Female restrooms are toilet facilities designated for use solely by female persons, often with additional accommodation for washing, showering, changing clothes, or changing diapers.

This is only allowed as a main usage, and is applied only to buildings where some form of restrooms is a primary function.

Washing, changing, or similar facilities can accompany the toilets without changing the designated user group. The distinction concerns the facility's intended users, while its primary-function condition remains as stated above.
