I painted the spare bathroom first as we could take showers in there while we waited for the paint to cure in our master bathroom and vice versa. What most people don't realize is just because paint is dry, doesn't mean it's going to hold up to water and other forces until it cures out. So we tried to wait as long as we could before coming back to it. Which is good thing we have two bathrooms. Like I mentioned before this color (which I'm sure is New Penny 3001-8B by Valspar) was in both bathrooms and in our bedroom when we got the house, I just didn't like it. I also saw that they used a really cheap contractor grade and you could tell it wasn't holding up despite having a semi-gloss finish.
We used the same can of paint, Olympic One latex in a semi-gloss finish. The color is Grandma's Sweater (787) by Benjamin Moore that we had color-matched into Olympic's paint.
I also worked on the trim of the bathroom. While it's hard to see in the first photo, the baseboards were dusty and flat and just plain ugh. Now they are white, shiny, and clean due to the high-gloss white finish. We also replaced the bathroom curtain.
