Mobile Toilet Water Tank Size

Admin September 22, 2026

There is no direct unified standard for the size of mobile toilet water tanks, and the sizes of different types of water tanks vary. Here is a detailed analysis:

Basic dimensions of low water tanks in automatic flushing tanks for public toilets: The low water tanks in automatic flushing tanks for public toilets have a certain range of basic dimensions. The height is usually between 70 and 80 centimeters, and the width is between 30 and 40 centimeters. This size of water tank is suitable for some fixed public toilet facilities. Although mobile toilets and fixed public toilets have certain differences in structure and usage scenarios, such size data can serve as a reference for the design of mobile toilet water tank sizes, as they both have the function of storing and supplying water for toilet flushing.

Relationship between the overall dimensions of mobile public toilets and water tank sizes: For mobile public toilets, the external dimensions of a common single-pit unit are generally between 1.2 and 1.5 meters in length and between 1.0 and 1.2 meters in width. In multi-pit combined units, the length of a two-pit unit may reach between 2.4 and 3.0 meters, while the width remains between 1.0 and 1.2 meters. However, these overall dimensions do not explicitly mention the specific sizes of the water tanks. Nevertheless, from the perspective of overall spatial layout, the size of the water tank needs to match the overall structure of the toilet. It should ensure sufficient water storage capacity while not taking up too much space and affecting the use and passage inside the toilet.

Doubts about the size and applicability of wall-mounted water tanks: The thickness of wall-mounted water tanks is generally between 12 and 20 centimeters, with a width of 55 centimeters and a depth of 2 centimeters. However, it is currently uncertain whether such wall-mounted water tanks are suitable for mobile toilets. Due to the mobility of mobile toilets, more factors need to be considered when designing and installing water tanks, such as the fixing method of the water tank and its stability during movement. If a wall-mounted water tank is installed on a mobile toilet, special fixing devices and structural designs may be required to ensure that it does not loosen or get damaged during movement.
