Sculpted with flowing and balanced curves, the KOHLER Veil one-piece toilet has a bold minimalist style with a skirted trapway that is easy to keep clean. The dual-flush trip lever offers the choice of 0.8 or 1.28 gallons per flush. At the lower 0.8 flush setting, this dual-flush high-efficiency one-piece elongated toilet can save as much as 6,000 gallons of water annually over a traditional 1.6 gallon toilet.
