The bathroom normally sees that moisture load on its painted surfaces anyway. If you are concerned about what is left over if you turn the fan off as soon as you walk out of the shower, you'd either want to leave the shower door open after the shower or get a bathroom fan timer that keeps the fan on for a certain period after you flip the switch off. Also, if you ever need to replace the bathroom fan, you could get one with a humidity sensor and then it would be automatic.

The timer idea would be fine too if you left the fan off to keep the warmth while taking the shower and then as soon as you exit the shower to have the fan run until the bulk of the moisture is pulled out. Just keep in mind that you'll want a gap somewhere to be sure that you are actually moving air out of the shower area through the fan rather than just creating a useless suction with no flow. It looks like the space between the shower panes is probably enough but I can't tell what the depth is through the pictures.
