We recently remodeled our home and I was excited to introduce a heated toilet set/bidet to the master bathroom. As part of our remodel we installed Toto in-wall tanks for toto wall mounted toilets which look beautiful. I found a great bidet seat by American Standard (made by Inax) and it seems that the parts needed to connect this seat to an in-wall tank do not exist anywhere.

We need to find an after market adapter to connect the bidet to the in-wall tank toilet that is long enough to get out of the drywall from the tank to the host connection.

Model numbers of each are below. Anyone have any ideas?
