That picture is too tiny to be of help in seeing what you have. Can you retake it and load save it at full MB's when given the option, then load the image. It will be larger that way, I believe.

Thank you for responding. I hope this example is better. It's just an example. My ceiling isn't high enough to have the added finish detail on the header. So my question is related to a straight header with crown moulding above the shower door and then also crown inside the shower. My shower will be solid surface with a shower pan, not a bath tub and a glass door with a swinging door. Many thanks to anyone than can provide guidance on the viability of he header with a 7.5' ceiling and what I need to be aware of or consider during the planning stage and also what material would be suitable for crown moulding in a wet area. Many thanks.

in my experience with my bathroom, I don't get much wetness on the walls, because I have an exhaust fan with 2 vents, one in the shower with a light and the other elsewhere in the room. I get misting on the shower doors and tile walls only the paint I used was BM bathroom paint. I painted my ceiling in the shower, with tile to the ceiling. I would think that the plastic moldings you can buy and paint would be suitable. The product wouldn't be effected by moisture, and the paint is engineered to handle the conditions. As far as the header at the ceiling, I can't provide an opinion.
