In the 90s - early 2000s, several of my friends lived in such houses. First, we went to the public bath twice a week. One of her friends had her own bathhouse, and for her it was even a sign of a certain superiority over us, mortals, who are forced to dash in small bathtubs, and in September-October, when they could turn off the hot water for several weeks, in basins, shivering from the cold ... Secondly, there were usually columns or wells next to such houses, so there was water for washing.
well, och help wipes - and there are hands, and make-up from the face and a lot of stuff like "wipe your shoes a second before going out". in conditions of an irregular water supply, och an acute issue arises with the hair - the fact that on the head, dry shampoo helps (you can live for about a week), and for those who, I apologize, shave off - good foams that allow you to do well, almost without water at all. you can't go about washing on a crooked mare - but all kinds of antistatic sprays calm down a bit - and any animal hair will not stick once again, for example, and they don't smell disgusting * laugh *
I didn't remember anything useful ) (
As a child, I lived in such a house in the village. On weekends or more often there was a bath. Fortunately, then I was still little and I was not worried about the lack of a bathroom.
I think you can adjust to the situation. For example, to carry out washing procedures in the kitchen sink, and keep cosmetics in a convenient cosmetic bag and carry them with you. And other little things.
