We have a ten gallon water heater but seldom use it here in Mexico.
Typically we shower on deck with the solar shower when at anchor and
use the shore showers when in port. I especially don't wash my hair
down below because it's grown pretty long and mucks up the drain.

I have a 5 gallon but I think I must double the effort.
