel.
   • Net Depth: Should reach more than 1.8 meters, adapting to the installation of barrier-free toilets and handrails.
   • Design Points: It should adopt a swing door or an outward-opening design to avoid occupying internal space.

III. Design Considerations

1. Space Utilization: Adjust the number of toilet compartments according to the frequency of use to avoid overcrowding or waste of resources.
2. Ventilation and Lighting: The height should be adapted to the ventilation system, and the width should ensure coverage by natural or artificial light.
3. Barrier-free Design: Public places should set up barrier-free toilet compartments in accordance with regulations to ensure convenience for special groups.
4. Material Selection: Waterproof, anti-slip, and easy-to-clean materials should be selected to extend the service life and reduce maintenance costs.
