Bathtub - GU does not want to set it lower

And by the way, a nice side effect: The entry height is more comfortable.

That is the only nice side effect. Otherwise, there are disadvantages such as missing heating surface in the bathroom.

That the fittings don't fit is simply a planning error.

However, there is nothing per se against placing the tub on the bare floor; it's a matter of taste.

The general contractor's argument is nonsense. If the tub leaks, the water flows into the building anyway.

Not nonsense at all. Because of the walk-in shower, there is an obligation to seal the entire floor in the room. This takes place above the screed. If you exclude the tub from this, you initially waive the sealing unless you agree to extend the sealing (in whatever way) also to the bare floor or tub.

Just keep at it and seek the conversation again. In the end, it’s all about the money.

The topic of sealing is nonsense, but compared to the GU variant it involves extra effort.

Bathtub on screed: seal the entire bathroom once before the bathtub support is installed and done.

Bathtub on raw subfloor: leave out the screed, then if necessary level the height for pipes under the bathtub. After that, create the first sealing layer under the bathtub including connections to the wall and sealing on the screed. Then install the bathtub support. Then create the screed sealing and integrate it with the bathtub support.

As far as I know, the bathtub support is made of Styrofoam or similar material.

The topic of sealing is nonsense, but it involves additional effort compared to the GU variant.

Bathtub on screed: seal the entire bathroom once before installing the bathtub support, and done.

Bathtub on raw subfloor: leave out the screed, then possibly height adjustment for pipes under the bathtub. Then create the first sealing layer under the bathtub including connections to the wall and sealing on the screed. Then install the bathtub support. Then create the screed sealing and integrate it with the bathtub support.

Which variant do you suggest?
The floor structure is 17 cm.

Well, you are the builder. And I am not your site manager. For the higher effort, your general contractor will surely file a change order.

Aside from the fact that the tub stands there no matter what, it is not a heating surface anyway. The problem to be solved is, however, what will happen with the faucet. The builder ordered a functioning solution that is technically flawless. If the general contractor can only implement this with other (more expensive) faucets, that is not the builder's concern, especially since he is not a planner. It is certainly the general contractor's responsibility to choose the route he takes (he is also installing the heat pump), but the costs cannot, of course, be borne by the builder. He wants a tub with water in it. And that properly done and without additional costs.

You tend to generalize. How do you know that the builder did not require the parapet height? Or that the planning documents were created by an architect and the general contractor is only implementing them?

Every bit of heating power helps in the bathroom. I would not forego it either under the bathtub or in the shower, or see it as a disadvantage if the bathtub stands on the raw floor.
