The drain position has nothing to do with evacuation.

The drain can be wherever so long as the slope of the floor is done accordingly. If it is the low spot, the water will flow into it.

Maybe consider a linear drain?

How wide is that shower?

Is that a heating vent in the shower?

The position of the drain is irrelevant.

My drain is at one end of my shower because when I remodeled I took out the shower/tub and did a walk in shower instead so the drain is where the drain for the tub used to be. A shower drain is a different size than a tub drain so that had to be changed but the position is the same.

As others have posted, it is the slope that determines whether it will drain properly and my shower is well sloped so there are not even tiny pools of water or residual moisture anywhere.

FWIW I do have a type of hair catcher under the drain cover and the drain cover I got isn't screwed in so that it is easy to lift off and clean out all the crud that collects there. Having the hair catcher probably has save me a few plumber visits snaking out the line because the amount of crud that collects on my catcher is astounding especially since much of it isn't just tangled hair, If it didn't got "caught" up there it probably would wind up clogging the pipes.
