- INSTALLATION IN MINUTES: Very easy to install, usually under ten minutes. Unscrew the old shower arm from the wall, install the 15 inch shower arm with Teflon tape, and fix the 12 inch rain shower head. The thread is US standard size. The package includes a small wrench and Teflon tape. - EXTRA LARGE AND POWERFUL RAIN: The 12 inch shower head has over 140 nozzles for a high flow overhead spray. With the swivel ball connector, you can adjust to any angle. Enjoy a wide, gentle downpour that covers your body, with a massaging function similar to a spa. - STYLISH AND DURABLE: Made of premium stainless steel with a mirror-like chrome finish. Rust-resistant and durable, giving your bathroom a modern look. No plastic components—upgrade to a more comfortable shower experience. - SHOWER HEAD EXTENSION ARM: The 15 inch arm is thick stainless steel. The wall-mounted extender fixes the 12 inch head perpendicularly, preventing loosening and sagging and delivering steady rain coverage. Compared with adjustable arms, this fixed arm avoids issues of being too short, unstable, or leaking. - COMPATIBILITY AND PERFORMANCE: US standard thread ensures easy fit with most showers. The 15 inch arm and 12 inch head are designed to work together for luxurious overhead coverage. - PRACTICAL USE SCENARIOS: Master bathroom remodel for a premium rainfall experience; family showers with full-body coverage for kids and tall users; daily spa-like routine with consistent, soothing water flow.
