I’d like to tile my bathroom, including shower area, and my kitchen, including splash back area, with white metro tiles. My wife wants white grouting. I’ve been recommended Bal Micromax 2 grout but I’m not sure cement based grout is a) right for the bathroom walls (and floor) or for the spashback cooker/sink area and b) will stay white? I’ve also read I should be using epoxy - or more likely getting someone more experienced to use it! I’d be grateful for any advice. Cheers
