Do I need to plan my framing depending on the position of the wall to glass clamps for a frameless shower?
This blocking to support the glass panels should be 2x6 or 2x8 and should be placed with the wide side facing the room, but in the plane of the studs (interior side).
You should also place 2x8 blocking inside the walls of the shower for later placement of grab bars in the shower. This should definitely be on the long wall and the back wall. There should be grab bars on the control wall, but you have to be carefull placing blocking inside the control wall to insure it does not interfere with the water supply pipes.
