I have an old Frost light niche that I need to replace or rebuild. My local supplier says that there are no current niches as big as the old Frost niche. My problem is that this is for a fiberglass walled pool and I think I would need a niche at least as big as the current niche so that it fits the hole in the wall. My goal is to avoid any type of fiberglass work. I could use a gasket kit, but I have had no luck finding replacement parts/kits for this niche. Anybody out there know where I can find either a gasket kit or a niche?
