How much will it cost to add a master suite including bath onto my house?

Question:I live in Dallas, TX in a 3250 sq ft 1969 ranch-style house and have been looking into updating my master bath. However, every contractor and designer I've talked with is having a difficult time getting a bathtub & shower to fit as well as enclosing the toilet in it's own private closet without moving it, which will require drilling into the slab. I also wanted to update the closet storage, which is poorly designed but probably adequate in size. The estimates I have received so far range between 30k and 50k for the bathroom project and may include the closet on the upper end. It occurred to me that I may be able to build a master suite up instead and use my current master bath and room as a game room and pool bath since it is adjacent to the backyard. I realize it may cost more than 50k, but it will also add sq ftg and value to the house, right? If anyone out there able to provide an informed & thorough answer to this question, I certainly would be appreciate it.
