When you're constructing a shower/tub, some serious waterproofing is necessary to make sure the above doesn't happen. There are a few layers but the first layer is this drywall board. The previous owners had two layers of drywall, while we plan on having one drywall (first) and then one concrete backer board (second).
Next time... what lies beneath. It's kind of like the skeletal structure of the shower/tub and we're doing reconstructive plastic surgery on it. Now... back to the Star Wars marathon on television.
