Will sealed bathroom door allow fan to vent bathroom?
« on: January 01, 2008, 07:18:32 PM »
Planning to soundproof a guest bathroom for privacy. This will require a solid-core door with good sealing around it, which will completely seal the bathroom. Will this cause problems with venting the room (80 cfm vent fan) when the shower is running? The door (and plumbing I guess) is the only source for the vent fan to draw air from. Will even a well-sealed door leak enough to pass 80 cfm?

Searched the forums and did not see this question posted. Thanks for the help.

It will cause problems.  Without an adequate supply of 'make-up' air to replace the exhausted air, the fan motor will be under a lot of strain and will burn out within a couple of years (give or take, based on usage).

I give you kudos for soundproofing, but you might be going a bit overboard.  Try the door without any seals first and judge how loud the noise is.  Then add them if necessary. 

And remember, the bath fan itself is a great white-noise generator that will mask some of the sound.  Maybe you could wire it up so it comes on when the light's on.  You could solve a lot of problems right there...
