Toto Toilet Fitment Guide

Note: Some styles of toilets may not allow the Washlet C100/A100 to be installed due to certain contours
near the tank and bowl area (see figures below). In the figure on the left side below, dimension D does not
allow enough open space to accommodate the minimum width of 11 inches.
