The world’s first and only Ultra-High-Efficiency Toilet is here. The Niagara Stealth uses only 0.8 gallons per flush – half of what federal regulations require – thanks to our patented hydraulic technology. Innovative and stylish, the Stealth has a whisper quiet flush and low profile body. A round bowl provides comfortable seating in the even the smallest spaces, while a durable side flush handle adds a classic element to what is otherwise a very forward thinking toilet. And because of Stealth’s integrated flapperless technology, it’s virtually maintenance free. Think of it as the secret weapon of the water revolution.
