Concrete usually depends on foot run, as other posters quoted.

For tiles pricing, it depends on your choice. If you use cheap porcelain tiles you can get it cheap but the aesthetic aspect won't be there. If you use quartz stone/ marbles you will likely pay much more. If average and acceptable usually people opt for porcelain tiles but make sure you choose full bodied tiles if can. In my case I oped for 2x2 full bodied porcelain tiles that costs RM24/piece.
