Double-Toilet Mobile Restroom Configuration

The configuration of double-toilet mobile restrooms typically covers six core modules: size and structure, sanitary fixtures, environmental control, water supply and drainage and power systems, structural accessories, and industry adaptability, as detailed below:

1. Size and Structure
The basic dimensions of double-toilet mobile restrooms vary by model, with common specifications being 2.5-3 meters in length, 2.6 meters in width, and 3 meters in height, accommodating two independent toilet compartments. The exterior walls are often made of metal carved panels, high-density polyethylene (HDPE), or fiberglass-reinforced plastic, offering both corrosion resistance and aesthetic appeal, with neutral colors such as brick red and gray being predominant. The step height is typically 500 millimeters, equipped with dedicated restroom doors and 'Occupied/Vacant' signs, with some high-end models featuring LED displays to indicate usage status in real time.

2. Core Sanitary Fixtures

• Toilets: Ceramic squat toilets are the mainstay, with some high-end products opting for stainless steel, paired with foot-operated or sensor-activated flush valves to minimize contact contamination.
• Handwashing Systems: Standard configurations include ceramic or stainless steel handwashing basins, equipped with push-type or sensor-activated faucets, and a water storage tank (capacity 100-300 liters) to ensure water supply.
• Accessories: These include mirrors, coat hooks, shelves, toilet paper holders, and trash bins, with some models adding child safety seats or toilet seat covers to enhance convenience.

3. Environmental Control Systems

• Ventilation: Standard configurations include 20-50 watt high-power exhaust fans, with some models adopting dual exhaust designs on the top and side walls to accelerate odor removal.
• Lighting: 5-15 watt LED energy-saving lights are used, with some models equipped with emergency lights to ensure illumination during power outages.
• Temperature Control: In cold regions, insulation materials, electric heaters, or warm air blowers are installed; in hot regions, ventilation skylights or small air conditioners are added to maintain a comfortable internal temperature.

4. Water Supply and Drainage and Power Systems

• Water Supply: Models with built-in water tanks feature a clean water tank (100-300 liters) on top, or can be connected to municipal water pipes; the sewage system uses a sewage tank (200-500 liters), foam sealing, or microbial degradation technology to reduce odors and cleaning frequency.
• Power: Supports 220V mains power connection, or can be powered by built-in batteries and solar panels, adapting to scenarios without external power sources.

5. Structural Accessories

• Safety Design: Internal safety door locks are installed, with external 'Occupied/Vacant' indicator locks or LED displays.
• Materials and Flooring: Wall panels are made of HDPE, fiberglass-reinforced plastic, or color-coated steel plates, with non-slip flooring or fiberglass floor grilles to prevent slipping.
• Accessibility Features: Some models include handrails, wheelchair turning spaces, and low-level handwashing basins to meet the needs of special populations.

6. Industry Configuration References

• Large Events: One standard restroom is configured for every 200-300 people, with a male-to-female ratio of 1:1.5, and additional accessible restrooms and母婴室 (nursing rooms) are provided.
• Municipal Projects: Flexible configuration based on project duration and construction workforce size, with priority given to waterproof and corrosion-resistant materials to adapt to harsh outdoor environments.
