How far below the shower drain does the P trap have to be?
I had to cut down the pipe that comes from the p trap and connects to the shower drain in order to create a floor pitch to the drain.
Looking down the pipe, the water from the trap is very visible as I only have a few inches of pipe extended from the trap.
This had me wondering if there was a min depth requirement that had to be met! Is there? If so, how far below the shower drain does the P trap have to be?
I'm guessing I am right around where the red line is.

There is no minimum. The minimum is sort of dictated by the size of the pipes and trap fittings. There is a maximum distance away from the drain laterally but nothing about it's elevation that I can recall.

Ok, I just measured and I have 3" of pipe before I hit the water from the trap. Maybe that's fine but I was not sure because usually you cant look directly down a drain as there is a stopper in the way of your view
