   If there is a mudbed behind the tile, it probably is never really drying out. Do you leave the door open when you are done to let air circulate? Not a whole lot you can do. This is why Kerdi is such a great product, only the thinset and grout can get wet, so it dries completely and quickly.

   Same thoughts as the other poster.  If you have drywall behind the tile (which was common then) the drywall is probably always damp and the grout never dries.  If this is so, eventually you'll have to rip out the whole thing and retile it.  But if the wall is sound now then cleaning and airing it out is the best answer.  A capful of bleach in a quart of water, letting it soak in the grout, and a brushing with a soft toothbrush can remove the mold.

   Do you keep the shower doors and the door to the bathroom open whenever the room is not in use?

   Do you have a vent fan and do you use it? They can help. You can clean the grout with chlorine bleach. You can also re-grout which will help keep water from getting in. Use a sealer on the new grout.
