Gurgling from the tub drain means air is being pulled through the trap. Here is the South San Francisco guide.
The vent
A blocked or undersized vent lets the drain suck air through the trap, which gurgles.
The partial clog
A developing clog in the branch line also causes gurgling as the water drains.
The fix
Clear the vent or snake the branch line to restore a clean flow.
The call
