Aqualisa was the brainchild of founder Derek Goldsmith, an engineer who bound together two dissimilar metals to create the Bi-Metallic Coil in 1976, making cold showers a thing of the past. In the 00s, Aqualisa introduced the digital shower, which provides consistent, no-fluctuation water temperature at the touch of a button. Over the years, Aqualisa’s smart showers have become ever more sophisticated, particularly with the recent introduction of the QTM, which has personalised functions promising the perfect shower.
