Are GFCI-protected receptacles permitted to be installed within a tub or shower space?

GFCI-protected receptacles are not permitted to be installed within a tub or shower space due to safety concerns. The National Electrical Code (NEC) clearly outlines that receptacles should not be installed in locations that are considered to be within the boundaries of a bathtub, shower, or other wet areas where water is present. This restriction aims to mitigate the risk of electric shock, which can occur when a person can come into contact with water and an energized electrical source.

While GFCI devices are designed to prevent electrical shock by interrupting the circuit when a fault is detected, the fundamental safety principle is that an outlet should not be located in an area where water could come in contact with the outlet or its cover. This ensures that the risk of shock is minimized, even in the event of equipment failure.

In residential wiring applications, adherence to these safety codes is important for ensuring the safety of occupants. Thus, the installation of GFCI receptacles within a tub or shower space is prohibited, reinforcing the necessity for safe design in locations with high moisture content.
