Painting over flat paint in bathroom
 
Ok, I'm sure this has been answered before, but I just want to make sure that I'm doing the right thing...our house is 5 years old and we have been living in it for approx. 4. I decided 2 months ago that I wanted to paint our guest bath. Not knowing ANYTHING about paint other than what color I wanted, I chose a cheap (I know, I know) flat interior paint for the walls--we didn't re-paint the ceiling. The walls were originally painted a flat off-white color--I went for a medium brown--called "Ottertail"--we used 2 coats. Now, 2 months later, the paint is starting to discolor around the shower--blotchy darker areas, and I hate how chalky the flat paint looks. Obviously most of the problem is from the cheap paint and the humidity in the bathroom. From reading other threads on here, I know now that I should've used a paint made specifically for bathrooms and NOT cheap paint. So, what's done is done, but I want to fix it, because I am very disappointed in the result! First off, do I need to re-sand or re-clean the walls before re-painting? Secondly, do I need to use a primer over the flat paint, and if so, what is recommended? Third, what is a durable brand of bathroom paint (I don't plan on re-painting again for a long time if possible)? Fourth, do I need to go with a lighter color (I'd say it's about the color of chocolate milk now), and if so, would I need to prime it to cover the brown? Thank you for any help you can provide!!

I would clean and sand just to be on the safe side

You also might want to use a quality primer also just to be safe
(the bathroom is the worst environment for paint to adhere, and you've got a few layers of cheap stuff on there right now, best to stack the deck in your favor)

Benjamin Moore and Sherwin Williams both have excellent Kitchen & Bath paints
BM's Aura also works great in this tough environment
All are "self-priming", but I'd still hit it with a coat of primer anyway, as we're not really sure of the quality of coatings thus far

many bath paints are self priming. The reason is the mildicide will move to the surface from the primer after it is exhausted in the top coat. I would use Zinsser's Perma White which you can tint to any color. Just clean with TSP and rinse first.
