Detailed Parameters of Mobile Toilet Sizes
The detailed parameters of mobile toilet sizes vary depending on the type and usage scenario, as follows:
Single-compartment Mobile Toilet The length typically ranges from 1.1 to 1.5 meters (with some standards specifying 1.2 to 1.5 meters), the width from 1.0 to 1.2 meters, and the height is based on 2.2 meters (with some standards specifying 2.2 to 2.5 meters). The internal space design must meet ergonomic requirements: the net width of the toilet compartment is recommended to be no less than 0.9 meters, the depth from 1.2 to 1.5 meters, and the door width must be at least 0.6 meters to facilitate easy access for people. This type of toilet is suitable for construction sites, small events, etc., and care should be taken to avoid difficulties in turnover during peak usage periods due to overly small sizes.
Double-compartment Mobile Toilet The length ranges from 2.4 to 3.0 meters, the width from 1.2 to 1.5 meters (with some standards specifying 1.0 to 1.2 meters), and the height from 2.2 to 2.5 meters. Its design must accommodate the needs of multiple people using it simultaneously and is suitable for large events, tourist attractions, etc. The differences in width in some standards may be related to structural optimization or transportation limitations, and selection should be based on actual needs.
Multi-functional/Large Mobile Toilet The length can reach 3.0 to 6.8 meters (e.g., 6.8 meters long for a double-occupancy unit, with container-type units exceeding 6 meters), the width from 2.0 to 2.5 meters (with container-type units exceeding 2.5 meters), and the height from 2.5 to 3.0 meters. This type of toilet is often used for high-end events or long-term fixed locations and may include multiple toilet compartments, barrier-free facilities, and a management room. Its size must meet the requirements for complex functional layouts, such as barrier-free access and equipment storage space.
Barrier-free Toilet Compartment The internal net width must be ≥1.5 meters, the net depth ≥1.8 meters, and the door width must allow wheelchair access. The design must accommodate wheelchair turning space and comply with the specifications for barrier-free facilities in the Design Standard for Urban Public Toilets (CJJ 14-2016).
Design Considerations and Industry Standards All types must comply with national standards, and some regions may have additional requirements. During transportation, road height and width restrictions (e.g., height not exceeding 4.5 meters) must be considered, and during installation, the ground must be level to avoid structural deformation. The internal layout must balance ergonomics (e.g., sink height of 0.8 to 0.9 meters) and waterproof and moisture-proof design. Due to technical characteristics, foam-type public toilets may have an internal space that is 10 centimeters wider than their appearance.
