A plumber is unsure how to set the optimal valve depth for a shower valve to match tile thickness, finding the manufacturer's recommended range too broad.

Manufacturer's installation manual gives a wide acceptable depth range (2-3/4" to 3-1/2") but doesn't help the installer calculate the exact depth based on their specific tile assembly thickness.
