I really want you to add this!

Discovery of the Century: A '1-centimeter breakwater' for urinal shelves!
Gentlemen of the world, how long must we continue to relieve ourselves while fearing the 'terror of sliding belongings' and the 'lost umbrella placement'?
I would like to propose a solution of the century that (might) send shockwaves through the construction industry.
1. The '1cm ledge' that saves a man's pride and his devices
We should install a small 1-centimeter square, or perhaps a beautiful right-angled triangular ledge (commonly known as a 'safety ridge') at the front of the shelf.
With just this, placed items will follow the laws of physics and gently nestle against the wall.
A fixed spot for umbrellas: Liberation from that futile struggle of 'it won't stay still, and it keeps sliding off'.
2. A challenge to the architects
'It's easier to clean if it's flat'? Can you really build the future with such a defensive mindset!
With just this one ledge, we can 'fully concentrate' with peace of mind. This is true barrier-free, or rather, a 'stress-free toilet'.
3. Could it be that a 'holy land' already exists?
If anyone knows of a pioneering example where 'actually, the toilets in our building have a ledge,' please let me know. That place is no longer just a toilet. It is a sanctuary where the 'pinnacle of consideration' has been realized.
