Does anyone know if there is a tried-and-true grout out there for tiling bathroom shower stalls that is mold and mildew resistant? I am considering using the Swanstone shower kit or tiling a new shower stall in my basement and am very concerned about mold and mildew. I hear that the Swanstone products are very good in regards to resistance to mold and mildew. However, I am also concerned that the Swanstone panels will start coming off the walls in about 10 years, whereas, tile is pretty much maintenance free (other than potential mold-mildew issues). Any and all comments are greatly appreciated.
