KOHLER Transitions is designed to accommodate the needs of both adults and children without requiring separate toilet seats and combines subtle styling with innovative technology. This Transitions elongated standard toilet seat mounts easily from the top of the bowl using only a screwdriver, thus eliminating the need to reach under the bowl to tighten. And with other features like Grip-Tight bumpers that hold the seat firmly in place to prevent shifting, Quiet-Close technology to prevent the seat from slamming, and a ReadyLatch hinge to make seat removal easy for cleaning, we give you the right mix of functionality and style to bring comfort to your daily routines.
