Key Features & Innovations




Electrolyzed water is a proven disinfectant used in food preparation and cleaning. Using the incoming water supply, a pre-mist wets the toilet bowl surface aiding in the elimination of waste approximately 80% better than a dry bowl. After each flush, TOTO’s eWater+ mists the bowl with electrolyzed water, reducing the need for harsh cleaning chemicals.
