Creative designs for men's and women's toilet signs often include distinctive symbols or icons that are easily recognizable. These designs may incorporate elements such as the silhouette of a person using the toilet, a urinal for men, and a cubicle or stall for women. Additionally, color coding is a common practice where blue is often used for male toilets and pink or purple for female toilets. The goal is to ensure clarity and accessibility for users of all ages and backgrounds.
