How far should light switch be from shower and bath?

Light switches should ideally be located at least 3 feet away from the edge of a shower or bathtub to ensure safety and minimize the risk of electric shock. In damp areas, such as bathrooms, it's also important to use switches that are designed for wet environments, like those with GFCI (Ground Fault Circuit Interrupter) protection. This distance and safety feature help to create a safer environment when using electrical appliances in proximity to water.
