Proper Job

porcelain is about the best mate but i would not go for a glazed version its not has hard wearing. You really need to be looking at a grade 5 porcelain. You could also go for a natural stone product like granite. If you go for a natural product at least you could sand out any scatches and fill chips in. For cracking thats when there not fixed correctly. Other option would be quarry tiles mate very hard wearing and get better with age.
