I need mosaic or 50mm sq max tiles for a 1200 x 900 wet area. A bathroom installation firm says porcelain is the only material hard-wearing enough for this, which I doubt, particularly as Topps sell a range of slip-resistant 50mm sq ceramic tiles. I also find unbevelled porcelain is very unforgiving ( and would also need sealing? which I want to avoid ). Would normal 50mm sq ceramic be ok for this purpose? Does anyone have views/suggestions on this?
