Do I need to plan the framing depending on the position of the wall to glass clamps for a frameless shower

framing

My design includes a frameless shower glass enclosure
This is for a corner and it will have two fixed glass panels

I am now building the framing and I am trying to understand if I should provide support in the framing for the clamps that will support panels

These will not be floor to ceiling pannels and no support rods are planned as they will be ~40" and ~30" wide

I would have two clamps on the wall and one on the shower base for each panel
My plan is to run 2 horizontals made of a 2×4 segment that will be screwed to the studs as seen in the below picture.
My problem is that I do not know yet what shower panels I am going to get and what would be the best position for the clamps

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.
