Can I put an outlet near a shower if there's a glass door between?

Question

406.9(C) Bathtub and Shower Space. Receptacles shall not be installed within a zone measured 900 mm (3 ft) horizontally and 2.5 m (8 ft) vertically from the top of the bathtub rim or shower stall threshold. The identified zone is all-encompassing and shall include the space directly over the tub or shower stall.

Every diagram on this shows a tub or a shower with a curtain rod. My assumption is that a solid non moving peace of glass that goes above the shower head can be considered a wall and not the threshold.

Answer 1

Code was/still-is stupid here

The code doesn't define "shower threshold" explicitly and doesn't really define "wall" well enough to differentiate in the scenario you described. The result is that it is often left to inspectors to interpret and you almost always end up in arguments with them over it. I fought this issue and won... resulting in outlets next to the sink on the shower glass wall side of the vanity, but your mileage may vary.

Code for 2023 clarified it

In the 2023 code changes, they completely rewrote this section to basically say it's a 3ft radius from the closest edge of the shower/tub entry to the outlet. So under these rules you could place the outlet above the sink, touching the shower wall as long as the shower wall is 3ft deep (e.g. the door starts at least 3ft from the wall; outlet in the wall).
