I've never heard of Unisex before. Let me do some research.

Uni = of one. examples: Unicorn, Unibrow, Unicycle.
Sex = sexually motivated phenomena or behavior.

Hmmm... interesting...

Bathroom = A room equipped with facilities for taking a bath or shower and usually also containing a sink and toilet.


My definition of a Unisex Bathroom = A Room equipped with facilities for having sex alone.

They have rooms like that?
