Product Description

The GROHE GrohSafe 3.0 Shower Rough-in Valve is engineered for quick, easy installations no matter the situation. Compact body allows for a hassle-free fit even in tight spaces. Flat back ensures solid mounting on a standard cross brace, and installation on thin walls or steel is sturdy and secure. The PEX elbow connections allow you to connect PEX piping directly to the valve, from floor or ceiling supply lines, without additional elbows. Made of DZR brass to resist corrosion, the GrohSafe 3.0 is equipped with a flush plug, allowing you to quickly test or flush lines with ease. Stainless steel fixation ring keeps flush plug and cartridge in place without screws. Cartridge sold separately.
