Thanks, Frank, good advice on checking the calibres, I'll make sure I do that.
I'd agree that cheap and quality don't often go hand in hand (hence my seeking advice), but sometimes expensive means profit and not necessarily quality.
And, every once in a while you happen upon a true good deal, like this forum, I'm astounded at the quality of info I've gotten for free! By the way the tiles are 2.50/ sf 13x13.
Anyway, this porcelain looks a lot like travertine- something I'm not finding much of, they tend to all look like wanna be's to me. BUT, if it's going to be a nightmare to work with or not hold up then I certainly don't want it!
I've found a fair amount of info on this site about how to tell if a stone is good quality, but not porcelain. Maybe that's because porcelain doesn't have the same inherent problems?
Unfortunately the box, which identifies the tile as Mediterranea brand, doesn't list the PEI rating. How bad of an indication is this? I looked at the website for Mediterranea, but no specs. They claim to have a 20 yr track record in the US, but well, I was hoping for some unbiased, experience driven feedback.
