Is 50 gallons of fresh water enough for boondocking?

Topic- Showers. Apparently many people use most of their water for showers. We are seniors and grew up when people commonly took about 1 full bath or shower per week due to many reasons. Today younger people freak out over this and to us seem to be obsessive-compulsive over cleanliness. A long shower daily versus one every 2 to 4 days makes a lot of difference in water consumption. Yet this is sufficient with some variation with humidity and activity level.
.Health professionals will tell you that there is no health reason to bathe daily and it may even be harmful. Odor varies but seldom occurs when not bathing daily. Just a FYI.
