Hi Everyone,
I embarked upon my first ever painting project in my house with my remodeled bathroom. The guy who remodeled my bathroom ran out of time, and I ran out of cash, so I decided to repaint it myself.
About 20% of the surface area that I painted was new sheetrock and texture, whereas the remaining 80% was existing (another corner we cut leaving all the existing lath & plaster in place and just putting new dry wall in where we had to knock out the wall to get to the plumbing and also to blend it in with the tile).
I put 2 coats of KILZ latex primer on the entire walls and ceiling. I then painted it with Ralph Lauren semi-gloss paint. The color is an off white color called TUOLOMINE or something like that.
Now, there are water stains on the walls whenever I take a shower. I always shower with the bathroom door open and there is also a large window in the shower which i leave open to keep the bathroom aired out. Unfortunately, water still builds up on the ceiling and walls, and then it STREAKS down the walls. It's very annoying, and it looks like even after drying with a towel some of the streak marks remain.
What causes this? Did I use the wrong kind of paint? How can I fix this?
Any help would be greatly appreciated! I am starting to wonder if I should just leave everything to the pros and keep doing what I do best... Fix computers!

You need to install an adequate ventilation fan to remove the excess moisture when using the shower. Water should not condense on the walls and ceiling.
Do the marks remain after the wall has had a chance to dry?

Yes, the door and window will help, but as Chris pointed out, an exhaust fan is best. Steam/heat rises, and has no where to go once it hits the ceiling, so it condenses and runs down the walls. A good semi-gloss should have been suffice, but its possible that the paint wasn't fully cured (some take up to 30 days) before the first shower, and the sheen is showing the paint as it rewets.

My neighbor who has exactly the same house as me put an exhaust fan in his bathroom, and there is still a ton of moisture build up in his bathroom as well. In fact, he closed off his window and just did the exhaust thing, and I think his bathroom gets more moisture then mine does. The problem is the size of the bathroom, it's only 6 feet x 7 feet, so it's REALLY small, and thus the moisture really builds up fast when taking a shower.
Honestly, adding an exhaust fan would probably cost me a minimum of about $1000 in labor to install because of all the dry wall that would have to be torn up and then re-done... Electrical... And plumbing to tap the exhaust vent into the existing plumbing ventalation system... Or I'd have to poke a hole in the roof and vent it out that way and that would definately expose my home to more roof issues. I don't feel comfortable doing all that myself.
Someone at work told me to try using an oil based paint, and do 3 coats of it, instead of latex, and that will last forever in bathroom and kitchen environments.... Seems to me like it would be worth a try, but I'm new at all this, and don't want to waste my time. Any comments on oil vs latex?
