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.

Don't have an answer. But my upstairs shower trap is tightly squeezed between the ceiling and floor. Just barely fits. Someone told me it's called a Los Angeles trap. ??????

If the diagram represents what you have now... I don't see an issue.

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 .
