because the water could seep through the joints between the new tiles and sit between the two layers and affect the seal and also raise the height of the floor and affect the slope to the waste outlets..but, why do you want to retile if you're not using the bathroom??...for immediate resale consider bathroom wall to wall bathroom carpet, new wall paint, new vanity, taps and light fittings which should also be cheaper than tiling over the top and, if it's not allowed by the body corporate, it will be a risk to future sales as it should not satisfy a proper building inspection

Sorry about what happened to you Niamh. Those tiles look lovely when done right. I hope you can get it resolved somehow. "Whatever you do don't get the same person back to do it again, (even if you hadn't paid them) Biggest tip I can give to renovators is if the trade hasn't cut it on the first run then you're pushing it uphill to try and get it over the satisfactory line. Better to cut your losses and pay to get it done by more experienced tradesperson, more often at a higher cost." Paul Di Stefano Design, I wish the internet had been around to give me that valuable bit of advice many years ago.

You may be lucky & the tiles may come off easily if just laid (we just did this in our shower). Worst case when they pull them off they may damage the membrane, in which case they will need to repair it, so it is just the time of the repair & drying, before they can relay the tile. If it's important to you, get them to fix it, as long as you can accept the worst case scenario of the extra time (that is what we did, and then the membrane was fine anyway). Good luck.
