Hi there, We just bought a resale 3 room hdb flat and it's under renovation right now, we engaged ID to do the works and was thinking to put a tempered glass as kitchen backsplash, i was quoted by the ID $900 for a 9ft length, i found it too expensive though so still undecided to go with it or not, kindly help us whether this price is reasonable? If not, where can i get it cheaper including installation? Please help..Thanks
