I found this one on Amazon. I'm not sure I would want to shower with glowing lights though. As if I don't have enough to deal with in a shower - balance issues, tremors, etc. - add in a colored changing light and . . . . But, I think getting a hand held shower without a temperature sensor would work as well because I can sit on my shower chair/transfer bench and test the water on my legs before doing my shower.
