Rotten Wall Behind Bathroom Enclosure

Allow the wood and wall cavity to completely dry.

Rotten wall behind bathroom enclosure. Cover the wall cavities with a rigid air barrier or other supporting material to prevent cavity insulation from sagging and to create a continuous thermal barrier. Fiberglass and acrylic tub and shower enclosures come with a flanged edge that attaches directly to the wall studs and the proper way to hide this flange is to install drywall over it. Then pull the tile and small squares of drywall out together. If any of the wood studs appear wet and moldy you can clean them with a water bleach solution.

Position the cut drywall sheet on the wall. Leave a 1 8 inch gap between the bottom. To remove tiles that won t budge reach into the wall and use a utility knife to score the drywall from behind. Make sure the bottom side edge of the drywall sheet extends down over the thin lip of the tub s mounting flange.

If you find that the wood is rotted you will need to replace it. Install insulation without misalignments compressions gaps or voids in all exterior wall cavities behind tubs and showers. Any insulation that is wet or moldy will also need to be replaced.
