: I currently have a 1965 American Std 12" rough-in toilet and want to replace it with a Toto Carrollton. What should I expect in terms of additional time and expense (plumber charges) to change to the Toto instead of just replacing the existing toilet with a new American Std. toilet? This is a complete bathroom remodel. Thank you for your input

Donna,
I charge $10 more for the Carrolton installation.
However the last American Standard installation was not that easy really.
The Carrolton is a very nice toilet.
