We have tub units that are on outside walls with insulation behind them, no dry wall. They are finished with drywall around them. All plumbing is on inside wall. I think condensation from the cold outside wall is getting the wall wet and making it bow. I'm wondering if any of you country folks has seen this and did something about it. I want to add insulation from the outside wall and reseal. [img]/forums/images/icons/confused.gif[/img]
