We recently purchased a Delta shower hand held wand for the twins’ bathtub with an LED temperature display. Trying to get the temperature right for them has always been a concern, too hot or too cold. We end up constantly checking the temperature while rinsing the girls.
We didn’t replace the entire fixture set in the tub, only the shower head wand. The LED display changes colors based on the temperature range so you quickly know if you are in a safe range. The best part is that it’s water-powered, so no batteries required!
Our only complaint is that the numbers read correctly when the water is facing you, but when I’m rinsing babies, it’s facing away, so I’m reading it backwards.
