edit the current tub render and change the rim profile to match the attached reference image make the top rim slightly rounded and softened with a smoother more eased edge rather than a flatter or sharper profile the rim should feel subtle natural and comfortable like the reference sink image rounded but not overly thick or bulbous keep everything else the same same tub proportions same circular shape same rough exterior stone texture same beige limestone color same smooth honed interior same center drain the goal is to make the rim edge softer and more rounded closer to the reference image
