Just received an email from Christine. The NH toilet installation is in place of the standard flush toilet, but everything else in the black system remains - black tank, fresh and waste plumbing, dump valve, and shut-off valve. She said it is not practical to install a fresh water tank or storage underneath and it would be too hard and costly to install a regular toilet if the other parts were not there.
Cost of the Natures Head option is $800.
Sorry, but IMHO this is utter BS. If I wanted TWO complete waste systems I would be happy as can be, but this approach is bogus. If Oliver is going to offer the composting toilet, then they should engineer and offer a creative solution for 2.5 cubic feet of unused space under the bathroom floor.
I am bummed. How about you guys?
