The pressure in the master bath decreases when I turn the hot water on.

Was it always like that or did it just happen ?

I moved into the house in Feb. about 2-3 months later it happened. I have not been able to use the master bath since a little before August.

It could be several things...

First, If this happens only in shower, than it may be clogged shower head or your pressure balancing faucet is malfunctioning.

Do you have single handle shower faucet ?

It happens not only with the shower, but faucet as well. My other bathroom works just fine.

Also, I have a single shower handle.

... and cold water flow on the same faucet is fine ?

I moved in Feb. 2008 and it happened around July 2008.

Now, if you open faucet: are you saying that cold water has full pressure and hot water side has little pressure ?
