It has always bugged me that those things require the installation of a second unsightly water connection for the anal rinse cycle. You would think that someone, somewhere has the engineering prowess to design a butt washing shitter that only requires one external connection.I installed a Toto Washlet today. Why? Free from parents (from an additional house in Wyoming that they no longer have by virtue of retiring and not working there any more) and because it's fabulously Japanese.
Hot butt + bidet function FTW.
Installation was pretty simple, with the only difficulty in getting the metal nut on the adapter piece cinched down without crossthreading on or twisting the plastic tube upon which the float floats. I had an extra 120V outlet put in by the toilet expressly for the purpose of powering this thing.
