Just to make it clear: the tub/shower is the only fixture that needs to have a p-trap buried under the slab (actually it is not usually buried under the is in a plastic enclosure in the slab under the tub/shower). The lav has its own p-trap that is connected to the waste pipe that comes through the slab. The toilet attached to the closet bend (an elbow). The toilet bowl has its own built-in trap. All of these fixtures, of course, must be vented to work properly.
