The new Niagara Stealth Toilet is perhaps the greatest toilet ever created. This toilet uses only 0.8 gallons per flush, making it incredibly water-friendly. But what's best of all is that it has "the quietest flush on the planet."
Loud toilets always ruined late-night home re-entries for me as a high school student. Having a toilet that is not only great on water, but is also soundless seems like a no brainer. The Niagara Stealth Toilet is perfect for ninjas and shy guys/gals who have "work" to do but don't want everyone knowing about it.
