Selecting the appropriate material is critical for durability and maintenance. For bathtubs, Acrylic is the most popular choice due to its excellent heat retention, lightweight nature, and ease of repair. For a premium feel, Cast Iron offers unmatched longevity and a high-end finish but requires reinforced flooring due to its weight. For faucets and showerheads, prioritize Solid Brass construction with a PVD (Physical Vapor Deposition) coating to ensure resistance to corrosion and tarnishing in high-humidity environments.
