Removing a branch circuit

[jcostanz]

After quite a bit of water damage to a bathroom in a 1939 circa house, I want to run a anew circuit with ground to the bathroom. The problem is the light switch and outlet in the bathroom are supplied from the light in the hall. The wires are soldered together in the light box. What is the best way of removing these branch circuits. The plaster walls have been removed from the bathroom.

The existing wires are only 2 conductor cable.

Thanks

Are you experienced with working with electrical? Do you have a fuse panel or a breaker panel? Is the bathroom over a basement or crawlspace or directly under the attic? If you're removing a circuit, the first thing to do is to disconnect it from the main panel.
You need to check with your Building Inspection Department regarding permit and inspection and local code requirements.
If you're re-wiring a bathroom, you also might want to consider adding an exhaust fan.
If local code permits you to DIY the wiring, we'll be glad to help with suggestions, but we need more information of what you're working with, the general layout, etc.

Here, any new wiring has to be brought up tp current code. This would mean that the entire circuit would have to be rewired. This is common in older homes.
For your safety, you might want to consider rewiring the entire house. Bad news now, more expensive later, adds to resale value.
