Grohe Rainshower Smartactive 310 Headshower Set Brushed Cool Sunrise - 26479GN0

Brushed cool sunrise is GROHE's own finish name for colour code GN0 - a brushed, non-reflective warm gold tone. It is not chrome, not brushed nickel and not matt black. GROHE catalogue the same 26479 head shower set in a range of other finishes, including chrome (26479000), so if you need to match existing fittings, check the colour code on those first. Because it's a brushed surface, follow GROHE's care instructions (linked above) and avoid abrasive cleaners.

No. The box contains the Rainshower SmartActive 310 Cube head shower and the horizontal 430mm shower arm. There is no hose, no handset, no wall bracket and no valve. GROHE also state that this product requires a Rainshower Universal rough-in box - 26483000, or 26484000 with the water-saving EcoJoy limiter - to be ordered separately, and you'll need a shower valve to feed and switch the two sprays. Have a look at our Shower Valves collection, or the full Showering range.

GROHE do not publish a minimum flow pressure for 26479GN0 - what they do publish is the flow rate measured at 3 bar: 25 l/min on one spray and 19 l/min on the other with the 26483000 rough-in, or a capped 9.5 l/min per water way with the EcoJoy 26484000. An unpumped gravity-fed system (loft cold tank plus hot cylinder) delivers a small fraction of 3 bar, so a 310mm head will feel soft rather than powerful. A twin shower pump like the Salamander Ora 2.0 is the usual answer: it boosts both the hot and cold feed and is rated at 1.2 bar at 15 l/min, 1.8 bar at 8 l/min and 2.0 bar at closed head. Two honest caveats. First, that's still below the 3 bar the flow figures are quoted at, so treat a pump as a big improvement rather than a guarantee of the headline flow rate - the EcoJoy 26484000 rough-in, which caps flow at 9.5 l/min per way, is the easier target. Second, the Ora 2.0 is designed to boost a single thermostatic shower on a positive-head gravity system - it isn't intended to run several outlets at once, and it won't work with a combi boiler. Message us with your system type before ordering either item and we'll sanity-check it.

Both are GROHE Rainshower Universal rough-in boxes with two 1/2" inlets, a DR brass connection unit and an installation depth of 75-105mm. The difference is flow. 26484000 adds GROHE's AquaCalibrator and EcoJoy limiter and caps the flow at 9.5 l/min per water way at 3 bar, which saves water and is far more realistic on a lower-pressure supply. 26483000 leaves the flow unrestricted, which is where GROHE's higher 25 l/min and 19 l/min figures come from. Neither box is included with this head shower set.

The nozzles are GROHE SpeedClean silicone jets - limescale on the face lifts off by simply rubbing over it with your fingers, and GROHE guarantee that function for five years, on the condition that you clean them regularly. That's the honest answer for the head itself: routine wiping, plus GROHE's care instructions rather than descaler on a brushed finish. If you'd rather treat the water going into the house, we stock Salamander's in-line catalytic water conditioners, which fit on the incoming supply to reduce limescale build-up across the whole property: the CWCOND02 (1/2" BSP-T, 3-25 l/min) and the CWCOND03 (3/4" BSP-T, 24-54 l/min). Note these are sized on your whole-house incoming flow rate, not on one shower's flow, and they're a water-treatment measure rather than a filter - they don't remove the need to wipe the nozzles.

Yes - 310 is the head size in millimetres, and Cube is GROHE's designation for the square-faced version of the Rainshower SmartActive 310 (the non-Cube 26475 is the round one). The set pairs that 310mm square head with a horizontal 430mm wall arm. Do check the dimensional drawing linked in Downloads before you set out the rough-in box, so the head lands where you want it in the enclosure.
