I'm installing a Grohe showerbar and need to drill holes in the shower to install. I need to know if it's OK to drill off center as I believe the plumbing is at the center between the 2 valves up to the arm. and not have to worry about drilling into the plumbing.

Short answer: DON'T drill/screw direct above the centerline of the valve nor directly below each valve handle of a two-valve shower valve assembly.
First, to get your bearings, look at Figure 10 in the URL:
http://plumbing.hardwarestore.com/learning/how-to-replace-a-faucet.aspx
The pipe that carries the mixed hot and cold water between the valve assembly and the shower head is centered between them and goes up. Certainly if the showerhead is directly above the single valve or the center-line of the two valve handles.
So you know to avoid that location.
The two sides of the valve are, however, fed with hot and cold water lines. (those lines aren't shown in Figure, but you can see the fittings for them). If you can get into your attic or basement or crawlspace (whereever the pipes are run), look for two pipes (one hot and one cold when the shower is running) that are 6 or 9 or so inches apart. If by measuring from a common point (center of shower drain is good) they are centered under the valve, you're done. You know they go straight up/down vertically to each valve. So don't drill there either.
Caveat: If the supply lines come from above, they U-turn in the wall. So, for instance, they may be centered 16 inches apart in the attic and each turn in 5 inches as they U-turn to come into the bottom of the valve assembly 6 inches apart.

It is OK. to drill in the center, just go slow... pay attention where the water knobs are, remove one of them ,try the cold one , less chances of corrosion there so easier to remove , don't stop at the knob, also the face plate behind the knob. now observe the cooper pipe , now you know where the pipes are! stop there. now visualized the path of the copper pipes cold and hot.
next grab the power tool and drill slow. now if you have a single hot/cold knob , tough none of the above applies.

if you look at your two valves or knobs. the unit from the hot or cold runs down to the ground. the shower head is dead center of the hot and cold lines. they are usually flush with the framing. the two valves remember are running down and the shower head is dead center. you can drill either side of the shower line.

frequently b till i recognize that that is in all likelihood a pretend alarm. One paying for centre in my section has its alarm bypass off quite frequently. i'm able to't keep in recommendations the precise reason even if it really is a properly-known difficulty. I have lengthy gone out with some people yet after slightly found out that it replaced into in basic terms pretend. someone that works interior the mall suggested it replaced into elementary and for this reason a large style of people do not go away. that is totally loud inspite of the actuality that. If a is the norm then it really is extraordinary. lots of the time I supply up what i'm doing and head for the go out/the front way. That looks widespread to me.

yeah the pipe is ran straight down to the faucet area and you would know if you were starting to drill thru it it wouldnt go anywhere fast also you can get some stud finders that can detect electric and pipes kind of expensive though
