Use 24x48 or 30x60 tiles on floors and walls to stretch the room visually. Coordinate slab deck, curb, and niche pieces for uninterrupted lines. Choose epoxy grout in a matching tone for stain resistance, easier cleaning, and a seamless, gallery-like appearance.
Select living brass for organic patina or PVD-coated options for durability near salt air. Match drain trim, valve plates, and pulls for cohesion. Consider knurled details on handles to add tactile richness without overwhelming a compact, minimalist envelope or reflective palette.
