For the life of me, the more questions I ask, the more confused I get … there just doesn’t seem to be a concenus of opinion on how to build back our tub/shower surrounds.
Anyway, this is how we are going to finish the surrounds in the two baths of our house that are gutted right now, one at ground level (brick veneer exterior wall) and one in the basement (concrete block exterior wall) …
install encapsulated R-13 batts by Johns Manville in 2x4 framed wall (blackboard/brick veneer is on the oustide of the wall), attach green board (Mold Tough by USG) directly to the studs, attach HardiBacker over the green board, tape and mud HardiBacker, install porcelain tile over the HardiBacker
One other thing … the upstairs bath has a window opening in the surround … the tile that was there before failed and completely rotted out the window seal. What is the best way to protect the window seal this time around (we plan to tile it)?
Anybody bold enough to offer the perfect way of building our surrounds where they will stand the test of time and where moisture will not be an issue?
FYI … we live in Arkansas
