If that seems to far out, how about just covering the tub up to make it practical when not in use. The most practical idea is to cover it up and turn it into a bench . http://www.apartmenttherapy.com/ny/tubs-toilets-showers-sinks/relax-lounger-for-conoduo-bath-tubs-080057
Looking Back to Look Forward
The Article that first got my attention about bathroom technology was the April edition of Popular Science 2004. They list a few concepts that make mine look practical, but there is one concept in that article that I would really love to see, radio frequency tag readers. I would love to see these things though out the house. Radio frequency tags can identify an item kind of like bar code, but with out the scanning. Popular Science believes that if radio tags, RFID's for short, are added to medicine, your computer could tell you which meds you have taken and when. I think that would be great, but why stop there. Put RFIDs on everything. When you through away that empty bottle of shampoo, your home network could add it to your shopping list, or even better order it for you. In the bathroom this could come in very handy because there are so many different products that you only use occasionally, such as medicines or first aid items. Your home network could tell you when a product is going out of date or has been used up. Now that is a bathroom I would like to have.
