I've tiled the floor of my new en-suite. I've bought a plastic shower tray, which says that it should be stuck down with adhesive.
Do I use normal grab adhesive? Or do I use tile adhesive?
I want to make sure the tray is well stuck down: it doesn't sit quite flat on the tiles so I plan on weighing it down at the ends while the adhesive cures, with the hope that when I take the weights off later it doesn't bend back up.
