Aqualisa is one of the UK's most successful shower manufacturers. They have a reputation for innovative design, high quality manufacture, and excellent customer service. From the introduction of their revolutionary bi-metallic thermostatic shower valve in 1977 to the launch of the first Digital Shower in 2001, they have always been at the forefront of shower design. In 2006 they also launched the very first, entirely wireless and batteryless remote control. The bi-metallic valve that was launched in 1977 is still at the heart of Aqualisa's phenomenal success. This patented and unique technology means that an Aqualisa Shower can deliver more water to the shower head, resists limescale build up, and can control the temperature more accurately than conventional mixer showers. Aqualisa is considered as the market leader in design and quality, and offer a 5 year guarantee across most of the range.
