How to ventilate a 1st floor guest bathroom?
Question:I have a two story house with 2.5 baths. The .5 bath is down stairs and has no vent because it has a window attached. How could I go about adding a vent to this w/o having to just leave the window open? My master bath is the same but has access to the attic so that is no problem but the one downstairs is. Any suggestions?
Answers:
You really on have two options.. vent to outside or vent to ceiling/floor space. To vent to the outside there are vents available from Lowes and/or home depot to do this. However, depending upon what the exteriour wall is made of and what direction it faces, this may not be a good option.
You can also vent to the area between the first and second floor. Since this is a 'half' bath you will not be venting large amounts of humidity since there is no bathtub/shower. Therefore, just simply vent install a ceiling vent and let flow into the floor space.
Good luck and I hope this helps.
You can install a ceiling vent. Depending upon the direction of your rafters, you would either run ducting inside the ceiling to the outside wall with louvers that will open and close when the fan is on or off, or you will have to surface mount the duct against the ceiling. Either way you will need to penetrate the outside wall for your exhaust.
.I had the same downstairs bathroom configuration.
I installed the vent fan in the ceiling of the shower then vented it through the side of the house. You can connect the fan electric to a separate wall switch that can be installed next to the existing bathroom wall switch.
Of course you'll fave a lot of sheet rock repair to do once you are done.
