Make of Bath suggestions

[Yanni]

I am looking for the most steady bath for up to max £400.
I do not want a steel bath as it is for a rental but looking for something steady.
Tried various make before like Ideal Standard, Carron and when you walk in the bath you can feel the floor moving slightly despite all the brackets and screwed on the floor.

Any suggestions?

I would suggest the issue is not the bath, but the installation. Have you thought of reinforcing the floor and framing the bath internally with timber? You could also strengthen the floor with ply or noggins.

The floors, we generally remove the floorboards and ply with an 18mm ply first.
The bath is screwed down well, there is always a week area a bit behind the drain hole which is usually where you are standing to have a shower, plus I'm not impressed with overall rigidity despite all the prep. My mum in Greece has a steel bath that is build like a tank. I am looking for something strong but not steel as if it chips then you need to re-enamel it.

Has anyone tried Abacus baths?
