Bathroom ventilation - to suck or to blow

[Rich]

Greetings,

I recently remodelled a small basement bathroom and added an exhaust fan & a shower.

Now after a year of use, I'm finding that I really need to tie it into my central heating/cooling system for my house to keep the air moving, and to ensure it stays an acceptable temperature. (The previous owners had never done so.)

Should I tie it into the output of my forced air system (blowing into the bathroom) or should I tie it into the air return? My thought is the former, however I have seen the latter done on several occasions (to continue venting the air from a bathroom even after the exhaust fan is shut off).

Thanks for any info,

Rich

Feed air in is the normal way to do it. I sure would not want the odors and or humidity forced through out my home.

Check your local codes. In my jurisdiction central air returns are not allowed in the bathrooms.

Geez, I didn't realize there was a difference.

Hi folks,

Thanks for the input - good points. Definitely putting in an output vent.

Appreciated,
