I wouldn't; I estimate that you are in a 'cold' zone and in cold zones, we try to have the moisture that comes through the foundation walls, dry to the inside of the basement. We no longer put up 6mil plastic vapour barriers that only trap the moisture inside the concrete.
So if you had no shower at all, you'd have an insulated stud wall where water vapour comes into the basement. But now you have a shower down there, you want to continue drawing moisture into the basement but you have to manage it appropriately by installing a good fan that takes the excess moisture out of the bathroom and sends it outside.
That's the way to control water vapour; now as for physical water, waterproof the drywall - or whatever you make you shower walls from - by using a waterproofing membrane. These membranes slow down the transmission of vapour but prevent the drywall from even getting wet at all.
So 2 water things you have to manage: vapour and droplets.
Your local building codes may have something to say on the matter, so check it out.
Sure, you'll get a variety of opinions on this but the choices are clearer for those of us in cold zones, where, during the winter, we need moisture on the inside.
