Install one in the bathroom of Handyman Towers - never installed a shower tray before.
Stone type tray with 5 adjustable feet, but no method of attaching feet to floor - like on a bath, and no method of attaching tray to walls, so it doesn't walk about.
I seems pretty stable, but I'm going to make up some brackets to fix it in place anyway - but is it normal for them not to be fixed?
