Designed to fit most round-front toilets, this KOHLER® Cachet toilet seat combines subtle styling with innovative technology. This round-front 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.
