I bought another bidet kit this weekend, my old one I loved but it didn't last very long. Was not very heavy-duty construction.
This one seems a little more robust, and the price reflects it. Installs identically, with a plate containing a nozzle and control that goes between your toilet seat and the throne, and a water supply that goes between your existing hose and the tank. Less than five minutes to install.
And my goodness! The jet of ice cold on your boomer is bracing!!!
