Is there a performance difference between the round front and elongated front toilets?
Although manufacturers push the idea that there is not a difference in performance between round front and elongated toilets, the most recent round of MaP Test would indicate otherwise. In 2004 testing, the round front TOTO Ultimate MS853113 flushed 400 grams of test meso paste while the elongated front TOTO Ultimate MS854114 flushed only 325 grams. All things being equal, it would clearly indicate that in this instance the round front version performed decidedly better than the elongated version. Although it is a stretch to apply this example across all circumstances, this would lead weight to the idea that there is a difference in the finished shape. Although it would help to clear the issue, comprehensive testing of all versions of all models has not been conducted.
