Limited Hot Water In Shower‏

Question: The shower in my bathroom never runs very hot, although I think that even after a tepid shower I can still get hot water from the sink. What's up with that? The hot water heater is right across the hall from the bath, what causes the cold showers?

Answer: Many of the single handle tub/shower faucets have a temperature control installed so that you won’t accidentally get scalded from hot water if someone flushes a toilet or runs the water elsewhere in the home.

Although they are called temperature controls, most operate on the basis of maintaining pressure, so if the cold water pressure drops at the faucet, the faucet compensates by allowing more cold water to enter the mixer portion of the body. They are adjustable, usually a screw in the center of the faucet assembly.
