I recently had my bathroom window taken out, cause it was in the shower, and leaking. Now it's a tub surround and wall. I know I have to go up on my CFM rating on my exhaust fan. But, meanwhile, when we take hot baths or showers we get condensation on the ceiling above the tub. So, much that it drips down.
And just this week, we have been having alot of snow in Massachusetts and very cold (sub zero) temps. I've noticed that on the outside of my house, right where the bathroom is...there is ice frozen onto my outside wall...like it was running down from the sofits and froze. Also, i noticed it was about 20 degrees out and the icicles on my gutters in that area were still dripping (melting).
My take on this is that I need more insulation in the area on top of my bathroom and probably other places. I think the heat from the house is going into the attic and melting the ice and causing condensation in the bathroom.
Any suggestions or ideas
