Strictly not a d-i-y question I guess, but I figure you guys may have some useful advice.
We're in the middle of a bathroom re-fit. The walls are tiled except for the bottom row and the ceramic floor tiling has just been 'completed' We're now waiting for our contractor to return to finish the tiling and fit the sanitary ware. The problem is the floor does not appear to be level by spirit-level or by eye. The contractor has already replaced and over-boarded the existing flooring (which he claimed was 'goosed') so I can't really see any reason why he couldn't get the ceramic floor tiles perfectly level.
So my question is; how much fall across a 4' stretch of tiles is acceptable? Also, how much difficulty would there be in lifting and refitting the tiles? My guess is that it would be almost impossible to remove the tiles intact, but that just getting them off and going back to the board shouldn't be an enormous problem. I'm guessing that removing adhesive from plywood is at least as easy as getting it off masonary.
Many thanks for any advice.
