How long until a bladder infection turns into kidney infection?

In brief: Varies

Many times an untreated bladder infection will just go away on its own.
Of course they usually go away much quicker if treated appropriately. The progression to a kidney infection (pyelonephritis) is variable but somewhere around 5% to 20%.
