Ask what kids like about each design, what they dislike. Check videos of kids using potties. Potty training educational videos...

You need to prototype the experience. That's key.

Islam symbols - Colour

These four Pan-Arab colours, white, black, green and red, dominate the flags of Arab states. The colour brown is often believed to symbolize purity and peace. Many Muslims wear the colour white when they attend Friday prayers.

Assignment for Oct 9

Comments from guests and peers

They do not have specific toilets allocated to each family/ age-group. There is a separation between the male and female toilet, but males in the Rohingya camp doesn't really follow the rules and will use the female toilets. (provided by WASH)
There is shortage in toilets for both male and female.
The toilets in Rohingya camps are squat toilets.
Consider the protection for users using the latrines, including lighting, locks for privacy and location of latrines.
For the idea of kids portable, considering the colour and design.

Further research

People in Bangladesh and in Rohingya camp does not use toilet paper, they will use their hands and wash with water.
In respect to the culture of the camp, it is to be considered whether the design will respond with the normal practice/routine of the people. ie. People are used to use squat toilets in the camp, they might not be comfortable using sitting toilets

To consider how to dispose faeces and urine. Plastic bags are not to promoted, and normally faeces are to be disposed to the latrines.

I would suggest you make a comprehensive survey of kids toilets out there and understand

  • the value proposition for each of these toilets

  • think of adapting it to this culture, climate, materials, budget...


-will there be dried leaves or cover material available and collected which is ready for use

-for pee potty, the position of the opening will cause difficulties to pour the urine completely out
