How necessary is sanagloss for the Toto toilet?
I'm looking at a 1.6 gal Toto Drake. The model with the ADA height and elongated bowl does not come with sanagloss. The shorter height model does have sanagloss but I want the ADA height. Is 1.6 gal flush good enough so that sanagloss is not needed? OR should I go with the Drake II which is 1.28 gal with sanagloss? Salesperson said that she likes her 1.6 gal flush better than the 1.28. Which is better...Drake 1.6 without sanagloss or Drake II with 1.28 gal and sanagloss???
