How can I address the reduced clearance behind the overflow and drain in my new bathtub to properly run the overflow down?

Hey, have you noticed that the new bathtub has less space behind the overflow and drain? What’s your plan for running the overflow down in this situation?
Is your new bathtub longer than the old one? Or did something at the other end cause it to shift?
Nope, just a standard 5′ tub. The main difference is that this tub stands alone, unlike the previous one which had a built-in surround, giving more space behind the overflow and wall.

In short, it’s longer… Haha.
I’m curious about the structure under the floor. That horizontal 2×4 doesn’t look like a typical floor joist… And what’s up with the angled board?
Is on the second level floor joist.
Can you provide a wider shot of the framing so I can better assess the situation? Thank you!
Hey, I think said it looks like this
Ot it, an anonymous participant mentioned that. Let me take a look…

It seems challenging to enclose those open web trusses. Have you attempted to see if the overflow pipe can be placed between the tub and the truss flange?
Unfortunately, a straight down approach and then a 90-degree turn won’t work for the drain.

When it comes to plumbing, there are various ways to customize – there isn’t a single correct method to drain this tub. Instead of worrying about what’s beneath the floor right now, is there enough space for the overflow drain (1¼”) to fit snugly between the tub, floor, and truss flange?
Yeah, there’s space for the pipe to go through, but it can’t come directly down from the overflow
