Overview
Installing the Kohler Cachet happens entirely from above the bowl with a screwdriver, so there is no reaching under the rim. The ReadyLatch hinge locks the seat in position and releases it for cleaning, while Quiet-Close hinges lower lid and seat gently.
Top-down installation and a hinge that releases for cleaning make this seat easy to live with in a busy bathroom. Grip-Tight bumpers resist the sideways shifting that loose seats develop. The listing gives no hinge spacing, so fit rests on the elongated label alone.
Who it's for
Replacing a worn seat on an elongated toilet without crawling under the bowl is the job here. Owners of round-front toilets should look elsewhere, as should anyone who wants features beyond a quiet close.
Pros and cons
- Installs from above with a screwdriver
- Quiet-Close stops lid and seat slamming
- ReadyLatch hinge releases for cleaning
- Grip-Tight bumpers resist side shifting
- Elongated bowls only
- Hinge spacing not listed
- Plastic build rather than wood
- White is the only color here
Performance notes
Fit depends on the bowl being a standard elongated outline, because the seat is shaped for that form. The Quiet-Close hinge dampens the drop so the lid and seat settle without a bang. Grip-Tight bumpers press against the rim to hold the seat in line, and the ReadyLatch hinge decides how easy cleaning is, since the whole seat lifts away for access.
