This Malva mono basin mixer is from Roca’s new generation of Cold Start brassware, the default start position is cold water. The handle needs to be turned to the left to gradually introduce the hot water – it’s only at this point that the boiler is engaged. This simple fact that the opening of a tap avoids the unnecessary operation of the boiler becomes a significant energy saver, reducing CO2 emissions into the atmosphere. Comes supplied with a pop-up waste.
