Lol
i use a wheelchair mostly but do sometimes use a walker.
so, to go through typing it out again:
imagine I am going into the ladies with my walker.
i go into a cubicle. There’s the toilet, then my frame, then me.
there isn’t space to turn round properly so I need to shuffle round as if I am turning on the spot. Realistically at that point I need someone else holding me and or the frame to make sure I don’t fall.
when I’ve shuffled round enough (maybe 45 degrees) there’s enough space for me to sit down partially on the loo.
from there the frame can be shuffled round and then the carer can shuffle me sideways so I’m properly on the loo.
if the frame is in the loo cubicle the door can’t shut.
so either:
the carer takes the frame out and holds the door shut (I can’t reach the lock in most cubicles)
OR
I do my shit with the door open.
I have done both but honestly I prefer having the door shut.
once I am finished and I wipe myself either:
if the door was open I can with help from my carer stand up and use the frame to go straight out
or if I didn’t want to shit in front of everyone me and my carer reverse the operation we did to get in.
it is similar to doing a five point turn in a car only a lot worse.
if it’s just me and my frame I physically cannot move to sit on the toilet in a normal sized cubicle.
I genuinely don’t know how else to help you understand this. Some people physically cannot use the cubicles in a normal toilet due to their disabilities, that’s why they need a disabled toilet.
