Hi tiler seng, My living room size is 3.6 x 6.6 meter. Currently it is installed with ceramic tiles 45 x 45 cm. May I ask, is it possible to overlay with homogenous tiles 60 x 60 cm without hacking? if can, How much will you charge? If not possible, how much do you charge to hack and lay homogenous tiles for my living room? I will just use a standard tiles ($2.4/psf or cheaper) This e-mail is confidential and may also be privileged. If you are not the intended recipient, please delete it and notify us immediately.
