I had the same problem with an older type tub with 3 handles near the tub outlet. The middle handle, the diverter, used to divert from the tub outlet to the shower, needed washers. That's the simple answer. Mine had other issues, too. Just replace the washers. I did the valve stems too. About $8 each for hot and cold, and $15 for the diverter.
Sometimes a special socket is needed to remove these. They're fairly cheap--a good hardware store should be able to help. I'm a BIG fan of my neighborhood store, as opposed to Osh, HD, etc. Find one you can trust, and that has good advice, and you'll save lots of time, and sooner or later lots of $!
If you have another type faucet you should say what you have so someone else can help.
