Wellworth Dual-Flush Tank K-4458-7

The KOHLER Wellworth dual-flush toilet tank offers 1.1 or 1.6 gpf through a left-hand nested trip lever. Its side-mounted lever leaves the tank lid clear and coordinates with the other products in the Wellworth collection. Because the trip lever sits on the side of the tank like a traditional toilet, the top stays flat and open for the small items you want within easy reach. When you pair this tank with the compatible bowl, you complete a Wellworth or Highline toilet that brings dependable performance to your bathroom. Coordinating beautifully with other pieces in the Wellworth collection, this tank helps you build a space that feels considered, cohesive, and ready for everyday life.
