Contractor changed grout; should I be miffed?
I specified Laticrete epoxy grout for my shower walls and floor - basically white with silver shadow grout. There's accent tile that's handmade, and required sanded grout, so my contractor and I discussed how he would need to use 2 different kinds of grout. Soooo, the woman at the tile store talks him into what she called an upgrade, which would work for the grout lines on both the subways and the handmade tiles. Having just insisted he move the drain for the bathroom sink, I let this go, rather than quiz him about what this meant. I got home today, and he has grouted the shower with Laticrete Permacolor, which is a cement grout.
So I have 2 questions: do I pitch a fit about this, and do I insist that he change to epoxy on the floor, which he has not done yet (12x12 tiles with moderate grout lines)? I have seen BillV say that epoxy is usually overkill (we have no hard water problem, and there's no countertop involved), but I was looking forward to a lower maintenance grout. Is there really a big difference? Should I go ahead and have him seal the Permacolor?
Thanks in advance for your advice!
