Bathroom signs typically include symbols and text to indicate the purpose of the facility. These can range from simple symbols like 'Men' and 'Women' to more detailed signs specifying accessible toilets, family restrooms, and baby changing stations. They often adhere to international standards for accessibility and safety. In the United States, for example, the Americans with Disabilities Act (ADA) governs the design and placement of these signs. Internationally, symbols are often standardized by organizations such as the World Health Organization (WHO) and the International Organization for Standardization (ISO).
