Increase quality reflection

Hi all

I m doing an architecture visualisation scene.
But I ve an issue withthe reflection, you can see it in attached files ( screenshot )

The storage box reflect right, but the bath are very aliased.

I tried to increase all quality setting at max values, but I’ve still the problem. ( sphere capture quality, screen percentage, Temporal AA, etcc…)

How to fix the issue ?

I ve another problem : the reflection without roughness map are very grainy, I don’t know how to improve that.

Thanks,
