Toilet signs are used to indicate the location of a restroom in public areas. They often feature symbols such as a human figure with a urine stream or a human figure with a skirt, along with the word 'Toilet' or 'Restroom'. These signs are designed to be universally recognizable and are usually placed at the entrance of restrooms. In some cases, additional signs may be used to indicate gender-specific restrooms, such as 'Men's' or 'Women's'.
