I have a problem with my masterbath shower head. Hot water (nearly
scalding) comes out of every other faucet/shower head in my house,
however my masterbath shower head only produces lukewarm water. There
are two other faucets in that bathroom, and they work correctly. When
we bought the house about 7 months ago, this was not a problem. It
has only been within the last month that we have noticed this. The
house is 2.5 years old, so I am confused and I am afraid of overpaying
a plumber to tell me that I am stupid and could have repaired the
problem myself. Please help! Thanks,

It is just doing what it is designed to do, maybe too well, maybe not.

Modern showers have valves designed not to allow the water to get too
hot. It sounds like your regular supply is too hot. I suggest that you
should reduce that temperature. I have heard of some valves that will over
compensate for water that is very hot. That might be the case and if so,
turning down the heat at the heater might make the shower warmer. The other
possible issue and one I have personally seen is the valve may be a problem
and it may need to be replaced (can any of them be adjusted?)
