Thanks Everyone! I will check out the solutions. I ended up doing the following:
-creating a glass shower wall
-inserting a shower door (my own template) into it but I did a slim casing, removed frame, door jamb, threshold, sash etc so it was less clunky.
-I added in a window on either side and made it the full height and width of the panel, and also removed sill, frame, slimmed down the casing to 1 inch and just minimized everything.
