I used Fusion Pro grout in one bathroom and epoxy grout in the other. After four months the epoxy grout looks perfect, LATICRETE SpectraLOCK I bought from a local big box store. The Fusion Pro was from a local tile supply shop that recommended the product. Fusion is easier to work with and cost less than epoxy but I am worried its not holding up in the shower pan. The grout was allowed to set for two weeks before water was introduced, more than the min 3 days.
