We almost completely took the standard equipment from the construction company, as it is already in the mid-range segment and appeals to us. The additional payment will probably be around €1,000 - €1,500. Bathroom furniture was expensive during the sampling (not included in the standard). 1.80m wide washbasin cabinet for over €3,000. Now we are having everything made by a furniture maker from Poland, only the washbasin top comes from a regional stonemason (natural stone). With high-quality materials, we come to a much cheaper price.
I think we will do something similar now. We let the sanitary trade install the connections and piping, and from the tile edge, we will do it ourselves. For example, we also will not spend €600 on a simple toilet bowl. I just don’t see the point. Regardless of whether it has a "the-wurst-slips-up-to-orbit coating" or not. Since we are only dealing with the trade in summer 2023, I assume there will be craftsmen available for it, but aside from that, you can really install a toilet bowl, faucet, and wall cabinet yourself without having completed 3 years of training and 5 courses.
