The revamp, which will see the introduction of a revised brand logo, aims to capitalise on the burgeoning home improvement market.
The logo, created by design agency Carter Wong Tomlin, will appear on all its showers, and uses the 'q' in Aqualisa to represent a shower dial.
The agency has devised a set of straplines which will be used across all advertising and promotional materials, including 'Indulge with ...' and 'Relax with ... Aqualisa'. They are intended to reinforce the emotional pull of the brand.
The rebranding activity coincides with Aqualisa's launch of Axis, a range of high-tech showers.
Aqualisa showers are sold in bathroom showrooms and DIY stores across the UK.
