What is the Suitable Width of a Mobile Toilet for Children?
If a mobile toilet is primarily designed for children, the recommended width for a squat toilet is 220mm, and for a sitting toilet, it is recommended to be between 36cm and 40cm. If it is necessary to accommodate children's activity space, the interior width can be appropriately adjusted to between 1.2 meters and 1.5 meters, but the core focus remains on fitting children's body sizes.

Squat Toilet Width: 220mm as the Key Dimension for Fitting Children's Body Sizes
The width of squat toilets designed for young children is typically reduced to 220mm. This dimension is determined based on the average hip width and leg movement range of children, ensuring that it meets children's natural squatting posture during toilet use while avoiding the risk of instability or stepping off due to excessive size. If the mobile toilet is equipped only with a squat toilet and primarily serves preschool children, a width of 220mm is the core design parameter.
Sitting Toilet Width: 36cm-40cm Balancing Comfort and Space Efficiency
If the mobile toilet is equipped with a children's sitting toilet, its width needs to cover the space for children's buttocks and leg movements. According to children's ergonomics data, a width of 36cm-40cm can accommodate the body sizes of children aged 3-12, avoiding discomfort during toilet use due to excessive narrowness and preventing excessive occupation of interior space due to excessive width. For example, a width of 36cm is suitable for young children, while a width of 40cm can meet the activity needs of slightly older children.
Interior Space: 1.2 Meters-1.5 Meters Accommodating Activity and Assistance Needs
If the mobile toilet needs to meet the scenarios of children using it independently or with parental assistance, the interior width needs to be appropriately expanded. Referring to the wheelchair turning space in barrier-free facilities (1.5 meters), the interior width of children's mobile toilets can be adjusted to between 1.2 meters and 1.5 meters:
- 1.2-meter width: Suitable for a single child, allowing the child to stand, turn around, and receive brief parental assistance (such as tidying up clothes);
- 1.5-meter width: Suitable for young children and parents using it simultaneously, or for setting up facilities such as children's sitting toilets and auxiliary handrails to enhance safety and convenience.
It should be noted that the core design logic of children's mobile toilets is to 'fit body sizes' rather than 'completely follow adult standards'. If space is limited, priority can be given to ensuring that the width of the toilet fits children's body sizes, and then space utilization can be improved by optimizing the interior layout (such as using folding doors and reducing unnecessary decorations).
