Dad using individual ladies loo to change baby – what’s the etiquette?

It's not discrimination if it meets both men's and women's needs equally well. Discrimination is about the impact of provision, it doesn't require that provision be exactly the same if the usage is different.

Making them both mixed sex would meet women's needs less well as more men would be using the single-occupancy cubicle, making it less accessible for women, and women would me unlikely to find the communal facility suitable to use.

Well
They are providing a single sex space for men but not for women. So yes that is discrimination.
In which case the only way round it is to make them both mixed sex

I was responding to whether it was sexist, not whether it meets building regs. And for that, while it wouldn't meet the current regs, I can't think of which it would have breached prior to last year.

Agree they aren’t.
You can have one mixed sex space

Well no technically from a building regs point of view it wouldnt conform as it’s not providing a separate space just for women but is for men.
Its a weird one
but it is a bit of a cock up tbh.

Not if it meets women's needs for the toilet as well as it meets men's.

This it utterly bonkers. Small cafes often only have one toilet. They aren't in breach of anything

Are you saying that you are old enough to have a baby and never noticed that the accessable toilet is normally also allocated as the ladies loo?

Try keep track of the wheelchair sign when you are out and see how many times it womens toilet and baby change too.

Do you believe that changing the social contract and making toilets mixed sex to benefit some men will also benefit all women?

Now that your husband is a dad how many mens toilets can he list where he can go that has a baby change?

Speaking to the manager raises awareness that baby changing is not womens work.

Is shows that you support the idea of having a baby change in the mens as it shows the service provider recognises the change in the social contract as men take on their share of child care.

And by your own discription that is a build design with a dedicated man space and no dedicated womans space.

So sexist by design

This is such a non issue. It was self contained units. I read the signage as "women and baby changing" meaning women can use this unit ALONG with anyone needing to change a baby regardless of gender. My husband has always used those facilities without batting an eyelid with our children. Different if it is inside a block of women's toilet where really there is an argument that fathers are not being catered for and it's more awkward for a man to come in. But a self contained unit? Honestly get a grip people. Maybe they can just improve on the signage and be done with it. What has the world come to though...

Actually I agree with you op that the staff probably wouldn’t take action if this was raised with them, they’d probably look at you like you were a bit dim and point towards ladies,

This.

It’s fine. It really annoys me when baby changing facilities are in women’s toilets. Changing a baby isn’t just women’s work.

He should ask the manager.
It would stress the sexist nature of the arrangement.
If there’s only one toilet for women and it has the baby change thats very unfare.
Women need the toilet more than men so there should be a unit in both toilets or somewhere else.

As an aside I don’t agree the toilets should be labelled as mixed sex or neutral.
Women need a toilet without wee on the floor and without the chance of a man hiding camera devices.
It happens more than you can imagine.

OP in the current circumstances of course your dh should use the facilities provided irrespective of location after he’s made them aware

I'd reluctantly accept this, but think that all sides (both women and men) should make the point to the café owners that men are parents too so also need facilities to change their babies' nappies.

The petrol station design does not move a man into a woman’s space. It uses a single occupancy room for a number of different uses for people of both sexes.

Its not a "safe space" it is a safer space as a semi-private space is without men. Separation of provision into either sex was in part about safe provision as men had the open urinal area
[(Edit) and women have to get half naked everytime they use a toilet ]

The term comes in part from trans ideology where some men need to have full access to womens toilets and spaces as these men need a safe space away from the violent men who use the mens room.

The safer space was designed into UK public toilets and still a factor in "third world" areas with no domestic plumbing. Having a clear social contract of no men ever allows the designers to create a man free buffer zone around the womens SSS eg access points to either sex will be designed as far away as possible rather than side by side.

A man hanging around the womens access point is a red flag for the police and community as a whole. The breach of the social contract begins as the man enters the public space buffer zone and before the man enters the toilet itself. Making the semi-private space a little safer.

But I agree removing men who spray urine onto the seat and lid of sanitary bin and the floor makes for a cleaner space.🤷‍♀️

Multiple people have called you out for being wrong - but I'm the arsehole? I'm frankly glad you're not engaging anymore. It's just a toilet. Really, it doesn't matter who uses it. That's all.

It's a single occupancy toilet not communial with stalls????? If I had to wait and saw a man coming out with a baby I wouldn't bat an eye.....

I'm hilarious? Okay!

Wheelchair access with transfer bars etc have been the law since the 70s but baby changing units are still not covered under any act.

There is a changing spaces campaign which helped change the building regs obliging big venues to design and provide specific disability equipment
https://www.gov.uk/government/news/changing-places-toilets-for-severely-disabled-people-to-be-compulsory-in-new-public-buildings

Yet even the bog standard Able unit is still designed for a man as the toilet is centered in the space with no obligation to design in a bin space or add even an extra few cms to the stall.

Haha you're hilarious. I concede that my previous post was incorrect and clumsily written.

I suspect I'm not the first person to say this to you, but I don't want to engage with you anymore. Have a nice evening and try to work on your desire to be unpleasant to strangers on the internet who don't share your opinion.

There is something fundamentally wrong with you when you're unable to communicate without resorting to insults. Maybe you have had a hard time in life (bullied, perhaps?), maybe you're just an arsehole. Who knows?

Since the OP has now said that the men's toilet isn't big enough for a changing table, I agree this would make more sense.
