Depending on where you live your shower can take a lot of abuse from hard water. Hard water can clog up important accessories like shower handsets causing them to be less efficient than they once were. Now you could go the whole hog and buy a brand new shower but this isn’t the most cost effective way to go about things. We’d recommend replacing the parts you’re having issues with which is why we’re working closely with Aqualisa to ensure their spare shower parts are available. This Harmony handset features 4 fantastic spray modes and a huge 105mm diameter shower head. It’s designed for use with electric showers and comes finished in chrome.
