Battery-Powered Bathroom Fan: DIY 12V Fan Project with Faucet Power Supply Integration

Question

Hello,
Can any of you do a faucet-powered fan in the bathroom? I do not want there to be a cable from the hole to the socket (I have no way to mask it), and it is too late to lay a new cable under the tiles (the bathroom is newly renovated).
Can anyone tell me how to make a fan in the bathroom with its own power supply? can somehow deal with 12V fans?
God bless you in advance.

It makes no sense, the battery will run out quickly, the cost of operation is high. You can pull the cable from the lighting above the level of the tiles, unless you do not have one.
You can use a battery (at least 7-10 Ah) but you still have to carve a niche for its placement and replace it with a charged one or connect the charger.

Pull the cable up with a ventilation hose.

A little bit of information, a flat in blocks of flats, a tenement house, a single-family house? You can think about hooking up to the lighting.

vodiczka · Answer

What does it matter? If there is no other option, you can take out a few tiles and put them on so that there will be no trace. It was already about connecting to the lighting.

flat in a block of flats, tiles to the ceiling, nicely smooth ceiling. the closest (from the vent) power supply is quite far - on the opposite wall, it would also be a bit of removing these plates.
bathroom done a few months ago, so I really want to interfere with this freshwater as little as possible.

if there is any clever way I will gladly use it. and if not - somehow I will have to live without a fan ...

thanks to everyone for your interest.

And so I will ask: what is the finished ceiling? plaster, gypsum, plasterboard, PVC panel? What did you mask the connection between tiles and the ceiling with? Maybe here you can see the possibility of running a power cable? No problem

pabloben · Answer

ceiling - plaster and paint. connection of tiles and ceiling - grout. when I was doing the bathroom it seemed that a fan would not be needed. and now, when the shower is much bigger (previously there was a cabin), but the moisture does not ventilate ...

Maybe pull up the power from the lighting. Turning on the light in the bathroom will also supply power to the fan, there you can use a switch that you will turn on as needed.

pabloben · Answer

and it will probably have to be done. it will destroy only the ceiling and one tile above the fan ...

With all repairs, you should also consider whether you need to put new cables to power some device that was not there before or we plan to install it in the future. Most people only think about new plasterboards etc. and later topics arise in the most magical way to lay the cable so that it is not visible and God forbid not to damage the tiles or some plaster.

It should be checked whether the installation of the fan is allowed there. If it's a block, then there may be collective gravity ventilation there - and then it shouldn't be done.

Once you make the fan, think about how to turn it on. These will be more than one tile. The ad has been removed. Mod Chris_W.
