Toilet promoters believe the female urinal could halve queues at women's toilets in the city.
The device will feature in an exhibition of more than 30 toilets through the ages, which opens tomorrow at the Convention and Exhibition Centre.
The Hong Kong Toilet Association wants women visiting the exhibition to try out the urinal and tell members what they think of it.
'Female urinals are widely used in public toilets in Amsterdam,' said the association's secretary, Henry Hung Chi-kuen. He said portable versions, made of paper or plastic, were also available.
Vice-president Lo Wing-lok said the association would evaluate the feedback from women who used the urinal at the three-day show.
'Shopping centres interested in providing this facility can contact the association and we can help to launch a pilot scheme,' Dr Lo said.
The association said the ratio of men's public toilets to women's was one to one in Hong Kong. This was unfair and out of date.
'The proportion should be changed to 1 to 1.7, since nowadays more women go out for work, shopping and entertainment,' Dr Lo said.
He said the ratio had not changed since the late 1950s.
The Toilet Forest Exhibition runs until Sunday and will show the toilet's past, present and future.
Among the exhibits is a wooden toilet in the shape of a chair, with a removable bucket, which was widely used by the Russian nobility in the 19th century.
A fully automated Japanese toilet will also be on display.
