Is this shower screen length plus panel ok?

[FrCa]

Hi,

I have a 1200 by 800 tray in a recess with the 1200 the back wall of the recess, 800 on each side wall and then the 1200 opening across the front. Rain shower head plus handheld on rail on the 800 side wall where the screen will be fixed (ie furthest away from the opening).

Would a 700 screen with a 300 swivel return panel be sufficient to stop splash given this would allow me to make the 700 into a 1000 screen once in shower or angle it as necessary with the swivel; whilst still having a 500 opening as entrance into tray with the swivel panel turned inwards? Anyone got similar set up? I’d prefer the open feeling of a screen to having a sliding or bifold door as long as splashing won’t be an issue.
Thanks
