I purchased one for my wife's bathroom. After trying it I purchased another for mine. Our expectations were greatly exceeded. So easy to use! We did not buy this to use less toilet paper but that has proved to be the case. We have a new saying, "I bid thee bidet (good day)"!  Kohler quality is evident. I did have a plumber install a temperature mixing valve so the supply water temperature is regulated for our comfort. I installed the seat to each toilet, the plumber hooked up the water supply. If you are considering a Kohler bidet toilet seat make the purchase and be surprised!
