My order of preference is: 1.bath, 2.wash, 3.shower. I don't agree that a bath takes longer, particularly if washing my hair. It's thick and shoulder length, so it's quicker for me to put my head under in the bath when washing it, then just use the shower head for a final rinse off. Washing shampoo, then conditioner off in the shower takes me ages. Also, I can get things done while the bath is filling up, so I don't consider that time wasted.
Reading this thread, I do feel blessed that I am still able to get into and out of the bath - long may it continue!
