Our old house when I was living with my family used to have one but we never used it.
So I have never used one in my life to this day.
It seems kind of useless because (a) I am guessing you would still have to set the correct temperature which is a waste of time and (b) I will still need to use toilet paper or a towel.
So I might as well go on doing what I do now which is to use baby wet wipes.
