Thanks for looking that up. I think we're IPC, but when I had my rough plumbing inspection done, the inspector was much more about how bathrooms are conventionally done than about DFUs, etc. Regardless, my understanding is even if UPC allows a horizontal vent, wet venting it from the sink is still preferable since it will clear the drain, whereas a horizontal vent might get clogged.

The picture confuses me, though, since there must be a lot of depth below that shower to support the vertical sanitary tee. Mike, if you do the horizontal vent, you could vent the shower drain with a wye (on its back or tilted 45) to lower the vent quite a bit. If you can't get the vent lower in the wall (is there a footer there?) you could take it down with a 90 where it leaves the wall and build a shower bench there that covers the pipe.

Yes, there is a lot of height, the P trap is way up above the horizontal drain pipe.

So, it makes sense I think as you suggest to lower that end down with the vent going down with it.(probably 5 inches lowering)

But the vent cannot go below the slab as drain too shallow, so may just run on top and meet the (new)Y arm coming up.

Then at least the vent is as low as it can be
