Mold/mildew in shower

Eww...I can't believe the filth in our new bathroom and kitchen. My mom and I spent a good party of this afternoon scrubbing everything in the kitchen while FH ripped up the rugs and stuff and the kitchen actually looks great and clean.

Buut.....the mold and mildew in the bathroom just won't budge. It is about 2 inches thick in some spots!!! I tried straight bleach, clorox clean-up, soft scrub, some mildew thing from home depot yet some of it just won't go away! Any suggestions for something to kill it! I have been scrubbing the shower forever! FH walked in to make sure I wasn't passed out from the fumes! (I have window open and fan on)
Thanks
