An Australian Dunny
A boy's urinal in a women's toilet, which is a good idea for mums not to have to worry about peadophiles lurking in the men's toilet.
In some countries they call the toilet John. I looked it up, and The term is thought to derive from Sir John Harrington. It is also sometimes called Jake.
Our grandparents on both sides didn't have Water closets, but dry toilets at the edge of the rubber garden. When we went to visit them for a weekend, Mother would hold on until she came home. We teased her that she grew up in that environment.
This is a Japanese toilet in Australia, Mum would have love using it.
