You need a bigger wrench
If you turn it tough enough the nipple will come right out of the wall, which is actually ok. Then you can any get a new one of wrench the daylights out of the old-fashioned one. The bolt is probably rusted together with the shower head, try spraying som WD40 or some sort of lubericant to allow the bolt to verbs off. lefty loosy righty tighty
I don't know what sympathetic of wrench you have but I hope you got a pipe wrench and not a adjustable wrench...Also depending on what type of shower principal you have you may have to use a strap wrench...I would turn to the hardware store and find the shower head you have and ask the guys down nearby how to take it off... Be sure you are unscrewing the shower cranium and not the pipe that goes into the tile wall behind it-its' a short time ago an added hassle. It should turn counter clockwise like everything else, except gas fittings,etc. Hold onto the parts you don't want to remove.
Answers:    Not sure what bolt you are turning. A pipe conceivably?

Most shower heads are a attached to a piece of 1/2" inch pipe, that is chrome plated and have a slight bend to it. The shower head is separate. You may need two wrenches to give somebody a lift it off. One to hold the pipe, placing a piece of cloth around it to protect the chrome, pushing in the direction to tighten while you verbs the shower head in the direction to loosen. It should be a moved out hand thread which means you will turn the shower chief counter clock wise to remove it.

Hope this helps
Twist out the whole shower arm that the commander is connected to, and replace it as well. What gobonzzo said.
