I think the OP meant, get rid of the toilet water expense. From what I can tell, the toilet is arranged so that gray water from the sink is used to fill the toilet tank. When you flush, it uses that once used sink water to rinse and fill the bowl. This isn't new. Just not something most people are willing to deal with. For one, the back of the toilet needs to be accessible and that isn't how baths are typically designed.
