Designing Kitchens and Bathrooms - Redo shower walls & floor

33 years ago when I built my home I had my bathroom and shower floors done with Torginol ( think thats how it is spelled). To make a long story short, they are starting to look pretty bad. Problem is no one does Torginol anymore. Basically what Torginol is is epoxy put on the wooden walls and cement floor, sprayed with different color fragments and overlaid with several coats of Polyurathane. What I have in mind to do is sand off the old Polyurathane apply new epoxy, fragments and New Polyurathane. Do you think that a good idea? My 2nd plan is to just install those plastic wall and floor coverings over the old Torginol and let it go at that. What do you think?? Good idea or can you suggest something better and faster? The wife is on my case to get this job done.
Thanks, Ron

I don't know about repairing what you have. Here is what appears to be a start on a current source of that sort of wall and floor treatment.
