So earlier you said:
Where I live some people complain about the leisure centre having mixed sex changing but I don’t see the issue because everyone has a lockable cubicle with high walls and walls and door going to the floor.
I am not an expert on changing rooms. However there are crossovers with toilet cubicles. When I have chatted to toilet manufacturers and cleaners, a big thing is maintenance. Toilets literally get everything thrown at them, and they can need a thorough clean of urine, faeces, vomit, blood and semen. If you use a mop with lots of chlorine to disinfect, it starts rotting panels that go down to the floor and it’s difficult to get rid of detritus that builds up along the edges and behind the door as you have to get into the toilet and shut the door behind you. In a leisure centre I have never come across cubicle partitions that are touching the floor of a swimming pool because of chlorine rotting the base and the water expanding the door so it sticks. The humidity in them must be bad. Another poster and yourself were talking about proper walls between each cubicle which I can imagine wouldn’t be so much of a rotting problem. The cost of doing this is much more substantial.
It’s good to be talking about design but there’s been many experts that have been doing this for decades and there’s rules and regulations to follow if you want to be compliant with building control - which I know a lot about regarding toilets.
You also talked about safe unisex spaces and said:
However, I think it is possible to build and manage safe unisex spaces. The economic reality is that unisex spaces usually cost a lot less to create and run. It’a both a question of what level of risk we are prepared to accept and also what level of cost.
You said that with such certainty about unisex spaces, as if it were fact. I know that the economic reality is that unisex toilets cost a lot more to create and run per toilet unit. For instance you need mechanical ventilation, a separate VAD device in each toilet room, a dryer and washbasin for each facility so the plumbing and electrics are more expensive to connect. You need 25% more units in total to achieve the same turnover because of the time spent washing hands (though men are scientifically proven not to wash their hands as often) inside the compartment. The positioning on unisex toilets is paramount too as universal toilets, with outward or inward opening doors, must open onto a well-lit corridor or circulation space. You can’t retrofit them into a single sex toilet block, behind a door. The layout when entering, exiting and using a toilet room or cubicle should cater for the safety, privacy and dignity of users. Toilet cubicle doors should only open into single-sex toilet accommodation.
I know that risks to anyone at their most vulnerable are much greater. In toilets, the most vulnerable groups are anyone having a medical emergency, women and children. As well as the extra cost, those are the demographics that you have to be prepared to risk by making everything private. Even in the case of an emergency evacuation from a building, ensuring everyone is out is harder.
There was an article about the joys of ‘gender neutral’ toilets by Adrian Chiles. Alastair Campbell also likes them. Men who like a long sit down in private like them. They can’t or won’t see the dangers.
