Drywall is typically a one-stop-shop for resilient interior walls — and it’s no wonder why, since it’s affordable, durable and stands up to smoke and fire better than many other building materials. But there’s one massive exception: it’s no match for especially moisture-rich environments. That makes finishing drywall around a shower flange or tub enclosure tricky, because using drywall as a backer for tile in these areas is likely going to lead to ruining both. Paper tape, too, should be right out — it serves as a food source for mold. Connecting the drywall to the shower enclosure, then, requires a different solution than finishing around a window, door or other detail.
