I did my tiling last year. The labour cost was by size. 60cm x 60cm is RM13.50 psf with sand screeding for floor, RM8.50psf without plastering for wall. For cutting 45 degree for the edge, it was RM8 per foot run. Remember to ask what brand and type of cement gum and grout lines for tiling. Weber? Sika? MAPEI?  Even for the same brand, there are different grades.
