The shower head holder is made of solid brass, which is durable and reliable. Compared with aluminum and stainless steel, copper is strong, durable, and rust-resistant. Suitable for standard-sized shower heads: The top diameter is 2.2 cm, which is suitable for most standard-sized shower heads and hoses. 360° Adjustable Shower Head Holder: Designed for standard shower hoses, this adjustable wall-mounted shower head holder with 360° adjustable angle makes your bathing more free. Easy to install and use: Fix the base with the provided long screw to the chosen position on the wall, and screw the holder to the base, which is more stable than the suction cup and not easy to loosen. The chrome-plated surface makes our shower head holders bright and beautiful, and is a good choice for your bathroom.
