Hello,
I have a house from 1964 with 15cm Siporex (60cm wide) in the flooring. I recently renovated the bathroom and changed the bathtub's position from along the exterior wall to perpendicular to it. The span between the load-bearing walls on the floor below is 319cm.
In the Top View of the bathroom, you can see the previous bathtub placement and the new placement (in a nice red color). In the Cross-section of the bathroom, you can see the flooring and load-bearing walls in the basement.
Since the bathtub will be shorter, it will need to be slightly deeper, and therefore most likely a bit heavier when full, but certainly a higher load per area.
The question is simply,
should I stop worrying and fill up a bath, or should I reinforce in some way first?
Grateful for any input!

I think you should stop worrying! If you are going to calculate on older lightweight concrete structures, you need access to the lightweight concrete handbook, which nowadays you have to hunt for at second-hand bookstores. However, a water-filled bathtub must be considered a short-term load, and the center of gravity hasn't shifted outwards that much.
