I'm installing a new acrylic shower pan and the drain pipe is off an inch from where the new pan needs it to be. I don't have a ton of room to make adjustments here. I want to use a mechanical seal drain instead of a solvent weld drain so that there's not as much stress for this DIYer to set the pan perfectly on the first try. So that rules out an offset drain. Are there any fittings I could use to create the inch offset I need here?

I thought about two 22.5 degree elbows, but that takes up too much height. My only other thought would be to replace the trap to adjust the angle, but off to the right (in the pic) are a lot of other fittings that all tie into the main, and it seems like that would be a way more complicated route.

The drain pipe is 2".

    If you can cut it in a place where it can be acceptably coupled, replacing the trap is not particularly difficult and completely solves the problem. You should also include the size of your drain line as it's not obvious from the picture. – K H May 6 at 6:50

    Is that a pair of stacked 2x4s acting as a floor joist, then cut all the way through? Please tell me it's not! Also, which way does the drain need to move? – FreeMan May 6 at 12:25
  • @KH I've added a second pic to show more of the drain pipe. The drain is 2". – ARich May 6 at 13:53
  • @FreeMan the drain needs to move towards the top of the pic, so deeper into the cut in the joist. – ARich May 6 at 13:55
  • Unfortunately I'd probably be cutting out that entire assembly and reworking it. There's no good place to splice. That's not too bad a project, though. – isherwood May 6 at 13:56

I could find no fittings to do what I needed to. I ended up cutting the entire assembly off at the main and rebuilding it from scratch to gain the inch I needed.
