The Porcelin Predicament

Greek woman and man statues

King Minos of Crete had the first flushing water closet in history and that was around 788 BC. 
I can easily imagine the joy it brought to his palace and to him personally, as he finally had a second throne. On his stone throne he could relax. He could read in peace. He could think, and so it was that the great ideas of mankind were born in that great country of Greece so long ago, in the bathroom.

Now women were not a big deal in Greece. Even though the Greek men dreamed up all kinds of goddesses, in the Greek household, women were small and submissive, while the male tall, strong and smart, spouted great ideas like,  "Woman! I have invented the toilet! It shall be the bane of mankind and the future of great nations. It shall be the throne of man and women shall clean it!"

Nothing, absolutely nothing, has been done in nearly 3000 years to change that. Toilet cleaning is assumed to be performed by a woman, and by law, no toilet design shall be allowed which makes the cleaning easier. Designers are encouraged to add nooks and crannies to make cleaning more difficult.
At the toilet factory: "Hey, John, how're are the new toilet plans coming along?"
"Great, Frank, This new one has more curves than a bowl of spaghetti! And I left in those little white cap things over the bolts, and it's still a pain to clean the seat part. But who cares? We don't have to clean those things! Bwa-ha-ha-ha!"

Men like their women and toilets curvey.

 Architects and plumbers, both suspiciously male people, are sworn to Article 6.3 of the Bathroom Code of Design wherein it states, "Every toilet installation shall be made as close to the wall as possible, and preferably only inches from the tub or shower. The plumbing and  lines to aforesaid toilet shall be twisty and shiny, allowing dust balls and other nasty afflictions to adhere to them easily. The line shall be braided to prevent sterilization."

Sign of intelligence on the planet

 Now for the good news. I think a female has sneaked into the toilet factory.  I saw a toilet seat in a public restroom, and it had a built-in handle protruding from the seat for easy and hopefully sanitary lifting. It's a small thing, but an opening, perhaps to a new age of restroom facilities. It means, ladies, that maybe someday we can visit a public restroom without bringing our own supply of rubber gloves and safety glasses. Perhaps we'll soon be able to leave the public restroom without first upholstering the door handle with a paper towel. Maybe there's a place somewhere in the universe, where women mess up the bathrooms and men clean them.
In your dreams.
