My wife has a problem with our shower. She runs out of hot water before she is done with her shower, but there is still hot water at the bathroom sink. Can you help me?

With a thermometer, check the temperature coming out of the tub spout vs. bathroom faucet. Water coming out of the shower can feel cooler. The Tub/Shower diverter has an adjustment screw/slot, to allow raising the temperature of the water coming out of the Tub/Shower.
