Can anyone tell me where the valve is? I keep running out of hot water in the bath, but have it everywhere in the house, so must be due to a valve somewhere?

Hot and cold water mixes inside the faucet (Valve), Please tell us the brand and the model number of you Tub/Shower faucet, and we will tell how to fix your problem, Thanks.

Not so fast, Fancy4650... First, tell us how big is your water heater, what temperature is it set at, how far it is from that bathroom, if you live in cold climate and whether is your house on slab or raised foundation. Also, answer Afaroo's question.

Based on this info, we will be able to give you more precise answer to your problem... Thanks... Milo
