Bathtub drain rough-in. The standard bathtub/shower combination will require an 1-1/2 drain and p-trap installed to your local plumbing code. The drain must be graded(sloped) at a minimum of 1/4 per foot and must be vented. This can be done in one of two ways, by wet venting the trap arm fixture drain or by individually venting the bathtub.
Soap scum, hair and other debris can easily block a bathtub drain, and the blockage tends to grow as the water flows more slowly and allows more sediment to settle. If you don't know where the blockage is, the tub drain is usually a good place to start looking for it, but not if sink water is backing up into the tub.
