I am trying to figure out why I run out of hot water for my bathtub.

Tub is from the mid 50's using a gas water heater.

I flushed out the hot water tank but it was only slightly rust
colored.

Thanks,

How old is the hot water tank? If I had to guess, faulty part inside
like the thermocouple or thermostat. I'd say if it's like 10 years
old or more, probably best to just replace the hot water heater itself
unless you are handy.
