How to eliminate awful stench in dorm bathroom?

I live in a dorm room and share the bathroom with 4 other girls. There is no ventilation in the shower room :( The shower is old fashioned, made of old ceramic tile and grout and is frankly disgusting. There is an undescribable stench in this bathroom that I just cannot beat. (especially after one specific person has a shower) When it is my turn to clean the bathroom, I bleach everything in sight, including the walls (which are painted concrete blocks) and the entire shower stall. I regularly pull out clods of hair from the drain (It seems they all have very long hair and I have very short hair, but they never clean their hair out of the drain) and I put the bathmat through a hot water wash. Today I replaced the vinyl shower curtain with a fabric one so I can throw it in the wash regularly as well. Is there any other suggestions on how I can keep it smelling better? I can't even breathe when I go in there. Maybe I could scrub the shower with baking soda? Or some kind of enzymatic cleaner? The bleach is a bit smelly as well. I use febreeze as well and it doesn't help much, it just chokes you more.
