Is there a way to remove a bathroom basin that is supported by a pedestal and attached to the wall with sealant without damaging tiles?
12" hacksaw blade in paw pushed against tiling, carefully?, depends on the gunk that the installer used.
Only thing I can suggest is disconnect trap,& connections to taps, remove fixing screws, & applied light pressure to front of basin, & try working a scraper down between the back of basin & tiles. Just hope it hasn't been gripfill to the wall like the one was here, ended up having smash basin to remove it.
Yes, but I would carry on slicing across the top with the stanley(or a sharp chisel)on the tiles. Every cut should allow the basins weight to pull it a bit more away from the wall. Mr. HandyAndy - Really
