Hello!
Considering how to proceed with renovating a room - in this case, a bathroom - when you want the walls to be as flat/straight as possible to make later tasks like tiling easier. If the studs are not aligned with each other or are warped, what methods are there to correct the problem? Replace the stud entirely, add thin strips of some sheet material/list to get the right thickness, sand down any "excess"... what are your experiences?
