Usage Standards for Mobile Toilets in Guilin

The usage standards for mobile toilets in Guilin primarily cover capacity, dimensions, barrier-free design, and other service requirements, as detailed below:

I. Capacity Standards

Mobile toilets are categorized based on the number of toilet stalls and turnover rates:

1. Small Mobile Toilets: Contain 3-5 toilet stalls, suitable for small events or temporary settings, with a theoretical maximum simultaneous service capacity of 3-5 people.
2. Medium Mobile Toilets: Have 6-10 toilet stalls, suitable for medium-sized parks, scenic spots, or events with a larger number of attendees, with a simultaneous service capacity of 6-10 people.
3. Large Mobile Toilets: Feature more than 10 toilet stalls, possibly including barrier-free restrooms and baby care rooms, suitable for large-scale sports events, music festivals, or transportation hubs with heavy foot traffic, with a simultaneous service capacity exceeding 10 people.
4. Daily Usage Capacity: During peak hours (e.g., after an event ends), each toilet stall can serve an average of 8-12 people per hour, meaning a mobile toilet with 10 stalls can serve 80-120 people per hour.

II. Dimension Standards

The dimensions of mobile toilets vary depending on their type and function:

1. Single-Stall Mobile Toilets: Occupy an area of approximately 1.2㎡ to 1.8㎡, with internal clear dimensions typically measuring 1.2m to 1.5m in length × 1.0m to 1.2m in width, and a height of 2.2m to 2.5m.
2. Multi-Stall Mobile Toilets: Taking a double-stall toilet as an example, it occupies an area of about 3㎡ to 4㎡; for toilets with three or more stalls, each additional stall increases the usable area by approximately 1.5㎡ to 2㎡, with the overall length typically ranging from 3m to 6m and the width usually from 1.5m to 2.5m.
3. Barrier-Free Stalls: The internal clear dimensions must not be less than 1.8m × 1.4m, with a barrier-free ramp wider than 0.8m at the entrance and sufficient space reserved inside for wheelchair rotation.
4. Baby Care Rooms/Third Restrooms: These should generally have an area of not less than 4㎡, include facilities such as baby changing tables and child-sized toilets, and have a clear width of at least 1.5m to ensure operational space.

III. Barrier-Free Design Requirements

According to the General Code for Accessibility in Buildings and Municipal Engineering (GB 55019-2021), mobile toilets equipped with barrier-free facilities must comply with the following regulations:

1. They should be located near public restrooms, with an area of not less than 4.00 square meters, and include a wheelchair turning space with a diameter of not less than 1.5 meters inside.
2. They should be equipped with barrier-free toilets, barrier-free washbasins, multifunctional tables, low-positioned coat hooks, and emergency call devices.
3. They should have horizontally sliding doors or outward-opening hinged doors.

IV. Other Service Standards

1. Hygiene Standards: Equipped with flushing systems, non-slip floors, and ventilation devices, some include dedicated stalls for the disabled, with timely internal cleaning to prevent odor diffusion.
2. Environmental Requirements: Adopt water-saving flushing designs, with some products equipped with solar power systems to reduce energy consumption; they can be entirely recycled after use, minimizing environmental impact.
3. Service Coverage: Prioritize companies with service stations in Guilin for quick response to delivery and maintenance needs.
