Oh I can retire!! Hurrah! Thank you. I will sleep tight tonight 😍
The bit I would add to this which are more difficult to access is the building standards bs6465 part 1 from 1984 which were the standards in place when the 1992 legislation was being drafted up. There are some crucial paragraphs about door gaps (my specialist subject!) and cubicles and rooms below.
The standards show clearly that a cubicle is not a room. It’s a bit like saying a wardrobe in a bedroom is a separate room.
This means when the 1992 legislation says that the only mixed sex toilet is one that is in a separate room, it does not mean a cubicle.
Here’s a couple of paragraphs from bs6465-1 (1984): ...where a range of WCs is provided, each in a separate cubicle within a single room, e.g. in schools, offices, factories, public buildings and public conveniences, it simplifies ventilation, cleaning and, to some extent, supervision and prevention of wilful misuse, if the cubicle walls terminate above the floor as well as below the ceiling. These advantages are gained only at the expense of a certain degree of privacy. Where cubicles are used, the whole room in which they are situated may be regarded as a single unit for the purposes of ventilation.
Where partition walls and doors of WC cubicles are kept clear of the floor, the clearance should be not less than 100 mm and not more than 150 mm. Partitions and doors that terminate below ceiling level should be not less than 2 m in height from the floor.’
