A 125-volt, 20-ampere outdoor receptacle in a bathroom must have GFCI (Ground Fault Circuit Interrupter) protection due to the increased risk of electrical shock in damp or wet environments. The National Electrical Code (NEC) requires GFCI protection for all receptacles in bathrooms, as well as in locations where there is a higher likelihood of water exposure, such as outdoors. This protective measure shuts off the electrical circuit whenever a ground fault is detected, significantly enhancing safety for users.

While it is true that weatherproof outlets, outdoor ratings, and tamper-resistance are important considerations for outdoor receptacles, the key requirement specific to the bathroom environment is GFCI protection. This is crucial for preventing shock hazards associated with moisture in these areas.
