The Niagara Stealth Toilet is a toilet manufactured by Niagara Conservation that is designed to minimize water and energy use. The manufacturer defines the Stealth Toilet as an ultra high-efficiency toilet, as it uses only 0.8 gallon of water per flush.
Niagara Conservation claims that the Stealth Toilet uses 37 percent less water than a standard toilet. The toilet's low water usage is also designed to minimize the noise from flushing by using a vacuum system. The company offers additional products in its Stealth line that are geared for high efficiency, including a showerhead, a bathroom aerator and a kitchen aerator.
