For timber frame constructions and the bathroom on the 1st floor, an important tip: Try to incorporate a waterproof "black tub" (made of bitumen) during the renovation. It can be done well as a DIY project and protects the rest of the house below against possible moisture escaping, such as unplanned flooding, etc. (which of course should never occur).
