I have a bathroom with a floor mounted water supply like in this thread:

The measurements are 3" from the wall and 6" from the toilet center line.

Toto's spec sheet suggests 8" from the center line, but another thread in this forum says that 3" should be okay. Is 3" okay for a floor mounted supply too?

If not, would someone suggest another skirted design toilet that would fit?

Thank you.
