I put this on the other thread but thought I would also drop it here. There are practical considerations to sort because previous legislation and building regs based on health, safety and welfare did not consider that we’d get to a point where people were arguing it was their right to go into the toilet of the opposite sex.
If you have both sexes in a toilet cubicle or room, you have to change the design of every toilet to be a mixed sex design. That means scrapping Designs C and D in Document T, variations of which cover most of the toilet provision in the country.
The alternative is to change Health and Safety legislation and Building Regulation and ignore doing risk assessments and Equality Impact Assessments in the process.
When you get to the nitty gritty it’s no wonder there’s a delay.
