Excellent and extensive answers from both

LHR Director, reading your last I understood that the availability of extra large lavatories for people with disabilities is not common knowledge.
So I checked my own airline's website, and its info pages for disabled travelers.
Lots of useful information about the whole process, but
no mention of the special lavs that I know we have on 2 of the 3 aircraft types I work on.
I have fired off a mail informing our customer services department of this oversight. Thank you.
