So what is for me the "perfect" disabled toilet?
1. A button to press to "open sesame" the toilet door.
2. The toilet can be easily locked.
3. The toilet is clean.
4. There is a table, bench, somewhere!! to put your handbag, briefcase etc. other than on the floor.
5. There is a wall rail which is horizantal then curves up at either 45 or 90 degrees.
6. There is a drop down rail on the non-wall side of the toilet.
7. The toilet paper holder is not obstructing you when you stand to pull up your pants.
8. The sink, liquid soap dispenser and paper towels or hand dryer are close together.
9. The mirror is low enough for you to check your appearance and make appropriate adjustments.
10.A button will "open sesame" the toilet door to allow you to exit.
If I've missed something, I'll come back and amend it.
Just remembered -
11. Not sharing with baby changing.
