I am not sure about that fitting, is it a push fit at one end? Usually your feeds will be fixed with clips to the stud work behind the shower so as to reduce movement on the pipes when the controls are turned off and on. Pipes under pressure can flex or move and need to be secured. You might want to alter things if you are going to be leaving the bar or controls fixed only to the tiles.
Have you done work like this before? I ask because if not you might want to consult a plumber, shower bars etc have different fittings that may need to be fitted depending on your heating system.
