If you have too much condensation on your bathroom ceiling and upper walls, it could be that the ceiling could do with more insulation. Condensation is always gonna occur on the coolest surface, but warm air rises, and holds more moisture in it.

You'll find that having a proper bathroom paint in a bathroom makes a tremendous difference. Inexpensive latex paints lose their hardness and adhesion under moist or humid conditions, and that results in them cracking and peeling, most often on bathroom ceilings (above the tub or shower) and high up on the walls (where condensation forms).

ugh I have this same problem. I installed one of those fans on the ceiling hoping that it would help the problem but I am still dealing with the buildup and mold...so annoying!

I have the same problem, and I need to install an exhaust fan. I have 18 inches of blown in insulation in the attic, but there is no moisture barrier. I dont know what to do

To remove moisture from the room, you need to have a fan big enough to change the air in the room every six minutes.
And the biggest part is the ductwork needs to be smooth, round, under 8 feet to the exterior....not into the attic.

Try this and it will work....no more moisture.

You can get a fan system that is based on a timer and will take the air from the bathroom out 3 times a day. This is a common problem with either a bad vent system or not enough insulation in the attic around that particular area. You need atleast 12" of insulation in the attic if you have blown in. I have a similiar problem around my skylight, but nothing near what your showing. Good luck!

My first response was "take shorter showers." What can you do in there for 10+ minutes anyway? Do you take a book too?

Kidding aside, condensation will happen with the excess of moisture. Either reduce the moisture build-up or accelerate the exhaust. Did you check to make sure there is a good seal around the vent? Get the biggest fan you can buy (look online). And, yes, check the insulation in the attic.

Good luck.

Oh boy a time warp!!
All the way back to 2009. Hmmmm.
The same still holds true, you need to vent it outside, and Like Call me villa said....save some water!!
