I also take out the shampoo, soap, conditioner, etc. from the shower when done. Having it all clear makes it easy to keep clean and, best of all, seeing it all tidy gives me the feeling that I'm in some fancy resort or hotel.
Knowing that I'm lazy, and trying to use that fact to my advantage, I realised that if I have only one cake of soap for both hand-basin and shower, then I am forced to remove it back to the hand-basin when finished bathing. And so everything else such as shampoo just gets brought back at the same time.
It also means that there is only one thingy on which the soap rests when not in use. What does one call these - a soap-rest? Anyway, it tends to accumulate disgusting soap-scum remnants. And having the soap and the soap-rest thingy with me in the shower means that I can wash the horrible soap scum off it with minimal effort, and regularly, while bathing.
(I know that lots of people like liquid soap, and that this is not an issue in that case.)
Incidentally, I also put one little section of the bathroom cupboard only for bathroom cleaning stuff. Not a huge amount, just dishwashing liquid (more on that below), the same kind of sponge that I use for dishes, and some rags to dry things up.
The idea was that if it is right at hand, and not with other cleaning supplies, it will be used more often. It's been several months now, and for me it works.
On the dishwashing liquid: about six months back we had to get our bathroom re-done completely, as all the tiles has become porous with age. So I took advantage of that to ask the bathroom people what was truly best for cleaning bathrooms. Their answer was, as much as possible, use one of those shower scraper thingies to get rid of excess water when done bathing. Then to use dishwashing liquid for all ceramic surfaces, and a dish sponge for applying it. They pointed out that dishwashing liquid is designed to dissolve grease and dirt, which is exactly what you end up having stuck on the inside of your shower, bath and sink. And NOT to use anything that scratches on the surface, as it will gradually damage the surface, making it harder to clean.
I must admit I was pretty dubious - what about hard-water spots, mold, etc? But so far it has actually worked. Do still use toilet cleaner for the toilet though.
