Need help installing bathrom vent fan/light combo

Our house is about 70 years old and has never had a bathroom vent fan installed. It has 1 light switch controlling one light above the vanity currently. I want to replace the light above the vanity PLUS install a ceiling vent fan with light. I want the new fan/light on the ceiling to be controlled by a different switch than the light above the vanity.

My issue is the power enters the bathroom and goes directly into the light fixture above the vanity then over to the light switch, If I understand correctly I cannot splice into that wire to get my power for the fan/light combo, Correct?

So if that's correct I have another option possibly. In the hallway outside the bathroom there is an outlet on a different line that the bathroom, can I splice into that wire for power for my fan/light? I would splice into that wire run it over to the switch then up to the fan/light in the ceiling. Would this work ok? Would it then make that wall outlet controlled by the new switch?

I bought 14/2 cable from local home store along with new light switches and outlet. Let me know if I need to switch to 14/3 wire or any other things I'm missing.

Thanks in advance for all help with this problem.

If power goes to the light first..... that's where you'd need to get power from.

14-2 is all that's needed. You'd take a piece of 14-2 from the hall receptacle to the fan/light switch. You could run either 14-2 or 14-3 to the fan light combo. I'd recommend 14-3 as in the future you could split the fan/light to two switches.

Thanks PJmax, ok if I run it from the hall receptacle to the fan/light switch would that then make the hall receptacle controlled by the light switch in the bathroom as well as the fan/light in the bathroom ceiling?

Or did you mean to say I should take a piece of 14/2 from the light fixture over to the new switch?

Hi, you will splice the new14/2 into the existing conductors, if itís not switched now then nothing will change.

How much more difficult would it be to put the fan part on a timer so that it will run for 10-20 minutes after we get out of the shower to help vent the bathroom. I see they sell a timer that you can set for 10, 20, 30 or 60 minutes and then it will shut off.

The timer would just replace the switch.

No problem at all, install a 2 gang box one switch for the light and a timer for the fan, this will require a 14/3 cable pulled between the fan/light and switch.
