You will find even more possibilities.
Since our bathroom is not going to be huge, we thought there wouldn’t be many options. I moved the sanitary fixtures back and forth on the computer like you did, inserted partition walls, etc. In the end, it stayed with the version that was already drawn in the draft. Everything nicely pressed against the walls all around. To at least loosen up the bathroom a bit, as an alternative a hexagonal tub was possible. In the end, the floor plan remained practical, but nothing special.
On Saturday we went to the consultation at the sanitary wholesaler. In the end, a bathroom design came out that will probably be cheaper and still nicer than the version we had planned before. Instead of the hexagonal tub, we can take the much cheaper normal tub, and the shower, which is more important for us, will even be bigger, but without expensive glass doors. This all resulted from inserting a partition wall (tiled at the bottom, fixed glass pane at the top), with a large shower to the left of it and the bathtub to the right. We hope our construction company will approve this as functional.
What shocked me a bit were the prices. We had planned a certain budget for it additionally, but with the stupid sanitary stuff, prices shoot up as soon as it deviates a bit from the 08/15 standard model. Unclear. I’m curious what will be at the bottom of the offer in the end.
