That's what I was thinking! What would something like that cost?

I do want a make up area so the sink would be off to the left?

Find an inspiration picture/s to illustrate the level of finishes you want and contact a contractor to get a price. Not moving the plumbing will save money, but depending on where you live and having the contractor do all the work and purchase all the items, I would guess at least $15k+.

Are there any windows in the space? I see what look like doors to a closet and bedroom. Are they pocket or swinging doors? What direction do they swing or slide? Do you have a style in mind?

No windows unfortunately, door swings into bath. I'm looking for a marble white transitional look

Swings towards the closet
