guys I am new here and need your opinion.
I want to change old tiles (1.5X1.5) to new ones (2x2) in my living room apartment (400sqft).

I have checked some shops in Jalan Ipoh but not sure how to differentiate grade 1, 2 etc and good brand. I think they have Citygres

can someone please advise where to get affordable and good quality tiles?

and please pass contact of cheap contractor...bangla also ok as long good workmanship. I have received ridiculous quotation like RM10K without tiles.

please help
