Hi calaislily, Thanks for the advice. I don't think I have the option of overlaying the tiles since I am pushed into the renovation because the wall tiles are coming off. As in the tiles are holding together but peeling of the wall. Because it is my parents' place, I don't need it to be aesthetically nice, just good and functional. Does your 3k-5k includes all the rewiring and wash basin and toilet bowl and piping? If so, I think it is a reasonable price to pay. Just find it hard to swallow paying 3k-5k if only for hacking and retiling work. Haha. Also, if you would be so kind as give an example of your cost for re-doing your bathroom, I would be very grateful.
