Black Slate Shower Tray HELP!?!

[k rogers]

Used a ceramic stool at the end of a new 1800mm black slate shower tray to hold soaps and shampoos. Two months later and the tray is now a warren of white scratches and an indelible 'ring' mark and other water marks. I used nothing to clean the surface harsher than dish washing liquid and a super gentle natural stone cleaner. These trays are not fit for purpose.

Just put a slate effect shower tray in, as wanted a non slip finish for safety. (over 75) Installer said it must be mopped after every use, as water can't drain due to surface not being flat, but happy to do that. Don't feel safe on shiny flat trays
