A rain head is likely your best option. Is the back wall an interior or exterior wall? If exterior and you live in a colder climate I hope they made sure that the water line will not freeze.

it's interior wall. What are you thoughts on if I did a handshower w/slide bar and moved the slide bar near the corner of the short wall?

thank you for the suggestion on the rain head.

That's also an option. Just a shame that you will have the hand shower outlet up high on the wall with another exposed feed over to the hand shower. Maybe the hand shower rail could be mount horizontally starting from the existing outlet at the same height. Would need to see pics of the existing to see if this would look ok. There are ones that connect directly to the wall supply outlet.

Will need to be vertical. If a hand shower rod is used and positioned over to the side, can they not access from the other side of the wall and relocate the outlet to suit the hand shower rod position. They would only need to replace one tile to cover up the existing hole.

If the connection from the wall to the shower head were a foot long instead of a 6" or 8" and the drop was 90 instead of 45 it would not be angled toward the door. If you can do this ( and any plumbing supply can order it) then the type of shower head will not matter as they will all be at a down angle instead of out. I like the rain shower but that's just personal preference.

the water line goes from drain directly up back wall where the rough in you see now is located. In order to relocate to side wall, a whole row of tiles would have to be installed- pretty sure..

Plenty of extension arms of various lengths available.

bertani74 - from the pic I can only see the location of the control valve. I assume there is another outlet above this for the intended shower head, the pic does not show this. Maybe a pic from a bit further back would be helpful.

The shower door would get wet anyway likely, the challenge is turning on the water before stepping in, which I do not think you can do without getting wet. Not that that really matters. I think it looks nice in the center, but I would not have been too happy about it.
The plumbers and designers need to weigh in as to all of your options, if there any others.

From the new pic I would suggest you leave it as is and see if you have any problems under actual use. As others have mentioned, in a smaller shower it is almost impossible to not have a situation where water is not hitting the door. Express your concern to the glass people, they can make sure that the door gapping is as tight as permissible. There is also a little clear bubble type bead that can be applied to the glass edges to provide an improved seal.
