When you have one fixture backing up into another, the clog is downstream of both of them. I'd try snaking from the rooftop vent (if your snake is long enough) or try to find a cleanout cap you can open and snake downstream from the tub as far as you can.
I've never had much luck snaking through traps. If you can't find a cleanout, you could buy a new toilet wax ring and pull the toilet and snake from there.
Anyhoo, your toilet won't back up until the water level in the tub rises several inches above the floor level. So your problem just isn't bad enough to show up at the toilet... yet.
