edit the current tub render and change only the exterior surface texture to match the attached stone sink reference make the outside of the tub more like the sink rougher more carved more irregular and more natural looking with a hand chiseled limestone finish and stronger variation in the stone face the exterior should feel more rugged and sculpted not softly textured or uniform keep everything else the same same tub proportions same circular shape same beige limestone color same smooth honed interior same rounded softened rim same center drain the goal is for the outer wall texture to closely resemble the reference sink image while preserving the overall tub design
