Cheers lads, I can't actually remember what they were called, 60 x 30 porcelain, they were from a tile shop in Dumfries, will see if I can find out for you, job took seven days to complete, most of which was prep work.
if I understand it rite you've put cement all around that open box in pic 2? was it ground level or if not wouldn't that be too much weight for the ceiling below?
