Small Corner Baths I Have A 2 Bedroom Home With A Small Bath. Should I Expand The Bath Into The Small Bedroom?

I have a 2 bedroom home with a small bath. Should I expand the bath into the small bedroom? - small corner baths

The bathroom is very small. I was able to extend the kitchen into the existing bathroom by wardrobe is limited. After the small room, which is really small, in a bathroom bigger and better. Could build a room on the ground floor in order to compensate for the loss that the above or bathroom could build a stairway, put a corner shower small bathroom upstairs, but that would mean with the plumbing in the sub - soil, where they exist.
