The Soap Dispenser on Public Toilets

Every time I wash my hands in a public toilet I notice how badly positioned the soap dispenser and sink usually are. 

Yes, you should wash your hands with soap ... And, to do so, making use of the dispenser usually creates a big mess.

Soap dispensers regularly are placed to the left of the sink. If there are several sinks next to each other depending on where you are standing it might be to the right ;-)

The dispenser is mounted in a way that if some droplet of soap - given principles of gravity - drops, it drops on down to the floor.

Watch out for it! - You will rarely find a public toilet where underneath the soap dispenser there is not a big mess. Even the regular cleaning by cleaning staff over time can not cope with permanent stains.

The worst is with automatic dispensers. Dispensers having a sensor and dispensing only after the hand has been moved underneath. - Given the issue of latency time ... these designs are just too slow ... (see also my articles on general issues with latency in the automatized and digital world: Latency no. 1 and Latency no. 2) ... to securely drop the pre-specified amount of soap into the users hand. Usually one has already pulled back the hand before the soap dropping, resulting in systematic mess with soap on the floor.

As a result it then requires at least two attempts by the end user in order to get his soap into the hand which heavily impacts soap consumption.

A little bit better are dispensers which deliver soap as foam. The improvement here is just that the foam either sticks to the dispensers nozzle, or that the portion of foam does not drop that fast, so that a fast reacting user can still catch it before it is hitting the drop zone on the floor.

Now, the big question: why is this almost everywhere - exceptions apply - the case?

• Is there a norm or standard that requires such design?
• Is it just because nobody cares?
• Is it because consumers and users just accept it and do not complain?
• Is it because the cleaning staff just accepts it?
• Why?

I doubt that I am the only one to notice. And I doubt that I am the only one who sees this a problem.

And given the enormous number of public toilets around the globe I doubt that there is no opportunity for a decent solution to that problem!
