ᐅ Bathtub on a screed floor? Should underfloor heating be omitted?

Hello,

I am wondering which solution is technically the best:

Should the bathtub be installed on the screed or directly on the concrete slab?
Should the underfloor heating continue beneath the bathtub or be omitted there?

There are so many pictures, opinions, ... it is clear that the entry height is lower if the bathtub is placed on the concrete slab ... and the sound insulation is better with screed.
But which option is technically "better" or "correct"?

Regards

There is no single correct answer. Both options are basically possible, and you have already recognized the advantages and disadvantages.

We reduced the step-in height in our old house by adding a tiled step in front of the bathtub and placed the bathtub directly on the screed. This worked quite well.
