How Many Gfci In Bathroom
Click to Enlarge All 125-volt, single-phase, 15- and 20-ampere receptacles installed within 6 ft. of the outside edge of the bathtub or shower stall must now have GFCI protection. 
Code Change Summary: A new subsection was added to require ground-fault circuit-interrupter protection (GFCI protection), for 125-volt, single-phase, 15- and 20-ampere receptacles installed within 6 ft. of a bathtub or shower stall.
If a hazard exists and GFCI protection is required for 125-volt, single-phase, 15- and 20-ampere receptacles installed within 6 ft. of any dwelling unit sink, then the same hazard exists within 6 ft. of a bathtub or shower stall.
Now GFCI protection is required for any 125-volt, single-phase, 15- or 20-ampere receptacle installed within 6 ft. of a dwelling bathtub or shower stall.
All 125-volt, single-phase, 15- or 20-ampere receptacles installed in a bathroom must have GFCI protection even if a bathroom receptacle is 100 ft. from any sink, tub or shower. Section 210.8(A)(1) requires GFCI protection for these receptacles any time they are within the envelope of the bathroom, regardless of distance to the sink, tub or shower.
Outside the bathroom, possibly in a hallway, or bedroom, if there are any 125-volt, single-phase, 15- or 20-ampere receptacles within 6 ft. of the shower or bathtub, they now require GFCI protection even if they are not within the envelope of the bathroom.
