Using disabled toilet with IBS

[ToiletUser]

Hi all. I have a feeling I may get flamed for this, but wanted some opinions as I honestly don't know if I am being unreasonable. Have NC as this post contains some embarrassing information!

I have irritable bowel syndrome, which I realise is a fairly common complaint and by no means a disability, but which does mean I often need to use toilets which have a sink in the cubicle. In my building, this means using the disabled toilet.

The other day, said disabled toilet was flooded and subsequently unavailable for several days, during which time I had (tmi warning) a rather explosive bout of IBS and could only use the normal cubicle toilets. It was humiliating and horrible. I had to keep exiting the cubicle to wet pieces of loo paper and I felt disgusting.

Shortly afterwards, the office manager sent round an email to everybody saying that, under no circumstances are able-bodied people allowed to use the disabled toilet.

So I guess my AIBU is: 1) are disabled toilets ONLY for disabled people, or are they just accessible for disabled people but everyone can use them? and 2) am I being unreasonable using them for the above reasons?

TIA

Sorry, in a rush so haven't RTFT but just wanted to quickly say to the OP that IBS is classed as a disability in employment law - DH is union rep at his work and has been involved with cases involving colleagues who suffer from it. Therefore you have every right to use the disabled toilet at work, and if your boss says otherwise he's a) wrong and b) being discriminatory.

Are you in a union? Might be worth raising this with your rep if you are.

It's awful how few places have the proper, changing places toilets. We went to eureka museum last year and I noticed they have one AND they let anyone in to use them who needs it not just visitors to the museum.

Sirzy my pet hate is Costas and their receipt with a code system - and awful, filthy toilets. Their cashiers don't even always hand you it ... so you have to ask (ie announce to all "EITHER ME OR MY KID NEEDS A CRAP").
I could understand if there were a steady stream of time wasters but every branch does it.
