no problem since air moves. When air is stagnant, or 99% stagnant, mold grows , assuming it has mold food like paper on drywall or old soap. So you will be OK.

We have a pocket door between the toilet compartment and the rest of the bathroom. No problems.

Moisture should not be a problem. Just remember that the wall with the pocket, if it is a normal thickness, can't have outlets or plumbing in it. Also make sure that the person who installs it really knows what s/he is doing. A door that jumps or drags on the track is so annoying you will never use it.

Make sure the contractors don't nail the trim and baseboards or hang hooks through the pocket door. Don't laugh, Ive seen it done.

I had pocket doors and no problems. I loved them as they used NO floor space in my small bathroom. I did not keep the doors closed when not in use so that might be why I never had any moisture problems. I could not vision your scenario but if you are putting a pocket door in it usually has to be framed specifically for a pocket door or so I have been told.

Thanks everyone. I appreciate your comments.

The bathroom is a total gut job, moving all the plumbing around to make it more functional. More expense than I wanted, but with 3 daughters sharing it, I figure it's worth it in the long term. We have pocket doors elsewhere in the house, and I absolutely love them.

The pocket door will be in a wall that will indeed have plumbing on the tub side. I'm figuring, based on what GC has said, that the wall will be about 10" thick. Might not be the optimum situation, but I'd rather have that than put the plumbing on the other end of the tub, which would place it in an outside wall. If I can figure it out, I'll post a floorplan.

We won't be starting this project for at least another month, but I'm kinda OCD (or maybe anal!) about things, so I'm trying to work out every last detail ahead of time.

I have a pocket door in the exact place you want to put one and we have had no problems at all. We do have a window in the shower area, but we rarely open it in the winter and we have had no issues.

Regardless of which side of the opening the door sits, the wall will have to be the same thickness thoughout. However, the non pocketed side of the door could possibly have some recessed storage. I really like pocket doors and try to integrate them in designs wherever they might make sense.

With all that bathroom use, a good bi-fold or split doors would be my solution. Quicker to operate, too. I wouldn't want moisture in the pocket either, esp. added to all the dust, etc, that will collect in the pocket. Ugh. (more sound gets around pocket doors anyway)

How about a thicker wall (and thicker jamb) with a wide opening, allowing room for the door halves within the jamb when open? You could even put in some recessed cubbies in the wall for toiletries.

Just a thought.
