I'm installing sliding glass doors on a shower stall (aluminum frame with frameless glass). The aluminum side jamb vertical fit (on the shower head side) widens about 1/2 inch from bottom to top. What kind of shim material should I use behind the jamb (including the top screw of that jamb) to help level and reduce this gap.

I do plan to adjust the glass door runners to also help close this gap, but I am interested in the best material to use for a shim behind the jamb. I will also use a bathroom caulk to seal the vertical gap between the jamb and the tile wall.

Currently I'm planning on using the following as a support shim;
a 1/4" by 1-1/8" by 18" long piece of acrylic plastic with a hole drilled through it for the top jamb screw behind the side jamb and will caulk the sides and top edge of the jamb.

This will at least give a solid surface for the sliding door (little to no hollow area behind the jamb).

I have a frameless shower. The door is fix on one end to the wall and the other are hanging free.
Because of the frameless glass wall is tilted a little bit so the free end of the door rub against it.
What kind if shim can I use to correct the tilting and where can I buy it?

Where can you get the acrylic material for shimming? I have the same problem, aluminum frame but the wall is about 1/2 wider at the top than than the bottom

i had a similar issue while installing sliding glass door to a tub which had 55 in width at top and 53 1/2 wide at the bottom and the store guy sold me a standard shower door, My jamp had such gap to the wall at the top. My installer bought aluminium strip with jamb width and cut that strip to fit on the sides of jamb and adjusted to get the vertical angle that makes to plumb the jamb and screwed the two pieces to the jamb sides that fits to the wall. He did it on both jambs then my jambs stayed vertical for the doors and extra pieces screwed to the jamb got 55 inch at top and 53 1/2 inch at the bottom and stayed tight to the wall. This looked greatwith the best possible solution with large gap on the top.
