You can get them on Amazon for $100 Install is a lot more because they require a dedicated circuit (if you're doing it up to code) so you have to do a home run to the panel and open up the wall for a switch. So unless you're doing a bathroom renovation it's a lot of work. I did the wiring for my sisters house they were renovating and mentioned these and now they have them in both of their full baths. https://a.co/d/0bDmBpri
