Interior first floor bathroom needs vent fan in Middle Tennessee
Lu Ann

This house was built before bathrooms existed inside homes and this bathroom was remodeled about 21 years ago. I don't know why the contractor didn't put in a vent fan then, but he didn't and I didn't know one was necessary at the time. I've learned a lot about houses since I bought this old thing. There are 3 other bathrooms in the house, new since 21 years ago, which are vented. Originally this was a guest bath and used very seldom, but not the family has grown and this is now a family bathroom and the shower is used quite a bit. This bathroom has all interior walls with no access to the outside through a wall. It is in the center of the house on the first floor underneath a large upper room so there is no wall that runs up to the second floor room next to this bathroom. The laundry room is next to the bathroom and the dryer is vented under the floor via a long pipe that terminates on the outside of the house. Could I put the vent in the floor and run the duct under the house to the outside wall? Could I put the vent in the floor and run the duct to the dryer duct and send air and moisture out that way? Obviously I want to avoid ripping out walls, ceiling and floors for this project. I also don't know who to call to discuss this project with -- electrician, HVAC contractor????? Thanks for any ideas you have. I live in Middle Tennessee about 50 miles from Nashville, 20 miles from Murfreesboro. I'd like to get the bathroom vented before too much damage is done from mold and any thing else that might go wrong.

You must be close to where they make Jack Daniel's - which is a good thing...

Who to call? call an electrician and have him install a powerful unit (look at panasonic fans). I'd guess that a vent similar to the dryer's will do the job.

I don't see any reason to not put it in the floor, but I think it might be better up high on a wall and then run a duct down from there through the floor. It can be done with only a little wall tear out. If the contractor can access the exact location of the wall from under the house, he may be able to cut out the sill plate for the wall and pull a duct from the fan without tearing up any of the wall. The only hole in the wall will be for the fan itself.

The exhaust vent will work better mounted high, since the 'steam' from baths or showering is warmer than the ambient air and will rise. If you've got a 2X6 plumbing wall (probably not in a house as old as yours) a wall-mounted unit can be run without opening the wall inside the house. Anything will be better than nothing so do what you have to but get the room vented somehow.

As a AC powered unit, there are electrical code issues to be dealt with (distances to wet areas like sinks or tubs) so an electrician with a good imagination for running the vent line is who to call- they will know how to do this safely.
