12 or 1.2 L?: 12 L of urine is unheard of and 1.2 L is possible. In my 46-yr study and practice in urology, the largest urine hold inside the bladder was 3.5+ L. Generally, a bladder holds some 0.25 - 0.5 L. So, either 12 or 1.2 L is too much. Is it normal? A detailed evaluation to assess your voiding pattern, check postvoid residual urine, urinalysis, etc. is needed. To assure such, see urologist timely.
