  Product Fiche


The GSX Deluxe 8.5 is our top-of-the-range electric shower and one of the newest electric showers to be added to our range. Ideal for use by all members of the family, this stylish white and chrome electric shower has an adjustable height shower rail system to allow comfortable showering for the whole household. The shower head has 3 different spray patterns, and a clickable setting change between each pattern allows each spray pattern to be easily selected.

Easy To Use Gainsborough Electric Showers

As with all Gainsborough electric showers, the new GSX Deluxe 8.5 is easy to operate, with a start/stop button control and push button heat setting controls. In addition, an illuminated multi-function LCD screen provides a unique feature not seen on any of our electric showers before and provides comprehensive visual information for the user including:

  • Shower temperature*
  • Shower duration – to encourage speedier and more economical showering
  • Heat setting selected
  • Power on standby feedback – providing easy to identify electric power feedback
  • Low pressure warning indicator – in the event of water supply issues
  • Multi error message feedback – allowing the user to easily identify faults and find remedial action

Electric Shower Safety Features

Safety features are plentiful with our new electric GSX Deluxe shower. As well as the low pressure warning indicator on the LCD display, the shower features an intelligent heat setting switch down which automatically selects a lower heat setting if an excessively high water temperature is identified. The new GSX Deluxe 8.5 also has a Phased Shutdown feature which flushes hot water from the shower once it is turned off. This safeguards the next user against scalding by ensuring all hot water is removed from the system whilst also helping to reduce limescale build-up.

Electric Shower Guarantee

Our new electric showers come with a 2 year parts and labour guarantee providing you with complete peace of mind.
