How to Vent a Bathroom Tub Drain How to Vent a Bathroom Tub Drain
If your bathroom tub drain is emitting bad odors, it's time to consider installing a bathroom vent. This can actually be a good idea, as it can take hot air away from the shower room, preventing moisture from building up around tiles, attracting mold, and it can also get rid of other bad smells. If you plan on venting your bathroom, you should be able to complete this task in a day without the assistance of a professional if you have basic home improvement skills.
Step 1: Locating the Vent
The first step is to determine the best place to position your vent. You would not want to put the vent into an area where the shower is being used, as this can mean that moisture settles around the vent, but on the other hand you do not want to put it too far away from the bathroom tub drain, either. If there is a suitable place nearby, you should mark this brick for removal. If not, then you might have to consider other options for venting your bathroom.
Step 2: Installing the Vent
Next you will have to fit the vent into the place that you have chosen. Knock the brick away from the outside using a hammer and chisel (or the tip of your screwdriver), and then take away the tiles around this area. You should also try and position the vent so that you only need to remove one brick, and a few tiles. Take your vent frame, and fit it into the location. You may need to add a layer of caulk around the edge to make sure that it is completely sealed into the wall.
Step 3: Adding the Vent Pieces
Once that is completed, you will have to fit the pieces inside the vent frame. In a bathroom, this will probably include a fan, and an on/off button. Some fans can be wired to turn on automatically when the light in the bathroom is turned on, but this would probably require the assistance of an expert engineer. Screw all of the pieces into the frame, and turn on once, just to check that it works correctly.
Step 4: Finishing
Before you finish the project you will have to ensure that the entire bathroom is properly caulked. This is the best way to prevent mold and other fungus from settling into the bathroom. Use a mold-resistant caulk, or one which is intended for use in the bathroom. Your vent should now be ready for use.
