Many businesses proudly display the familiar wheelchair symbol on the door of their accessible toilet.
But when did you last actually go inside and look at the facilities from the point of view of somebody who needs to use them?
Providing an accessible toilet isn't simply a matter of fitting a wider door and a couple of grab rails.
Poorly positioned equipment can turn what is supposed to be an accessible facility into an obstacle course.
Can people actually reach everything?
One surprisingly common problem is the hand dryer or paper towels are mounted far too high. It might be perfectly convenient for an able-bodied person standing at the basin, but what about somebody using a wheelchair?
The same applies to the soap dispensers, mirrors, toilet paper and emergency cords.
Then there's the washbasin itself. Can a wheelchair user comfortably get close enough to use it? Is there sufficient space underneath? Are the taps easy to operate for someone with limited dexterity?
A beautifully fitted washbasin isn't much use if the person it was supposedly designed for cannot reach it.
Don't use it as a storeroom
Another complaint frequently made about accessible toilets is that they gradually become unofficial storage cupboards.
Cleaning equipment, spare chairs, boxes, highchairs and stock can creep into the room because there appears to be plenty of unused floor space.
Except that space isn't unused.
It is there to give wheelchair and mobility-aid users sufficient room to manoeuvre and transfer safely.
That red emergency cord matters
Emergency pull cords are another area worth checking.
They should be readily accessible to somebody who has fallen to the floor. Yet cords can sometimes be tied up, shortened or tucked away because somebody thinks they look untidy.
An emergency cord that cannot be reached in an emergency isn't doing its job.
Try looking at the room differently
Business owners and managers could carry out a simple accessibility audit.
Either ask a disabled friend to check it out, or sit in a chair and look around the room. Can you reach the soap, taps, dryer and toilet paper without standing up? Is the mirror usable? Could you get alongside the toilet? Could you reach the emergency alarm from floor level?
Better still, ask disabled customers and staff what works and what doesn't. Lived experience can identify problems that somebody following a checklist may never notice.
Accessibility also extends beyond the toilet itself. Is the route to it genuinely accessible? Is the doorway obstructed? Is it kept unlocked and available, rather than requiring customers to embark upon a hunt for the member of staff holding the key?
Accessibility is about people
Businesses can spend considerable amounts of money installing accessible facilities, only to undermine that investment with something as simple as putting the hand dryer six inches too high.
Good accessibility shouldn't be regarded as an inconvenience or a box-ticking exercise. It means considering how real people with different levels of mobility, strength, reach and dexterity will actually use your premises.
So here's a worthwhile challenge for every café, pub, restaurant, shop, office, hotel and visitor attraction:
Go and inspect your disabled toilet today.
Not while standing up and assuming everything looks fine.
Look at it from the position of the people it is actually intended to serve.
You might be surprised by what you discover.
That's Business believes good accessibility is good customer service, and often relatively small changes can make an enormous difference.
Why did I write this post? I visited a restaurant, checked the disabled facilities and thought: "No! This just will not do!"
