Thou shalt not hide the paper towel dispenser
I’ve been in lots of toilets where the paper towel dispenser has been hidden behind the mirror in between the sinks, but with no signage or other clue as to its location. And by the way, locating it between the sinks means that water will inevitably puddle on the counter, thus breaking the commandment relating to handbags. Architects also need to think about where to install hand dryers so that you don’t drip water halfway across the bathroom in search of the dryer.
Thou shalt design the layout to include a full-length mirror
How else can you check that you don’t have a strip of toilet paper hanging from the back of your outfit?
Thou shalt specify good ventilation to the toilets
Because if you don’t, they will smell. The property manager will then install a deodoriser that will simply overlay the smell of roses/strawberry/vanilla. So even if you’ve got everything else right, the toilets will be a failure.
I have no doubt some readers will find that I have overlooked a key design feature that should be added to this list, and I positively welcome your feedback which you can send through to email@example.com
