Kohler k-35956-0 Claude Toilet Tank 1.28 Gpf

Product Description

The KOHLER k-35956-0 is a toilet tank designed for use with the Claude two-piece toilet, a skirted-trapway unit that combines architectural molding-inspired detailing with a clean, low-profile silhouette. This tank operates at 1.28 gallons per flush (GPF), meeting WaterSense efficiency standards common in residential plumbing installations. It is paired with the Revolution 360 flush system, which uses a swirling action to improve bowl coverage and reduce buildup. The exterior surface carries a CleanCoat treatment that resists mineral and waste deposits. Licensed plumbers and finish trim contractors handle this type of installation in new residential construction and bathroom remodel projects.

The Claude tank is sized and engineered for the Claude two-piece toilet configuration. The ReadyLock installation system secures the tank to the bowl without requiring drill holes in the finish surface, reducing installation time and simplifying alignment. The fully skirted trapway on the companion bowl gives the finished assembly a smooth, seamless exterior that is easier to clean than exposed-trapway designs. This tank is suited for residential bathrooms where both aesthetics and water efficiency are specified.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and flush the existing system to drain before removing or installing any tank components. Use the ReadyLock connection hardware as specified in the installation instructions to secure the tank-to-bowl joint. Do not overtighten tank bolts, as this can crack vitreous china.
