The concept of this bathroom is more about water conservation than anything else. Allowing a viewing screen you can actually see how much water your heating up for a shower and thus you can see how much your wasting on electric and water, reducing one will naturally reduce the other. At the same time it struck an idea with me as well for people recycling grey water and/or rain water as it makes just as much sense to go with tanks to show how much water is available and being used every time you use it. Its a stylish modern bathroom and I could see it being utilized in a shipping container home or at least its concept could be. Its definetely something that would make people more aware of how much they are using and in a stylish modern way.
Now the other key feature of this bathroom though is that it conserves water by utilizing the tap water to fill the cistern on the toilet which is another green feature that makes common sense on the shipping container homes just as much as someone’s lush penthouse.
