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.
Installation of bathroom sink plumbing proceeds in two phases. The first is the rough-in, when you install all the water, drain and vent pipes in the walls and leave them stubbing out at the sink location. In the second, or finishing, phase, you hook the sink and faucet to the stub-outs.The rough-in phase is the one that requires the most plumbing know-how.t's always easier to preinstall the faucet and drain onto a sink before installing the sink so you don't have to do these procedures while lying on your back. The pipe that extends down from the drain is called the tailpiece, and it should end at the same level as the top of the drain so that the trap connects easily.
