TOTO UltraMax MS854114S

  • Easy-to-clean, one-piece design
  • Reliable flush performance
  • Seat included
  • Expensive for a standard toilet
  • One-year warranty

The Toto UltraMax MS854114S is a good 1.6 gpf toilet. It has a one-piece design that's simple to install and eliminates the gap between the tank and bowl that's difficult to clean. Owners say the flush is quiet and the included seat closes slowly so there's no annoying clanking sound. This toilet has a one-year limited warranty and is available in four colors. If you're not stuck on a one-piece design, you can save quite a bit by going with a standard two-piece toilet. The Toto Drake CST744S (*Est. $255) has a slightly higher rating for waste removal in MaP testing, and is said to be particularly reliable.
