Why does the temperature gauge on my shower have so little margin for error?

629 views

All my life. Every shower I have ever been in has the most sensitive temperature gauge. One tiny movement turns the water from freezing to boiling. Doesn’t this kind of defeat the point of having a whole swinging arm when I can move it a millimeter and feel like I’m burning myself?

There is a thing called a pressure balancing unit that sits behind that valve that can help adjust for the difference in water pressure between hot and cold. My shower at home did exactly this, either freezing or boiling, until I changed this part. Cost about 20 bucks
