Re: Case toilets?
So it can't use standard plumbing components? My original toilets were long since removed, but I still have a 1949 toilet. The porcelain lasts forever. I have porcelain accents around some tub faucets and they are still perfectly bright white, while the ceramic subway tiles has yellowed slightly over 90 years.
Throw it out there on craigs list or some antique auction site. Some looking for authentic renovation might take it off your hands and maybe at least give you a few dollars.
In some areas water isn't that expensive nor is it in any kind of short supply so an extra 3 gallon a flush isn't a big deal. Actually, around here we have too much water on our river 90% of the time. Although even as cheap as it is, it still adds up if you put over a thousand gallons on your lawn twice a month.
