Currently the way the bathroom is set up is the his/hers sinks, shower, and whirlpool are in one room and there is a separate small room for the toilet.

The only exhaust vent is in the toilet room. Terrible setup really.

Over the shower there is a light fixture. My question is is it possible to use the current wiring for that light fixture for an exhaust fan/light unit.


May be a dumb question and sorry if so.

Thanks.

All depends on what wiring is currently up there and what is required of whatever you go purchase.

If it will be a unit that simply comes on with the light then yes, no new wiring would be needed. If you want to control the vent and the light independently then you will need to run another wire to switch the power lead.

Sure why not. Where are you going to vent the fan though? Hook it to the toilet or just have it blow into the attic?

1. make sure you cut a hole in the roof and vent that thing out of the house (per codes)

2. i'd rather install a broan heater (electric coil with a fan) to keep the bathroom warm in winter and help remove excess humidity.

I will. In fact i dont think the vent in the toilet room is doing that now. Which is pretty aggravating. So I'm going to fix that as well.

But i was going to go through the soffit and not the roof.

Preferably i would want it to be a seperate switch but i've already accepted the fact that it wont.

If you install one with a heater it may need an additional breaker. It depends on what is on that circuit.

I did it last year. Replaced my light with an exhaust light and tied that into my already existing bathroom exhaust. Easy as pie. I used a baffle too if I remember right.

You want me to come do this shite Nap?

Serious? You really should vent up through the roof.

Check out the new vent fans inside of a recess light trim. It will probably require some sheetrock cutting in order to install but once its is in it will look great.

Why are there not fans in hotel room bathrooms? Whenever I want to blowout, I have to go to the lobby.

That sounds correck.

I removed an old one and installed a new one but there were already 3 switches on the wall so I didn't have to do anything else with the wiring.

FYI, the instructions said it would be about an hour or two job...took me most of the weekend. The attic space where the vent was going was very cramped because it was so close to the edge of the roof. Lots of hollering at the old lady to fetch me tools through the hole in the ceiling. Also, I had very little electrical experience and didn't want to fry myself. Be sure to turn off power at the breaker.

Have fun!

Tie that shite into the existing exhaust. Don't run a new one.

Soffit vents are fine for bathroom exhaust. I'm pretty sure on heated exhaust (oven vents, heater vents, etc..) ned to go through the roof.
