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.
Step 1 - Start With Baking Soda, Vinegar, and Hot Water. Place about two cups of cold water in a deep pot on the stove and let it come to a boil. In the meantime, unscrew the bathtub drain cover, or simply unscrew the stopper if that is the type you have, and pour one cup of dry baking soda down the drain, waiting about one minute.
