How can I regulate the temperature in the shower? We live in a townhouse. When we take a shower, the temperature changes from hot to cold. How can I fix this?

Replace your shower valve with one that has a Skald Guard or a Temp Control feature. Regards, Tom

There is a shower head that shuts down [closes] when the water is too hot. I do not remember who makes it.
