GFCI Bathroom Code Requirements

Direct answer: Under the National Electrical Code, all bathroom receptacles require GFCI protection, regardless of distance from the sink. This has been a stable, long-standing requirement across multiple code cycles.

Bathroom GFCIs experience more failures and nuisance trips than any other location in the home, largely from years of accumulated shower steam and humidity.

What counts as a 'bathroom' under the code

The NEC defines a bathroom as an area with a sink and either a toilet, tub, or shower (or a combination). Any receptacle in that space needs GFCI protection — there's no exemption for outlets placed far from the sink.

Why bathroom GFCIs need more attention over time

Constant humidity and occasional splashes accelerate wear on the internal components far faster than in a dry living room outlet. It's one of the reasons monthly testing (via the built-in test button) matters more in bathrooms than almost anywhere else in the home.

Frequently Asked Questions

Does a half-bath with no shower still need GFCI protection?

Yes — any receptacle in a room meeting the code definition of a bathroom (sink plus toilet/tub/shower) requires GFCI protection.

Can one GFCI protect two bathrooms?

It's possible if they're wired on the same circuit with correct LOAD-side wiring, but many homes still use a dedicated device per bathroom for reliability.

Why does my bathroom GFCI trip more than others in the house?

Humidity and steam exposure are the leading cause of accelerated wear in bathroom-installed GFCIs.
