moving a bathroom sink

Hi,
My husband and I are thinking of remodeling our Master bath. We want to put in a double sink, but in order to do so,we will have to move the sinks to another wall, because there is no room on the original sink area for a double sink. Will it be okay to move the sink to another wall, which happens to be an interior wall. Is it hard to move plumbing like that?

All things can be done, depending on how much money and time you want to throw at it.
Only a plumber on site would be able to put a cash number on it though.

To move pipes to other walls, would normally require moving pipes below the floor, and maybe in the walls below.
