Showers use a lot less water. But, to fill the tub, it sounds like you'll
have to turn the water heater to a hotter temp. I finally ended up turning
my my WH temp, and now I can take a sit down bath.

That's probably true. I live alone, but found out with a medium sized
tank, I couldn't take a bath in a small bathtub without running out of
hot water. Admittedly, the wh was set to be fairly cold (100% hot
water would not burn my hand) ,and it would be enough to fill the tub
the first time, but the tub would get cold, I would drain water, and
put in some more hot, only to find out it wasn't hot at all.
I can give the OP details if he emails me. Remove nonono.
