Cutey! The only way to bathe. No soap in the tub. Surprised it hasn't caught on in the west, I mean a separate wash area on the side and then the tub to soak in. They make whole units that just slip into the space during the construction of the house or apartment, or during reconstruction. From cheap to most elaborate available. Two people or more if children with an adult, can easily wash and bathe at once. Everyone be clean before getting in the tub, or at least rinsed off. Generally the nightly ritual when the kids are young. Get the kids to scrub the old man's back, and vice versa. The whole family uses one tub of water per day, and it stays pretty clean.
