: Toto has "Special Noter" for the Carlyle skirted toilet which says water supply rough-in is wider than standard 5 1/2" rough-in. Does this mean I will have to move my existing water supply line if I replace my old toilet with a Carlyle? My current toilet sits out from the wall about 3" now.

Richard,
The Toto skirted toilets work best with the supply located 8" to the left of center.
You can get by with 7".
Yes, it will need to be moved, The Carlyle will set about 3/4" from the wall.
