I just bought a house and replaced the old hot water heater with a new 50 gallon Rheem hot water heater. This new heater is located in the laundry room adjacent to the kitchen. At the other end of the house is a 25 gallon point of use water heater for the master bath. The 50 gallon heater also serves the guest bath(I believe). The temperature is set at 125 degrees but the water gets cold after 10-15 minutes using the guest shower. The 25 gallon heater supplies hot water for 25+ minutes. (I have never run out of hot water in the master bath) what could be the problem? Is it a defective heater?

You may have a defective bottom element.

The elements should be tested to see if one of them is bad. If they test and pass, then you could have a defective thermostat. Contact the manufacturer to see about getting free replacement parts under warranty. It isn't uncommon for someone to put power to an electric heater before it is full of water and destroy the element(s).

Turning on the power too soon can NEVER damage the lower element, and if it damaged the upper one he would have no water. To find out the real cause, without wasting time guessing, we would have to be there and see the actual conditions. But, a 25 gallon heater would NEVER provide hot water for 25 minutes or more under normal usage.

What is the temperature of the water coming out of the water heater? At the guest bath? At the master bath?

It would if they are using it inline on the hot line and the main heater has one element out. It would be boosting the warm water from the tank to the point that it appears that the larger tank is working.
