Specifications and Models of Public Mobile Toilets

Public mobile toilets come in a variety of specifications and models, primarily categorized into single-stall, double-stall, multi-functional, and special-specification types. Specific designs should be tailored to the usage scenario, ergonomics, and industry standards.

I. Common Specifications and Models

1. Single-Stall Mobile Toilet

   • Dimensions: Length 1.2-1.5 meters (commonly 1.2 meters in Xinyang municipal projects), width 1.0-1.2 meters (commonly 1.0 meters in Xinyang municipal projects), height 2.2-2.5 meters (commonly 2.0 meters in Xinyang municipal projects).
   • Suitable Scenarios: Construction sites, small events (e.g., community renovations, small exhibitions).

2. Double-Stall Mobile Toilet

   • Dimensions: Length 2.4-3.0 meters (approximately 1.5 meters for double-stall units in Xinyang municipal projects), width 1.2-1.5 meters (commonly 1.2 meters in Xinyang municipal projects), height 2.2-2.5 meters (commonly 2.2 meters in Xinyang municipal projects).
   • Suitable Scenarios: Large events, tourist attractions (e.g., music festivals, sports events).

3. Multi-Functional Mobile Toilet

   • Dimensions: Length 3.0-4.5 meters, width 2.0-2.5 meters, height 2.5-3.0 meters.
   • Suitable Scenarios: High-end events, long-term fixed locations (e.g., commercial launches, weddings).

4. Special Specifications

   • With Accessibility Features: Dimensions approximately 1.8 meters × 1.5 meters × 2.3 meters, equipped with handrails and a toilet seat, suitable for government projects and large public venues.
   • Eco-Friendly Type: Spacious interior with a sink and hooks, designed for scenic spots and parks with high environmental requirements.
   • Luxury Type: Dimensions approximately 2.0 meters × 1.8 meters × 2.5 meters, featuring an aroma system and independent lighting, suitable for high-end occasions.
   • Multi-Stall Combination: Length exceeding 6 meters, width exceeding 2.5 meters, containing multiple toilet stalls and a management room, requiring factory prefabrication and overall transportation.

II. Design Considerations

• Ergonomics: The net width of the toilet stall should be ≥0.85 meters (ideally 0.9-1.0 meters), with a net depth of 1.2-1.5 meters and a door width of ≥0.6 meters; for accessible stalls, the net width should be ≥1.5 meters and the net depth ≥1.8 meters. The recommended height for the sink is 0.8-0.9 meters.
• Material Selection: Prioritize lightweight, high-strength composite materials (e.g., fiberglass) to reduce weight and facilitate transportation.
• Waterproofing and Moisture Resistance: Design a drainage system at the bottom and use waterproof materials for the walls to ensure long-term use without leakage.

III. Industry Standards and Precautions

• Standard Requirements: Must comply with the 'Urban Public Toilet Design Standard' (CJJ 14-2016), with some regions imposing additional regulations on dimensions and environmental performance.
• Transportation and Installation: Consider road height and width restrictions during transportation; ensure the ground is level during installation to prevent tilting.
• Maintenance and Management: Regularly inspect the drainage system and ventilation equipment to prevent blockages and odor buildup.
