Hi all, I am looking to fit a Mira Flight Low Profile 900 x 900mm Stone Resin Quadrant Shower Tray which has reinforcement underneath, please see attached picture.
I was hoping to fit with CT1 silicone but where the radius edge of the tray is (red section) it needs raising up about 3mm to be perfectly level. What are my options.
Could I put more silicone around the radius part and then put some plastic packers around the edge to raise the tray up or have I got to do a cement and mortar bed?
