I believe that style baffle and a regular R-30 are rated for damp locations.
As for the shower spray issue, I believe it would depend on what type of shower head is installed, as to whether or not it would be subject to shower spray.
- An overhead rain-shower-whiz-bang head sprays straight down, and is not likely to be replaced with a wand.
- If a wand is present at the final inspection, I would say an inspector would be very justified in failing this installation.
- If it were a regular shower head seen in every motel across the US (and perhaps points abroad), then it should pass as is.
For me, I always install
a shower can over a shower, anticipating a wand. But, I have a wand and can't picture showering without one.
