If no proper washrooms are available, simple shower constructions can be designed so women and girls, older persons and persons with disabilities can manage their personal hygiene independently, safely and with dignity.
An example:
Hang a four-litre jerry can with 10 holes near the top and a rope to pull for the water to pour out. Recycled and cleaned tyres allow persons having difficulty to balance or stand, to sit while having shower.
Holes for light and ventilation are placed high enough on the walls to avoid view from the outside.
A pulling-rope system is made, with a rope attached to the door and treading through a hook. The person pulls the string to close the door and ties the end to a handrail.
There are separate showers for men and boy, and for women and girls.
