Need handyperson's opinion

[pop goes the weasel]

Ok I'll start at the begining. We started some major projects around the house. Not smart to do more than one thing at a time but it seemed ok at the time. I redid the bathroom, Everything but the tub ( we figure we have to cut it in half and push it through the window. The bathroom was built around it if you can believe that.) Everything is fine but the paint. I used washable bathroom paint and above the shower the humidity is making the paint bubble and when I wipe off the walls the pain comes off. There's dry wall underneath it that was painted before with no problems. Same kind of paint. My question is what can I use that isn't going to bubble above the shower?Any ideas are very welcome. Thanks

Did you put a coat of primer on the drywall first?

You don't say how old your house is, but I'm guessing the origonal paint was oil based. If you put latex (water based) over it, it will bubble and peel. You'll need to prime it with something like Kilz.
