I've got this shower that I want to renovate, which includes slightly changing its size. Unfortunately this means relocating the drain. I have never re-done a drain before, and it seems the new location is somewhat tricky to get to so I was hoping I could get some advice on whether my plan is okay.The first picture in this gallery shows the existing setup and I am pointing to the location where I need the new drain (the "+" drawn on the piece of wood is the exact center). It's hard to see from that photo, but the downward facing 45 that is connected to the trap itself connects to another 45 that angles to the right and immediately goes through a hole in a joist right there (you can see the joist in the background just past my finger). This means I cannot easily cut back the pipe and put a new 45 degree bend further back because the joist is in the way and I really don't want to cut a larger hole in the joist. I just have enough meat left coming out of that first 45 (about 3/4") to connect something there.My idea is what I am trying to show in the second photo. That being to use a short straight piece (like 5-8", adding an appropriate amount of slope) after the 45 that is beside the joist to extend a little ways past where I need the drain to be and then curve the trap back around like how I am holding it in the picture. I hope this description is clear. The issue is that I am not sure whether curving the trap towards the downward facing 45 at such an acute angle is okay. Are there any other options I haven't thought of, perhaps? I will be using a shower kit system so the drain location will need to be quite precise. via /r/DIY http://bit.ly/2B35qns
