Bring sleek symmetry to your bathroom with the KOHLER Persuade Curv toilet tank, a dual-flush design that pairs refined style with meaningful water savings. An innovative nested trip lever, mounted on the side just like a traditional toilet, lets you choose between a 1.0- or 1.6-gallon flush while leaving the top of the tank flat and free for storing small essentials. The left-hand nested trip lever puts effortless control at your fingertips, and the included supply line simplifies installation.
