Semigloss for bathrooms usually. "weather white" Behr Paint, "Alabaster" Sherwin williams paint are some of the whites we use. Trim in ultra pure white.

weathered white

no idea about whites but loving bm aura bath and spa paint!!

There are multiple schools of thought here - one is that you use the wall color, another is that you use the trim color, and yet another is that you use a completely different color altogether. There are no rules, really - it's personal preference and room dependent. As someone on the other side of this delimma, I chose to do my ceilings in my trim color on the upper level, and in a contrasting color on the main level (where we have stained wood trimwork). For both, I'm using a flat paint on the ceiling (as recommended).

Thank you all! Appreciate the responses.

I think a master bath can be more personal and relaxing ..even interesting…using a little color on the walls..

We went with the wall color on all of our ceilings. We used sherwin Williams alabaster for the walls and ceilings and high reflective white for our trim. I’m very happy with the continuity of using the same color on the ceilings. We went with a flat finish. Our wall texture (including ceilings) is a light orange peel texture. I think if I had a smoother wall texture I would’ve opted for either an eggshell or satin finish instead.
We did go with the sherwin Williams version of their bathroom paint in our high humidity areas as well and it’s been great.
