Which type of electrical receptacles should be used in bathrooms?

In bathrooms, it is crucial to use GFCI (Ground Fault Circuit Interrupter) protected electrical receptacles. GFCIs are specifically designed to protect against electrical shock in areas where water is present, such as bathrooms, kitchens, and outdoor spaces. They work by constantly monitoring the flow of electricity and can disconnect the circuit if they detect any imbalance, which can occur if a person comes into contact with water and an electrical source. This makes GFCI protection essential in reducing the risk of electrical hazards in wet environments.

Using GFCI receptacles meets safety codes and regulations that govern electrical installations in bathrooms, ensuring that homeowners are protected from potentially fatal electrical shocks. The other options may provide conditions or suggestions regarding receptacle placement, but they do not offer the same level of protection against electrical faults as GFCI receptacles do. Therefore, the requirement for GFCI protection is the most critical consideration when selecting electrical receptacles for bathrooms.
