So I have read a ton of stuff on here about basement insulation, framing, and showers. All of it has been very informative, but I can't seem to find out whether my plan is going to work or not. Here's the situation: I am building a bathroom in my basement, 1950's ranch in CT with concrete block foundation, minor weepage at the concrete floor/wall intersection when it rains. I plan on insulating the concrete walls with 2" xps, then framing a 2x4 wall directly against that. I plan on having one of the shower walls be directly against part of this 2x4 outer wall, and it will be waterproofed with either kerdi or hydroban...not sure which yet. Anyways, I want to insulate the stud bays with roxul, but I am not sure if I should do that for the shower wall. Will these create a moisture problem in that section of wall? In case it helps, I will be putting foam board under the PT bottom plate of my walls to also keep any moisture from wicking up. The weepage should be solved once I re grade the outside yard to install a paver patio. Thanks in advance for any advice!
