Bathroom Help please

oh'mike said:

First question---Is there more than one bathroom in the house?

This is sounding like a gut and re do.

Up date the plumbing --as much as you can---Is the house on a concrete slab or wood floor joists?

Next is electrical---new fan/light and duct--electrical outlet for the vanity--light opening?

Tell us more--pictures if you can--Mike---

Ok sorry I didn't add more info. The house is on wood floor joists. We have a finished basement below this bathroom. Yes there is another bathroom- stall shower.( Would like to keep the bath tub for as long as possible as daughter does not like to take showers yet).
All the light openings and vents look to be in fine places. The only thing I think I would change is that right now the light over the sink is the the soffit (see attached picture-sorry I am in it)and I think I would like it over the medicine cabinet but in order to do that I think I would have to remove the soffit which is probably a ***** to do. Picture is attached. I am fine with in the soffit.

So if I am understanding uou correctly. I can am going to have to remove the plaster on top as well as the tile on bottom? Or do I just have to remove the tile on on bottom? Sorry to be confused on this.
I have attached pictures. Sorry if it is too many. I have never had to do this before and want to make sure I haven't taken off more than I can chew. Am trying to do this all myself in order to save some money. Is there anything I need to know about before getting into this project? Thank you so much in advance.
