We recommend the following 8.5 kW showers as the most suitable retro-fit replacement models:
Stanza 8.5 white
Stanza 8.5 black
These showers can also be fitted as replacements for the ES550 although some alterations to the pipework and wiring may be required:
8.5 se - with a gloss white finish
8.5 cse - with a satin chrome finish
