We are talking with our contractor about installing a fan for our windowless bathroom, and have a few concerns. Our bathroom is located far away from the building's outside wall, so the only way for them to install the fan is to attach a short hose from the bathroom vent that funnels the air into the wall space behind the medicine cabinet. Our contractor assured us that this space leads up to the roof and since there's a roof vent, it would be OK.
We were concerned that the steam from a hot shower that would be funneled into the space may promote mold or condensation inside of the wall space. There is also some wood within the space we are worried may be damaged, but both our contractor and electrician assured us that it wouldn't. Does any one know if this set up is safe to do for our building? Our super happens to be away so we can't ask him. Thanks!

Midtownite,
Most building will not allow you to do that, you should check with the management company

Thanks Primer for your advice. We are going to hold off on the fan for now, and when our regular super comes back we will ask him his opinion on the matter.

Since there's space between your ceiling and the roof, is this a rowhouse?
Whatever it is, your first idea is right: you can't exhaust a bathroom into another room, or between the walls, or anywhere inside. You need to duct it up onto the roof.

In the absence of a vented fan, just keep the door open and position one of those Vornado fans near the door.

Hasn't bathroom ventilation been code-required since 1908 or so? Window or mechanical

Thanks for the information everyone. It's a small bathroom with no windows. The previous owners did lower the ceiling for some reason or other and it's on the 4th floor of a 6 floor building. I've taken a look at 2 other units in the same building and neither had vents or windows in their bathroom. Maybe in the future I'll check with the management company about their bathroom vent policy and see if I can find a contractor who will do it right for a reasonable price, but for now I can take showers with the door open since I'll be living by myself.
