Damp bathroom

    DIY Enthusiasts,

    I have a damp problem in my bathroom...every now and again I have to scrub the ceiling/walls. It's a smallish bathroom with no windows and a fairly ineffectual fan in it. Just wondering if anyone has any suggestions to alleviate this problem? Someone said to me that the electrics wouldn't be able to support a bigger fan :confused:

    By the sound of it I'd say you need a better fan, and it can't be true that the electrics wouldn't be able to support one. The fuse/MCB for the existing fan might be under rated, but it should be possible to run heavier cables through the same conduits and put in a higher rated fuse/MCB. Even a six amp lighting circuit could supply a 1 KW fan, and that's a fair bit of fan.

    NOTE before I get flamed -- I am NOT suggesting you do that unless you are professionally competent, registered with the relevant health and safety organisations, and are kind to dogs:D

    You can try another fan. Get a sparks to connect it to the light. If this does not work you might need to cut a hole in the wall to allow airchanges.

    I once seen a house with this problem and what they did was put a vent in the door.(Bear with me) it solved the problem, gave the air changes. Saved cutting a hole in the wall.

    However this might sound a bit simple. Is your fan extracting or blowing aire in

    It's a relatively new extractor fan, not sure what the power of it it. I'll take a snap of it and post it up here, see what you reckon. It's in an apartment block so no option to move it.

    Have to agree 100% with Joey, had the same problem at home on the ceiling of my en-suite, it was causing mold to grow in one particular spot. Installed a fan but still the dampness persisted. The door was sealing so well on the en-suite, not enough air could get in for the required air changes. Did not fancy cutting a hole in the door to install a vent so instead planed the bottom of the door about ¼” and that gave enough gap to allow air in. Also reinsulated the ceiling to stop the cold air getting to the back of the plaster board/ ceiling. Problem solved.
