I installed one for my wife in the master bath, but it does not heat the water. It has an on and off button, a button for the front and one for the back and a self cleaning button. The knob adjusts the water pressure. It was cheap on Amazon, about $35-40, but she likes it. Recently, she received a fancy one from one of our kids that has a night light, heats the water, etc. Now, I will have to install a wall power outlet so I can plug it in. I'll have to install it in the guest bath, since that is the only place with power close enough that I can run the line to it. The cheap one works fine and she is happy with it. It is a simple DIY project. So easy, I didn't even need to use a youtube video for instruction...
