My bathroom looks like this:
The problem is that I face some mild humidity issues (on ceiling and tile grout), as it is difficult to extract air after having taken a shower.
Indeed, it happens that the door is virtually air-tight.
This makes that none of the ventilating strategies below is really effective:
|1||on||closed||closed||Fan is not powerful enough to suck enough air through the door, so the flow doesn't seem sufficient to prevent condensation on walls and ceiling.|
|2||off||open||closed||Usually not sufficient enough, plus is a bit of an issue in winter as the dormer window can't be open/closed easily (too high); plus leaving it open constantly isn't very pleasant in the morning).|
|3||off||closed||open||Humidity goes in the flat, and low air circulation within the bathroom makes that there is still condensation.|
|4||on||open||closed||The air extracted by the fan… is mostly that that just entered through the window, so it's not effective.|
|5||on||closed||ajar||Works, but the sound of the fan — despite being not very loud — is bothering as the bedroom & home office are located right in front of the bathroom, so still not optimal.|
|6||off||open||ajar||Most effective solution, yet leads to draught and slamming doors ; plus isn't really possible during winter months.|
So I think that strategy #1 would be ideal… should the hallway ￫ bathroom air flow be greater. I don't think a more powerful extractor fan would be of much help in the current configuration… plus it's likely to be even noisier.
- Would trimming the bottom of the door (to let more air from the hallway in) be a good idea?
- If so, how much should I trim?
- Would a circular saw (with a guide) be the right tool to do it?
