Technical Specifications for Mobile Toilets

The technical specifications for mobile toilets cover aspects such as structure, dimensions, materials, functional configurations, design considerations, and industry standards, as detailed below:

I. Structural Forms

Mobile toilets are classified into monolithic structures and composite structures based on their construction. Monolithic structures are standalone units suitable for space-constrained scenarios; composite structures are composed of multiple units and can be expanded into multi-stall or multifunctional spaces. Based on mobility, they are categorized as hoisting/handling types (requiring lifting equipment) and powered/trailer types (equipped with their own power or towable), with the latter offering greater flexibility for temporary events or touring use.

II. Dimensional Specifications

• Single-stall mobile restrooms: Length 1.2-1.5 meters, width 1.0-1.2 meters, height 2.2-2.5 meters, suitable for construction sites and small events.
• Double-stall mobile restrooms: Length 2.4-3.0 meters, width 1.2-1.5 meters, height 2.2-2.5 meters, meeting the needs of large events or tourist attractions with high foot traffic.
• Multifunctional mobile restrooms: Length 3.0-4.5 meters, width 2.0-2.5 meters, height 2.5-3.0 meters, equipped with barrier-free facilities or management rooms, suitable for high-end venues.
• Kaifeng municipal standards: Common dimensions for single/double stalls are 1.2×2.5×2.3 meters, with custom models reaching over 3×4 meters, requiring space for equipment installation.

III. Materials and Load-Bearing Capacity

The main body is constructed from high-strength fiberglass or lightweight composite materials, with a compressive load-bearing capacity of ≥1500kg. The outer shell is waterproof and sun-resistant, with a service life of 8-10 years. Fiberglass is corrosion-resistant and easy to clean, while composite materials reduce weight for easier transportation. The bottom must incorporate a drainage system, and the walls should use waterproof materials to prevent leakage.

IV. Functional Configurations

• Basic configurations: Single stalls include a toilet, sink (some with sensor faucets), lighting, and ventilation systems; high-end models add air fresheners and emergency call devices.
• Water and electricity systems: Standard models come with built-in water tanks (approximately 200L capacity) and sewage tanks, with some requiring external municipal water and electricity connections; temporary models for construction sites often use solar power and rainwater harvesting systems for energy efficiency and environmental protection.
• Hygiene standards: The interior is lined with non-slip floor tiles and equipped with toilet paper holders and storage shelves; the exterior features signage and handrails, complying with the Urban Public Toilet Hygiene Standards (CJJ/T 14-2016).
• Special scenario adaptations: Models for tourist attractions emphasize aesthetic integration with the environment (e.g., wood-like or antique designs); those for construction sites focus on durability (e.g., mosquito screens and emergency lighting).

V. Design Considerations and Industry Standards

Stall widths should be ≥0.9 meters, and sink heights are recommended to be 0.8-0.9 meters to ensure user comfort. During transportation, road height and width restrictions must be considered, and installation requires a level ground to prevent tilting. Regular maintenance of drainage and ventilation systems is necessary to prevent blockages or odors. Rental services must provide product certification and hygiene inspection reports, prohibit the use of unqualified products, and comply with the relevant provisions of the Urban Public Toilet Design Standards (CJJ 14-2016).
