great toto


This is our second Toto toilet (the previous one having a 1.6 gallon flush), and we really love the new 1.28 gallon flush on the Promenade. Everything goes down in one swoosh, the flush is not loud, and it works!! We considered the SanaGloss finish, but decided not to get it to save some money. So far, it seems fine without it!


no cons...

Other Thoughts:

buy a Toto! highly recommended
