AIBU to wish toilet cubicles were a decent size.

Toilet cubicle dimensions are governed by building regulations, some of which have evolved over the years. The solution would be to have doors opening outwards, as is the case already in some toilets.

I think at railway stations etc they should be bigger, it can be difficult to manoevre your suitcase plus your bag into them.
Agree about the doors opening outwards, it helps hugely.
They should all be like that at stations etc.

Sometimes the door would have to be open to accommodate my knees!!
Also they don't all have a hook for my bag.

Some public toilets are very cramped and it can't be hygienic to have to rub against the toilet bowl to get around the door - and that's when you're slim. It must be impossible for larger people. Having to squeeze past the bowl really annoys me.

As suggested, outward-opening doors would help a lot.

It also annoys me when there's nowhere to hang your handbag (who wants to put it on the floor?).

Don't mention the loos in an aeroplane although obviously space is at a premium on an aircraft.
I could barely fit in and I am averageish size.Many males are bigger than women just because they are men.
Those who can't, wait , I suppose.

There are a couple of places here where the only toilet is also the disabled one. They don’t have hooks for bags/coats in them. I asked staff if they could install hooks and was told they couldn’t do that because anyone in a wheelchair wouldn’t be able to reach up to a hook to use it.

I suggested they could put hooks in lower down the wall/door so most people could reach it and they looked at me as if I’d grown two heads! Honestly.

Mostly, it’s getting into cubicles with small grandchildren that challenges me. Thankfully, nowadays all but one can mange the loo on their own.
