Grohe 26636en1 Tempesta Wall Union Round

Product Description

The GROHE 26636en1 Tempesta Wall Union is a shower wall connection fitting designed for use with handheld shower systems and slide bar setups. It serves as the fixed mounting point where the shower hose connects to the wall water supply. HVAC and plumbing professionals, remodelers, and plumbing contractors rely on wall unions like this one to provide a secure, leak-free transition between the in-wall supply and the flexible shower hose. The 26636en1 is part of the GROHE Tempesta collection, which is known for its clean, round profile and modern aesthetic that fits well in both residential and light commercial bathroom applications. The fitting features GROHE StarLight coating, which is a highly polished surface treatment applied to brass or metal components to resist tarnishing, corrosion, and everyday wear. This coating maintains a bright, consistent finish over years of use without requiring special cleaning products. A built-in check valve is included with this wall union. The check valve prevents backflow, meaning water cannot travel back from the hose into the wall supply line. This is an important feature for code compliance in many jurisdictions and adds a layer of protection to the potable water system. The universal design of the 26636en1 means it is compatible with all standard shower hoses and handheld shower heads, making it a versatile choice for replacement or new installation projects. The round shape integrates cleanly into tile walls and works alongside other Tempesta collection components. This is a direct replacement for Grohe 26636001 and Grohe 26636EN1 variants.

• GROHE StarLight coating resists tarnishing, corrosion, and daily wear for a long-lasting polished finish
