Mobile Toilet

A mobile toilet is a facility that can be moved as a whole and provides public toilet services. It is suitable for various places and has multiple types and features.

Applicable Places

Mobile toilets are suitable for stations, docks, tourist attractions, villa areas, newly built residential communities, large construction sites, squares, densely populated public places, and bustling commercial streets. These places often have temporary or periodic demands for toilets, or it is relatively difficult to build fixed public toilets. Mobile toilets can effectively make up for the shortcomings of insufficient public toilet supply and unreasonable layout. For example, in 2023, mobile toilets in the Lanzhou Yellow River Scenic Area were gradually installed and put into use, meeting the toilet needs of tourists.

Composition Structure

Generally, it consists of a fecal sewage storage tank (or fecal sewage treatment device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobile device. The specific composition may vary for different types and designs of mobile toilets.

Development History and Types

Initially, mobile toilets were made of materials such as wood, with simple structures and functions, and were prone to absorbing odors. Later, they gradually developed to use materials such as fiberglass and polyethylene. According to the structural form, they can be divided into single-structure mobile toilets and composite-structure mobile toilets; according to the moving method, they can be divided into hoisting and handling mobile toilets, powered and towed mobile toilets; according to the sewage treatment method, they can be divided into water-flushing and non-water-flushing suction-type mobile toilets, circulating water-flushing mobile toilets, and dry-packing mobile toilets.

Features and Advantages

It can be conveniently transported to any place where a toilet needs to be set up and can be used repeatedly. It has the advantages of mobility, combinability, and convenient transportation.

Design Principles and Examples

The design should follow the principles of mobility and convenience, economic durability, environmental protection and ecology, and improving efficiency and promoting humanity. The overall structure should be considered to be lightweight, and lightweight and durable materials should be used as much as possible; the structure should be sturdy; the height and width of the toilet should also be considered during design; the mobile device should be fully considered for completeness and rationality. For example, a new Chinese-style mobile public toilet is designed with a total of 6 squatting positions, 3 for men, and a common washing area in the middle. The exterior material is metal carved panels, and the steel structure frame is welded. It can be used outdoors for more than 15 years without any problems, with complete water and electricity supplies; a one-piece mobile public toilet has a one-piece outer shell + reinforced chassis, an internal vacuum squatting pan, and pneumatic flushing. A single flush requires only 1 liter of water, saving 80% compared to ordinary toilets.
