Do baths or 4 min showers take up more water? I would have thought in this day and age of water awareness baths would be slowly dying out?
There a lot of reasons why a bath can be needed.
If you've got kids. And if they play sport. And if anyone has injuries.
I have leg and back problems. I need to have a bath once a week or so. And when my legs were at their worst I was recommended to soak them more regularly.
A few years ago I had two broken elbows and I had to be in the bath for someone to wash my hair ( the height of humiliation... ) would have been hard for someone to get in the shower with me.
Sometimes there is an actual need for bath.
