This extension kit is built to work with the GROHE 35 026 000 GrohFlex universal rough-in box, giving plumbers and remodeling professionals a reliable solution when wall depth adjustments are needed during installation or renovation. The kit integrates seamlessly with all GrohFlex thermostatic trim designs, making it a versatile component for both new construction and retrofit projects. Plumbing contractors and bath remodelers frequently need extension kits when tile surrounds, wall assemblies, or structural elements push the valve position deeper than standard trim will reach. This GROHE extension kit solves that problem cleanly and without the need for custom fabrication or adapters. The StarLight chrome finish is a hallmark of GROHE quality. It uses a multi-layer coating process that produces a smooth, mirror-like surface built to resist tarnishing, corrosion, and everyday cleaning wear. The finish holds its appearance over years of regular use, making it a practical choice in high-humidity bathroom environments. Volume control is a critical function in any shower system. This extension kit supports smooth, consistent volume adjustment by maintaining proper valve alignment and seating when the rough-in box sits deeper in the wall. Installers get a clean, professional result without trimming out-of-spec or forcing hardware to fit. The GROHE 47889000 is part of the GrohFlex product collection, which is known for its modular, flexible design philosophy. Components within the GrohFlex system are engineered to work together, reducing compatibility guesswork on the job site. GROHE is a German plumbing brand with a long track record in water technology, precision engineering, and premium fixture manufacturing. This extension kit reflects that standard, offering a straightforward, durable solution for professional plumbing installations where wall depth accommodation is required.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCompatible with the GROHE 35 026 000 GrohFlex universal rough-in box for volume control applications\u003c\/li\u003e\n\u003cli\u003eIntegrates with all GrohFlex thermostatic trim designs, supporting modular system flexibility\u003c\/li\u003e\n\u003cli\u003eGROHE StarLight chrome finish resists tarnishing, corrosion, and wear in high-humidity environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe GROHE 47889000 GrohFlex Extension Kit provides plumbing professionals with a dependable, finish-matched solution for volume control trim installations where additional wall depth clearance is required.
