My guest bath tub is not getting hot water. We don't use it that often
but the last time we used it had hot water. The sink in the same
bathroom gets ho****er only the shower doesn't.
I read on the google and someone suggested cleaning the "filter under
the faucet". Where is it located?

We are expecting family for holidays. We need to get it done asap.
Thanks for all your help.

No filter on the tub. Disregard.

Post back with the type of faucet. Single Handle? Brand ?
How old?
