RM1500 for how many square feet? mine is less than 500 feet?
and where to get this product?
i did ask whether need some sort of sealant or not and both installer and "polisher" said no.

try to compare at least 2 quotation. all the experience tilers were working with marble last time. just that they prefer easier job, that is to lay tiles.

i think 100 to 120 square feet is too small a job, tiler will certainly charge you higher.

already PM you.
