Mobile Toilet and Public Toilet Renovation: Squatting Positions

Adjustments to squatting positions in the renovation of mobile and public toilets should be selected based on specific scenarios and needs. Common adjustment methods include capacity expansion, layout optimization, and functional upgrades.

1. Adjustment of Squatting Position Quantity: Capacity Expansion and Layout Optimization
Some public toilet renovations achieve capacity expansion of squatting positions by optimizing internal space layouts. For example, a mobile public toilet in Huaiyin Park originally had 6 squatting positions. By adjusting the size of the stalls and the design of the aisles, the number of toilet positions was increased to 8, and a third restroom (including barrier-free facilities) was added. Such renovations need to focus on considerations such as the load-bearing capacity of the building structure, the matching of ventilation systems, and the rationality of user movement paths to avoid affecting the user experience due to space compression. After capacity expansion, the ventilation system should be upgraded simultaneously to ensure air circulation and prevent the accumulation of odors.

2. Material and Structural Upgrades: Adapting to Diverse Scenarios
The renovation of squatting positions should select materials and structures based on the usage scenarios. A five-squatting-position container toilet uses glass wool fireproof boards, which have fire-resistant, moisture-resistant, and corrosion-resistant properties, making them suitable for outdoor environments such as scenic spots and construction sites. The classic four-squatting-position mobile toilet, on the other hand, uses a steel frame structure paired with weather-resistant panels, balancing strength and durability, and is suitable for small to medium-sized venues. Material selection should take into account local climate conditions. For example, rust-resistant materials should be prioritized in humid areas, and enhanced insulation performance is required in cold regions.

3. Functional Adaptation: Meeting the Needs of Special Groups
Some renovation projects adjust the functions of squatting positions for specific groups. For example, in the age-friendly renovation in Pudong New Area, the general toilet stalls' squatting positions were changed to sit-down toilets, and the wall-mounted urinals were upgraded to floor-mounted ones to address the toilet needs of the elderly and children. Such renovations need to focus on detailed design, such as the height of the sit-down toilets, the installation position of handrails, and anti-slip treatment of the floor. At the same time, some squatting positions should be retained to meet the habits of different users. When adding barrier-free facilities, they should comply with the requirements of the "Barrier-Free Design Code," such as the toilet door width being no less than 0.9 meters and the internal space being no less than 1.8 meters × 1.4 meters.

4. Supporting System Upgrades: Enhancing the User Experience
Renovations of squatting positions are often accompanied by upgrades to supporting systems. The classic four-squatting-position toilet is equipped with ceramic squatting pans and a silent ventilation system, which can reduce noise and improve cleaning efficiency. Capacity expansion projects need to optimize the layout of water supply and drainage pipes simultaneously to avoid insufficient water pressure or poor drainage due to the increase in toilet positions. In addition, the introduction of intelligent monitoring systems (such as toilet occupancy indicator lights and pedestrian flow counting devices) can further improve management efficiency and alleviate queuing during peak hours.
