Had two Therm-Oz showers installed in my house. I have four kids and am constantly struggling for the hot and cold balance for the past 10 years! I had these installed nearly a month ago and I absolutely love them. We can have the washing machine going, the kids can get in the other shower, or me and the wife can shower at the same time and we’re not struggling with burning or freezing. I highly recommend them and wish I had done them 10 years ago when I built the house. Don’t know how I’ve lived without them! Thanks guys.
