Non-movable Public Toilet

Non-movable public toilets generally refer to fixed public toilets, which are types of public toilets that cannot be moved as a whole. Their core characteristic is that they are fixed in position and permanently connected to the building structure.

Basic Definition of Fixed Public Toilets

Fixed public toilets are an important part of urban infrastructure, and their 'non-movability' is reflected in the fixed connection between the building structure and the foundation. These toilets are usually constructed through methods such as concrete pouring and brick walls, forming a stable connection with the ground and cannot be relocated as a whole by mechanical means. Their original design intention is to meet the long-term and stable toilet needs of specific areas, such as commercial streets, parks, transportation hubs, and other densely populated places.

Classification and Characteristics of Independent Public Toilets

Independent public toilets are one of the main types of fixed public toilets, and their notable feature is that they do not depend on other buildings but exist as independent structures. According to the 'Urban Public Toilet Design Standard' (CJJ 14-2016), independent public toilets are classified into three categories based on the surrounding environment and architectural design requirements:

• Class I Public Toilets: These are mostly located in urban core areas, commercial centers, or tourist attractions. Their architectural style is in harmony with the surrounding environment, and they are equipped with complete internal facilities, usually including barrier-free access, third toilets, baby care rooms, etc., and adopt intelligent equipment such as automatic induction flushing and ventilation and deodorization systems.
• Class II Public Toilets: These are commonly found in general commercial areas, residential areas, or main traffic roads. The facility standards are slightly lower than those of Class I, but they still need to meet basic sanitation needs, such as independent squatting stalls, hand-washing basins, lighting, and ventilation.
• Class III Public Toilets: These mainly serve remote areas or temporary venues. The facilities are relatively simple and may use trough-type toilets, but it is necessary to ensure smooth drainage and regular cleaning.

Design Considerations for Non-movability

The non-movability of fixed public toilets stems from multiple design considerations:

1. Structural Stability: Independent buildings need to bear their own weight and external loads (such as wind and earthquakes). Fixed structures can ensure long-term safe use.
2. Service Continuity: A fixed location makes it easier for citizens to form usage habits and avoids service interruptions caused by relocation.
3. Environmental Harmony: The exterior design of independent toilets needs to blend with the surrounding landscape, and fixed structures are more conducive to long-term maintenance and renovation and upgrading.

Comparison with Mobile Toilets

In contrast to fixed public toilets are mobile toilets (such as container toilets and trailer toilets), which are characterized by rapid deployment and relocation through modular design and are suitable for temporary events, disaster relief, and other scenarios. However, the capacity, facility standards, and service life of mobile toilets are usually lower than those of fixed ones, and regular maintenance is required to avoid structural aging.
