My employer has just removed single sexed toilets to be more inclusive!

Trying to use provisions of the Equality Act to fix the problems with this particular workplace is like trying to hand out parking tickets to prevent arson.

Your employer needs to step up, step in, and take proper disciplinary action against anyone (most likely men, but anyone necessary) who fails to keep the facilities in a fit and proper state for other people to use. It really isn't anything about what the sign on the door says.

We have the same in one of our buildings and one brilliant woman put a big basket of sanitary protection in one of the three individual loos with a sign saying “Help yourself!” and now all the men go into the other two loos because they are scared of the big baskets of sanitary protection 🤣🤣🤣. So we have one nice clean loo with no pee on the seat/floor and the men all poo in the others which is fair because the workforce is 3/4 male.
No trans employees there though.

What kind of place do you work in?! Smearing faeces on the walls?

I’ve worked in offices where we had to share it with children and teen service users and not even experienced that!

We are moving to a new office and we have this issue. I have raised this too. Our office is 78% men and when I see emails about not smearing faeces on the wall I know I never want to share any facilities with them. They already use the disabled toilet as the poo toilet but it's causing a lot of stress thinking about having to share and also brush my teeth in a single cubicle that smells.

That's this Lewis Silkin who changed their advice but still identified as not being wrong?

Unfortunately OP I think it's a grey area. Might be worth asking why you previously had single sex at all? What was the justification for single sex provision previously, and what has changed since then?

If you do have to use, or avoid using, a toilet that is dirty, OP, complain loudly to your manager Also, email HR with your complaint and asking how the toilets will be kept clean during working hours. No-one can accuse you of being anything -phobic, you're complaining about hygiene and an acceptable working environment, or lack thereof.

Also, I do hope there are sanitary waste bins in all the toilets.

I have to share a toilet with patients and staff. It's vile. It's either smeared with shit from sick elderly patients or the men have pissed all over the floor and seat. This is a daily occurrence. Quite honestly despite my terf credentials I'd sooner share my toilet with a trans woman than have to hold my bladder day after day because of this disgusting situation. Maybe that's what they want.

We had these and the issues with cleanliness and hygiene were awful. Got so complaints were daily.

Fully enclosed lockable individual toilets are far less safe than single sex spaces with door gaps. Only providing those may amount to discrimination against people with disabilities that leave them vulnerable to a medical incident l, eg people with diabetes or epilepsy.

Additionally, they expose women to having to use toilets that have been made disgusting by men pissing everywhere but the toilet bowl.

Really uncool of your employer, OP. How incredibly lazy of them to throw women and those with medical conditions under the bus like that.

If they are enclosed fully then they are fulfilling their obligations.

That’s annoying but I think legal.

I used to work for an office that had the loveliest toilets lol all individual lockable with their own sinks and smelt nice but they still were labelled male and female which I appreciated.

That only relates to when more than one person is using the facility at the same time.

We have mixed sex toilets at at work and always have done. There is one toilet on each floor and they are fully enclosed with sink in the same way as a disbled toilet might be.

Are they fully enclosed with a sink and drying facilities inside the cubicles. If not I don't think that is legal

That is legal.

“The EHRC guidance that it “is compulsory to provide sufficient single-sex toilets” could be misconstrued.
Health and Safety regulations say that separate toilets for men and women are required “except where each toilet is in a separate room lockable from the inside”. A fully mixed-sex toilet provision is allowed under these regulations, provided they meet these conditions. If you have toilets which are not in separate lockable rooms, then the health and safety regulations say that you must have separate provision for men and women.
”

I don't think that's legal. Employers are obliged to provide single sex facilities under the Workplace (Health, Safety & Welfare) Regulations 1992. Take a look at the legal guidance below from solicitors Irwin Mitchell:

From the link below that (although aimed at retailers) covers employer's legal responsibilities:

"Mixed sex facilities may indirectly discriminate against those women who need single sex facilities for their privacy, dignity and autonomy. That might be for religious or cultural reasons or because they want privacy when they are menstruating. It may also be direct sex discrimination..."
