With its concealed tank and minimal footprint, the innovative Veil wall-hung toilet saves up to 12 inches of precious bathroom space over KOHLER's longest floor-mount models. The mounting hardware is completely concealed, giving Veil a sleek, seamless look that is incredibly easy to clean. And with dual-flush technology, this high-efficiency toilet can save as much as 6,000 gallons of water annually over a traditional 1.6-gallon toilet.
