Quartz Touch is the name given to the lower spec Smart version of Aqualisa's old Q digital shower (aimed at trade buyers). It doesn't have the top-level fittings that consumers usually pick when selecting a product for themselves.
The Optic Q range is exactly the same technology as the Quartz Touch but is aimed directly at the more discerning consumer market, adding the following benefits:
1. A full-colour digital screen display
2. The top of the range 130mm Vita handset with 3 spray patterns (models with handsets)
3. A full size adjustable 250mm drench head (models with a drench head)
4. The easy to use one-handed pinch grip system for adjusting the handset on the riser rail (models with a drench head)
