Grohe Brushed Nickel Square Shower Arm 15 Inch Rainshower Extension

GROHE 15” Rainshower Shower Arm – Durable Design for a Fresh, Functional Bathroom

Elevate your shower experience with the GROHE 15” Rainshower Shower Arm—a robust solution that combines long-lasting performance with effortless style. Designed for modern bathrooms, this arm features GROHE’s StarLight finish, engineered to resist water spots, stains, and wear over time. Unlike traditional finishes that fade or dull with use, StarLight wipes clean with a simple cloth or sponge, keeping your shower arm looking vibrant and new for years to come.

Measuring 15 inches in length, this shower arm includes a square flange for secure mounting to your wall or plumbing. Its ½” NPT male threads ensure a tight, leak-proof connection to most standard shower heads—compatible with nearly all models except the Rainshower Jumbo 28 783 (always double-check compatibility before purchase). The durable metal construction means it withstands daily use without sagging or warping, making it a reliable choice for high-traffic bathrooms.

Installation is straightforward thanks to GROHE’s included resources: a detailed specification sheet and step-by-step installation manual (both available on the manufacturer’s website). Whether you’re tackling the project yourself or hiring a professional, these guides simplify setup so you can focus on enjoying your refreshed bathroom space sooner.

For those seeking a shower arm that blends durability with low maintenance and versatile compatibility, the GROHE 15” Rainshower Shower Arm is the smart choice. It’s not just an accessory—it’s an investment in your bathroom’s longevity and beauty.
