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.
The top layer of water is what sticks to the porcelain. After every bath, youâre left with a thin film of dirt coating your entire tub. Fortunately, this film can easily be scraped into the drain using a bathroom squeegee. This prevents mildew, bacteria, and dirt from building up in your tub. You have poor drainage in your shower. Your shower is vulnerable to the same oily film buildup as your bathtub.
