What Is a Stealth Toilet?

Known for being one of the most water-efficient brands in the world, Niagara released its first product called the Niagara Original Stealth toilet. This toilet comes with high-performance stealth technology that includes a whisper-quiet flush and a low-profile body with an elongated bowl.

These toilets offer the option between single and dual flush with the single flush using 0.8 GPF and the dual flush using 0.5/0.95 GPF. The Stealth toilet has no flapper and uses an air transfer system to discharge the waste contents by harnessing the energy of the water filling the tank and pressuring the bowl’s trapway.

We’ve picked out some of the best Niagara stealth toilets for you and listed their pros and cons. Read below to know more about these excellent low-flow toilets.
