We've had taps and waste in the middle, shower at one end for about 10 years with no issues.
One thing to watch out for is a dual ended bath has two head ends and no foot end. So the slope is shallower making the showeree stand further into the bath and possibly the bath will be more sloping underfoot. Probably unnoticeable (ours is fine) but in our last place the shower was at the head end of a single-ended bath which had a more pronounced slope, and with soapy feet I'd sometimes start sliding towards the plug. Very comic.
OH GOD, conflicting reports... did you have issues with drainage?
