Rated 1.0 out of 5.0 by Save Yourself the Trouble and Do Not Purchase this Product! Purchased this today and installed in five minutes, then realized this K toilet seat is very poor quality. Purchased as a replacement seat for our K toilet. Although it is attractive, it is uncomfortable, slides around (it does not have any, ANY rubber or soft plastic bumpers, and when you close it, it is the loudest seat I have EVER heard. CHEAP CHEAP CHEAP!! Will be purchasing a replacement for our replacement tomorrow. It's true, you get what you pay for. January 25, 2015
Rated 1.0 out of 5.0 by New screw holes are smaller than standard Dear Kohler, If you're going to re-engineer a toilet seat so it has a quick-disconnect for cleaning, then can I suggest you either make the new screw holes the same size as all the standard ones, or else include the needed smaller ones? Because if I have to go back to the store to purchase said screws, there's about a 100% chance I will return your product and buy one made by someone else. November 22, 2014
Rated 3.0 out of 5.0 by Skip7 I bought and installed 2 seats in July 2012 because I liked the product but I soon found out it wasn't the quality I expected from Kohler The seat mounts were flimsy and would not stay tight. I was able to modify the mounts with different type hardware to make the product work. The hinge on one seat broke within the one year warranty and Kohler replaced it. When the second hinge broke, I ditched the seat and bought a Church seat. What a difference in quality, durability and mounting hardware. I will never by another Kohler toilet seat. May 21, 2015
Rated 3.0 out of 5.0 by sinking feeling Bought this plastic seat to replace a painted wood seat with inferior paint. Confident that the finish will stay shiny and new for a long time. However, the seat design gives me a sinking feeling. Perhaps, that was intentional to make the person ergonomically sit to accomplish #2. April 9, 2015
Rated 4.0 out of 5.0 by New Seat Once I got it installed, I was very pleased with it. Microscopic installation instructions and so had to figure it out on my own which took a while. After installation, I can appreciate the design but it would have been nice to have readable understandable instructions May 12, 2015
Rated 4.0 out of 5.0 by Good Value. Easy Install. Install was easy. The seat and hinges are fairly durable. Good product for the cost. April 8, 2015
Rated 4.0 out of 5.0 by It works. It is a toilet seat. It is elongated. It is white. It keeps you from falling into the bowl if you sit down. It has a lid that both opens AND closes. It is functional. Next time I need a white elongated toilet seat I will consider this again. February 10, 2015
Rated 1.0 out of 5.0 by Toilet Bowl Seat for Thrill-seekers If you enjoy the possibility of falling off your toilet, this toilet seat is for you. The attachment system is just really poorly designed. The seat too easily separates from the bowl. I'm not sure why Brevia strayed from a simple design that has worked for decades. August 12, 2013
