spare the headache,  get a contractor to quote the workmanship, for my case  usually rm2-3/sq foot.

measure the kitchen area, buy the tiles yourself  seller might ask if u need skirting, etc, they will add further.
(i bought at jln ipoh, much cheaper from the selayang white horse factory. U can go to selayang factory to get some ideas/design from the display, but take down the tile codes that u r interested, and buy elsewhere cheaper)

u also need to buy the "susu"  to soak the tiles first, apart from tiles cement.

for kitchen area choose the less shiny to prevent slippage, shud water/liquid  splashes onto tiles.
