Improving Bathrooms

Korean and Chinese and other bathrooms are really neat because they use a much more open architecture and contribute to a more designable experience for the user. I think there are a few important parts to this flexibility that make it really fun:

1. Water Room - everything is designed to get wet. It is easier and more fun. I think it could be a good design principal.
2. Feature full Floor - many bathrooms have wash racks mounted into the floor for people to do laundry. I think this could be extended to a few other features.
3. Continuous Experience - this is a bit less certain but it just seems that when I use bathrooms in Korea or China, whatever I am doing it feels that the tools are really built into the environment. I am not sure what I mean but I think it is a good feeling and I think it is something that could add to the experience of western bathrooms. Perhaps it is the really modular multi function nature of every aspect of this kind of bathroom. Each fixture seems to have distinct uses but also ends up emerging as a solution to many problems, just by the nature of the simple and elegant environment. 
4. Isolation from Dirt and enforcing Cleanliness - In these settings it is common for people to use small towels which is really nice for various reasons, and also use slip on shoes when they are in the bathroom. This is interesting because it combines to make a really fresh cleaning experience every time. That is to say; I think I feel a lot more clean after showering like this because you can concentrate on cleaning and you are sort of forced into cleaning. A small towel also works better to retain quality in your skin. 

That is all I can think of at the moment. I am trying to put together some ideas to make a bathroom design that ties a few ideas on washing together to create something that is a bit more efficient and a better experience.

Comments or stories about interesting washing experiences would be great. Especially if you know a lot about Japanese washing.
