Sorry but I don't even know how to ask the question bc my knowledge of electrical stuff is very minimal... The previous owners had wall sconces in the bathroom that I do not want. I would like to not have any sconces in the bathroom at all. How do I go about closing up the wall where the sconce used to "attach" to? The wires are currently individually covered in the plastic thing. Can I just push the wires into the wall and close up the wall? What do I do about the wall switch? Can I push those into the wall and close it up too? Or do I need to call an electrician for this? Thank you.
