Gap between shower metal frame and tiled wall

[Kinetic]

Hello and thanks for your time.
When the shower metal frame (that will hold the glass wall) is placed plumb along the tiled wall, you can see that the tiled wall is uneven. The top and bottom touches the tile wall but in the middle there is a huge 2cm gap between the metal and wall. Basically the wall is concave.
Apart from an incorrect tile job, Is there some kind of a trim, gasket, liner that can fill this unsightly gap so that it looks good and does not allow water to flow through? What if I screw on the metal frame tighter in the middle to help close the gap and then I may be able to silicone it. The glass wall then would fit inside of it plumb and level but the metal frame would be slightly bent inwards. Please help

Don't even think of bending that frame. Your problem is bad enough. There is a multitude of plastic, metal, ceramic corner material along with caulking that can be used. It's up to you as to how good it will look when you're done. Look on the internet or visit a big box stores to get a feel for what can be done and how it looks.

I wouldn't bow the metal by tightening the screws. If anything, I would use shims like toilet shims behind the metal, so it is secure then figure out some trim to hide the sin.
