Grohe Rainshower 310 Mono Head Shower Set – 422mm Wall Arm (26557 / 26558)
The Rainshower 310 Mono is a single-spray head shower — one 310mm face delivering one generous rain pattern, with none of the mode buttons or dials that clutter a multi-function head. At 310mm it covers the shoulders properly, which is the whole argument for a head shower over a hand shower on a riser.
This set is supplied with the 422mm wall arm, so it fits a standard through-the-wall installation and does not need a ceiling void.
- 310mm single-spray head shower with 422mm wall arm
- GROHE DreamSpray for even water distribution across the face
- GROHE SpeedClean anti-limescale nozzles — wipe the silicone nubs clean
- GROHE StarLight finish — scratch and dirt resistant
- Choose standard flow or the 9.5 l/min water-saving version
