Update, apparently I do know what I'm doing.
So after meeting the tile shop manager, who would argue black white, I was told that I had not started against the wall with a full tile, and that the rectangle tiles should go across the floor,and not up along the floor, along with other such BS, :incazzato::incazzato:
Also the client would have to buy another 10 or 11 boxes to get enough of the large tiles to finish his floor!
More investigation got a number for Carmen Ceramicart in Spain, who initially denied any probs, Eventually I was able to get a number for the guy who deals with Eire, and who happened to be in Ireland at the time
He eventually admitted that yes, On larger floors, they have had this problem, and he is now trying to source more 45x45 tiles of the same shade for the client, take about a week.
That won't help me much today, sat on my A**e, but I am glad that after 20years, I actually do know what I'm talking about. And hopefuly if you ever come across these tiles, You will be better armed before you begin.
It does seem like a fairly basic error on the manufacturers part, I mean how hard would it be to add an extra 45x45 tile to the pack, they would still be £xx per sq mtr
I read through this thread again, and thought I should say that the tile sizes I posted where approximate, and they do allow for grout etc
