Definition of showerhead in regards to bathroom height

[cyberwombat]

I think I understand but would like some clarification. IRC 2018 - defines a shower with min 30"x30" and 6'8" at showerhead. There are two graphics: https://buildingcodetrainer.com/residential-ceiling-heights-per-code/ but neither illustrates the in between - If my shower area was sloped - say 8' on one end and 6'5" on other and showerhead is on 8ft side that would be ok?

Yours would comply as long as all of the required
30" x 30" shower area is located within the 8 ft.
height area and provides the 6'-8" minimum height
at the shower head.

Well it's not all under the 8ft area... Am linking to an image to illustrate - as I read the code this complies but "at showerhead" is a bit vague of an area imo.https://prnt.sc/C-1oR4scMMpd - scroll down to see my image.

This post says all the 30" in front of showhead must be 80" though not sure if it's their interpretation or something written I have not seen

Ah found it - section P2708.
The minimum required area and dimension shall be measured from the finished interior dimension at a height equal to the top of the threshold and at a point tangent to its centerline and shall be continued to a height of not less than 70 inches above the shower drain outlet.
