An inward opening door should swing in the direction needed to provide adequate passage.
Bathroom door open outwards.
I think your bathroom is also surprisingly similar in that you open the door and see the toilet the sink in the middle and the quadrant corner shower.
An easy low to no cost fix to this problem is to reverse the way the door swings.
Bathrooms lacking space are compromised by a door that swings inward.
This gives a somewhat unrestricted view of the inside of the restroom from the hallway which is not preferable to most people.
Unless the door opens directly into a set of stairs doors can generally be installed to open in either direction.
Make a bathroom door swing outward for more space.
Reversing the hinges and turning the door around places its hardware on the opposite side of the doorjamb or inner sides of the door opening.
The intent is to ensure that.
I appreciate your advice about the quadrant versus cubicle for space.
Current guidelines for bathrooms published in 2010 allow the bathroom door to swing inward as long as there is a clear floor space beyond the door swing when open.
If it bumps or blocks passage because of a wall barrier or other object when you open it such as a toilet or cabinet the door should swing in the opposite direction.
