would you consider the bend on the drain pipe end, an S trap configuration or just your average p trap?
No S Trap..

Not an S trap…and not your average P trap.
But a P trap nonetheless.

The key is the trap arm - there should be one. I use twice the pipe diameter as a suitable length. In this case, the trap arm is there - barely.

It’s not pritty…but as long as you can see a water seal down the drain with your flashlight and the conTRAPtion is not leaking or emitting bad smell, then it is functional as a P trap.
Just an ugly leftover over whatever we have fitting to make a p-trap. LOL

Morning, Kent. Hope to find you well.
What constitutes a P-Trap as to what constitutes an S-Trap.
I would not consider this ‘somewhat unusual’ DWV plumbing arrangement an S-Trap. It is a P-Trap.
In my opinion; a P-trap does not have to be directly under the drain.
IN you image the sinks tailpiece and trap did not line up vertically. The plumber use 2, 45 degree DWV fixtures to align the tail peace with the U Trap.
I always listened for gurgling. Then smell for gas.
Will the “trap weir” the highest point of the water seal, prevent sewer gases from entering a building allowing waste water to flow out of the trap into the drainpipe with a sufficient amount of water is held above it to form a barrier against odors and gases?
Is the drain pipe entering the wall sloped properly to drain water?
Those are my thoughts.
So if the trap arm was too short, what kind of a trap would this be called?
If the trap arm is too short, the trap may function as a “Siphoning Trap” or, more specifically, it could be considered an “Unvented Trap” or “Running Trap”
“S” trap, of course.
