Why Mobile Toilets Don't Use Toilets

Mobile toilets do not use toilets primarily due to considerations of hygiene, maintenance, durability, space utilization, and flushing requirements.

1. Hygiene Issues
The hygiene of public toilets is one of the most important factors for users. When using a toilet seat, the buttocks come into direct contact with the surface of the toilet, which can easily leave behind bodily fluids, bacteria, or viruses. Especially in scenarios lacking timely cleaning, the risk of cross-infection significantly increases. In contrast, squat toilets reduce skin contact through physical isolation, which better aligns with the public's psychological expectations for public hygiene. Even if mobile toilets are equipped with disposable seat covers or disinfection equipment, users may still choose to avoid using them due to psychological barriers, resulting in a lower actual usage rate of toilets.

2. Inconvenient Maintenance
Toilets have a complex structure, including components such as water tanks, flush valves, and seals, which require regular maintenance to ensure normal flushing, leak prevention, and odor control. If maintenance is not timely, issues such as weak flushing, pipe blockages, or odor diffusion may arise, affecting the user experience. In contrast, squat toilets have a simple structure and only require regular cleaning of the toilet bowl and drainage pipes, resulting in lower maintenance costs. They are more suitable for scenarios where mobile toilets need to be frequently moved or temporarily deployed.

3. Prone to Damage
Toilets in public toilets are often damaged due to human actions (such as kicking or hitting with heavy objects) or improper use (such as standing on them), requiring the replacement of the entire toilet or core components, which is costly. Squat toilets, made of ceramic or stainless steel, are more resistant to impact and have no vulnerable components such as water tanks. Even if they are partially damaged, they are easier to repair, reducing the maintenance pressure during long-term operation.

4. Space Occupation
The design of mobile toilets needs to balance functionality and portability, and the internal space is usually relatively compact. Toilets require a water tank and a seat, occupying 20%-30% more space than squat toilets, which may limit the user's activity space or reduce the number of facilities that can be accommodated in the toilet (such as handrails and storage shelves). Squat toilets can be installed compactly, providing more flexibility for small-space design.

5. Flushing Issues
Some mobile toilets use packaging or waterless flushing technologies, treating excreta through biodegradation, vacuum suction, or chemical agents, eliminating the need for traditional flushing systems. Toilets have a large flushing volume (usually 6-9 liters per flush), which conflicts with water-saving or waterless designs. In contrast, squat toilets can reduce residue by optimizing the drainage slope, making them more suitable for such environmentally friendly technologies. Even if equipped with a water tank, the flushing noise and splashing issues of toilets may affect the user experience, especially at night or in quiet environments.
