        adding a vent to shower Sign In/Join 
        I am in the process of tiling a basement shower and have concerns with poor ventilation. I installed tile-backer and painted the backer-board with UGL paint as a temporary measure while in-laws visited last year. Since then I have noticed a slight mold problem along the floor where the BB and concrete floor meet.
        There is a small exhaust fan outside the shower for a 10 x 12' room that seems to be working okay. As an option, can the the air return duct for the heating/AC system -- which runs up the wall separating the shower from the family room -- be used as a vent?

        Thank you for any info and suggestions.

        You can't do double duty with the air return.

        Since it's a basement, good chance you need to install a dehumidifier that can run 24/7. While your shower will add moisture (especially if the vent fan is not used) overall most basements will stay a little damp. Even a medium sized dehumidifier with a humidstat will keep things under control - as long as you have it rigged up to drain continuously.

        dehumidifier as suggested..
        sounds like condensation from under your floor plastic over the dirt under the floor
        as a vapor barrier

        dehumidifier hooks up to the hot water...drains into a y-branch tail peice,,under a sink. Wink
