Struggling with fussy shower valve installs in tight spaces? The GROHE GrohSafe 3.0 Shower Rough-in Valve is here to simplify your project—from start to finish. Built for quick setup in even the most cramped environments, its compact design fits snugly where others might not, thanks to a flat back that mounts securely to standard cross braces. Perfect for thin walls or steel structures, it installs smoothly without extra hassle.
Crafted from durable DZR cast brass (engineered to resist corrosion and long-term water exposure), this valve combines strength with reliability you can trust. But its clever engineering shines during maintenance: the flush plug lets you test or clear your plumbing lines without removing the cartridge (sold separately), saving time and mess. Secure it all with a stainless steel retaining ring that holds the plug and cartridge in place—no screws needed, just a leak-proof fit that keeps things steady.
Installation gets an extra boost with the included plaster guard—it shields the valve during setup and doubles as a mounting support for thin walls. Plus, its back-to-back design lets you quickly reverse hot and cold water lines if needed. Whether you’re working in a compact bathroom or multi-unit space, the GrohSafe 3.0 delivers a seamless experience that stands up to tough conditions. Trim included—cartridge sold separately.
