Internal Specifications of Mobile Toilets

The internal specifications of mobile toilets are designed around the needs of hygiene, convenience, and durability, covering modules such as sanitary ware, environmental control, water supply and drainage, and power systems, as well as structural components. Details are as follows:

1. Core Sanitary Ware

• Toilets: Primarily ceramic squat toilets or sit-down toilets, with high-end products using stainless steel. The water tank capacity ranges from 5 to 10 liters, equipped with foot-operated or sensor-operated flush valves for water conservation and hygiene.
• Handwashing Systems: Hand basins are 30-40 centimeters wide, mostly made of ceramic or stainless steel. Faucets are either push-type or sensor-operated, with storage tank capacities varying by model. Some products are equipped with warm water supply functions.
• Other Accessories: Standard features include mirrors, coat hooks, storage shelves (or plates), toilet paper holders, and trash bins. High-specification products add child safety seats, toilet seat covers, or hand dryers to enhance convenience.

2. Environmental Control Systems

• Ventilation Systems: Exhaust fans have a power range of 20-50 watts, with an air exchange rate of 10-15 times per hour. Dual exhaust designs can quickly eliminate odors; some products are equipped with activated carbon filtration units for further air purification.
• Lighting Systems: LED energy-saving lights have a power range of 5-15 watts, with adjustable brightness. Emergency lights automatically activate during power outages to ensure safety.
• Temperature Control Systems: In cold regions, insulation materials, electric heaters, or warm air blowers are installed to maintain internal temperatures above 5°C. In hot regions, ventilation skylights or small air conditioners are added to control temperatures below 30°C.

3. Water Supply and Drainage, and Power Systems

• Water Supply Systems: Freshwater tanks have a capacity of 100-300 liters (for self-contained tank models) or can be directly connected to municipal water pipes (for external water source models). Some products are equipped with water circulation systems for water-saving operation.
• Sewage Systems: Traditional products have sewage tanks with a capacity of 200-500 liters, requiring regular cleaning. Environmentally friendly models use foam sealing (to reduce odors) or microbial degradation technology (for no sewage discharge), reducing maintenance costs.
• Power Systems: Support for 220V mains power connection, or power supply through built-in batteries (such as 12V/100Ah) and solar panels to meet basic needs like lighting and ventilation. High-end products are equipped with inverters to support high-power equipment like air conditioners.

4. Structural Components and Accessories

• Door Locks and Indicators: Internal safety door locks are installed, with external "Occupied/Unoccupied" indicator locks or LED displays to prevent accidental pushing; some products are equipped with voice prompt functions.
• Materials and Flooring: Wall panels are made of high-density polyethylene (HDPE), fiberglass, or color-coated steel plates, providing moisture and corrosion resistance. The floor is laid with anti-slip flooring or fiberglass grating to prevent water accumulation.
• Barrier-Free Facilities: Toilets for special populations have larger internal spaces (width ≥ 1.5 meters), equipped with handrails, wheelchair turning spaces (diameter ≥ 1.5 meters), and low-height hand basins (height ≤ 80 centimeters), complying with barrier-free design standards.

5. Overall Size Examples
A common specification for a mobile toilet with four squat positions and a handwashing area is 6 meters in length. Assembled mobile restrooms may have dimensions of 2.5 meters × 6.5 meters (divided into three separate areas). Specific dimensions should refer to national standards such as GB/T 26963-2011 Mobile Toilets. The richer the configuration (such as air conditioners, water heaters, etc.), the higher the price and maintenance costs.
