Hi, it is possible to repair/patch fibreglass with fibreglass matting/cloth/tape and resin but most plumbers will not feel confident working with fibreglass (its a skill in itself). Your best bet for a fibreglass patch repair would probably be a car body/boat repair technician. It may well be more cost effective to replace the tray section with a new tray section, associated waste fitting and re-do the tanking partially up the walls as most wetroom specialists would be willing to do this work. Hope this helps
