I ordered my wet room shower tray and it came the next day, I was pleased. There were no fitting instruction so I beded the tray down on 50 mm cement and sand. Three days later the tray had parted from the cement. I called the supplier Tile Fix and they gave me the manufacturers phone number. They said fitting instructions should have been included and also a tube of adhesive to glue the trap to the shower tray. The tray when fitted to a concrete floor needs to be fitted with tile adhesive. I am disappointed with my experience and feel the price I paid for this product is completely over the top. .
