Wet rated recessed light in shower
I haven’t checked the 2020 code but I have never seen a requirement for a GFCI over a tub or shower stall for a listed wet location fixture! Others have stated it is required on other questions but the last home we did for our company last year had 2 bathrooms with wet location fixtures over a tub/shower and a shower passed inspection and the inspector did check the listing on the shower stall because he had not seen that type of fixture before all receptacles require GFCI protection in a bathroom including a receptacle integrated into a luminary but luminary’s only do not. In fact GFCI protection is only required if the manufacturers instruction required it.
I am sure some of the internet only electricians will downvote
Code reference 410.10.D &amp; 208.a.1  in the code handbook the blue text also explains this.
