I have a molded acrylic shower surround that has a molded in soap dish. Above the soap dish is a grab bar/washcloth hanger that is captured between two raised portions of the surround. There was a grommet on each end that seals out water from leaking past the bar. These grommets have failed and fallen out. I would like to replace these grommets but I have two problems. One, I can't seem to find any gromments that match the old ones. They are a stiff white/ivory plastic (not rubber). The second problem is, of course, that I cannot remove the bar since it is captured inbetween the molded acrylic. I think I can repair this if I can find the grommets and if they have a split in them (or I can split them) so I can get them around the bar before sliding them into the hole. I do not see any markings that identify the maker. Anybody know where I can get grommets like this?
