Our master bath doesn’t have an exhaust fan and I’d like to add one to help with the humidity. It’s the primary bathroom of use upstairs and the 2nd full bath is on the other side of the wall.
Can I use a splitter to tie the other bathroom’s exterior vent to the new exhaust? If I did I’d put the splitter closest to the vent to help prevent blow back to the other bathroom. They’re both smaller bathrooms (50sqft and 100sqft).
Or is it just better to put it on it’s own exhaust vent?
Thanks for the feedback. Honestly both routes are probably the same amount of work so maybe I just get done with it and do a new vent so I don’t need to worry about it when it comes time to sell.
