Remodeling a bath - cost to move water lines a few inches?

Question

I am thinking about remodeling my 2 bathrooms, both of which currently have 72"-wide double vanities. The new vanities I am thinking of buying would need some of the water lines moved a few inches. For example, I would like to install 2, 24"-wide vanities (one at each end of where the 72"-wide unit is now) and put a piece of furniture in the now-open 24" space in between. The problem is that the 24" vanity has a drawer on the bottom and when I look at the current water pipes/connections, one pipe is coming in only a few inches from the bottom of the current cabinet - right where the drawer would be on the new cabinet. In the other bath, one of the water lines is probably 27-28" in from the left end of the 72"-wide cabinet, which means it is in what would be the space BETWEEN the new 24"-wide cabinets. (I hope all this makes sense!) So my question is, how difficult a job is it to move water lines a few inches up, down, to the right, to the left? And what might be a ballpark cost of this kind of job? FYI, my house is on a concrete slab (very unusual in New Hampshire) but the pipes are coming in through the wall, and all the plumbing currently works well. Anyway I hope I don't have to give up on remodeling my bathrooms! Thanks!!

Answer 1

There are plastic pipes with push-fit fittings which are compatable with existing copper, using 90 degree bends, you should be able to overcome any difficulties.   They stand up to high pressures and temperatures, so no need to worry.

Answer 2

That's not very difficult, just remove the drywall, expose the piping, then re-cut and solder the pipe where you want it. If you had the piping entirely exposed and the water shut off and drained from the system, a plumber could do it in about an hour and charge you maybe $150, or you can DIY
