Installation products are used to perfectly seal shower trays once installed in an already tiled shower enclosure. We offer an assembly kit that contains RAVAK Professional sanitary silicone, self-adhesive tape and two covering strips. The assembly kit is used to flawlessly seal the shower tray once installed into a fully tiled shower area. The shower tray is thus perfectly and functionally connected to the bathroom wall without interfering with existing wall surfaces. The universal mounting kit is suitable for all shower trays designed for corner installation. For trays installed in a recess, you will need to purchase an additional cover strip.
